3 AIR MOTOR FEATURES AND CHARACTERISTICS Air motors are compact and lightweight. An air motor weighs only a quarter as much and occupies only one sixth of the space of an electric motor of equivalent power. Air motors develop far more power relative to size and weight than most other motor types. Air motors can be stalled indefinitely without overheating or sustaining any other damage. They can be started and stopped repeatedly to an unlimited extent. Our air motors are explosion proof certified, in compliance with the European Union s ATEX directive 1//EU. For equipment used in potentially explosive environments., speed and direction of rotation can be changed easily using simple control methods. Output inherently adjusts to match the applied load. Controllable over a wide speed range. Virtually unaffected by hostile environment. Smooth start-up to minimize shock loading on transmission components.

6 INTRODUCING THE AIR MOTOR The air motor is one of the toughest and most versatile power units available to today s design engineer. It is easy to control over a wide speed range, and it produces maximum torque where it is often most needed at start up. The performance of an air motor is dependent on the inlet pressure. At a constant inlet pressure, ungoverned air motors exhibit the characteristic linear torque/speed relationship. Figure 1. The performance curves for an ungoverned air motor operating at a constant air pressure are illustrated in Figure. [] Stall torque Power Min starting torque Speed [] Figure 1 Figure However, by simply regulating the air supply, using the techniques of throttling or pressure regulation, the of an air motor can easily be modified. The free speed and torque can be regulated down to 0% for an LZB air motor. The free speed for an LZL can be regulated down to % and the torque can be regulated down to %. The shaded areas in Figure illustrate this. 0% 0 0% 0 The use of gear units Speed Air motors operate at high speed and, although they can be controlled over a wide speed range, the characteristics are not always suitable for the application. To achieve the required an appropriate gear unit can be selected. The ability to change the by use of a gear unit is illustrated in Figure. 0 0 Power :1 0 0 Speed 0% LZB 0 0 Speed 0% LZL Figure :1 1:1 It should be noted that all vane air motors produce a variable starting torque, due to the position of the vanes in the motor when it is started. The variation differs between motor types and must be checked on an individual basis. The power that an air motor produces is a function of torque and speed. All ungoverned air motors produce the same characteristic power curve, with maximum power occurring at around 0% of the free speed. The torque produced at this point is often referred to as torque imum. 1:1, :1, :1 = gear ratios Speed Figure The planetary and helical gear units used by Atlas Copco have a high level of efficiency that can be assumed to be 0%. The power remains virtually unchanged also when gears are used. ATLAS COPCO AIR MOTORS

7 METHODS OF MODIFYING MOTOR OUTPUT Throttling A throttle is usually fitted into the motor s inlet, although it can also be complemented with some throttling at the exhaust. You should never create a back pressure above 1 bar at the exhaust. Pressure regulation When using a pressure regulator it is mostly fitted into the motor s inlet hose. The use of pressure regulation is ideal when control of the stall torque is required and a high starting torque is not so important, Figure. % 0 Operating pressure 7 bar bar bar bar bar Speed Figure 0 Speed % Figure USING THE CATALOGUE Motor data, specification and performance curves For each Atlas Copco motor/gear unit combination the following information is presented in this catalogue. 1.

8 CHOOSING YOUR MOTOR The working point When selecting an air motor for a certain application, the first step is to establish what is called the working point. This is the point described by the desired operating speed for the motor and the torque required at that speed. The wide operating range of the air motor makes it probable that a number of motors could run with the same working point. However as it is most efficient to run an air motor at the speed imum, the motor that produces maximum power nearest to the working point should probably be selected. Other criteria that can influence the choice are minimum starting torque, stall torque and free speed. Power Air cons. The power required at the working point is calculated by: LZB-L-A Speed Figure Power = π x M x n [W] Where, M = at working point (in ) n = Speed at working point (in ) If necessary, one of the flow control methods can be used to modify the of a motor to meet the working point exactly (Figure 7). Example: A Non-reversible motor is required to run at 0 and produce a torque of. Selection of correct motor size is as follows: Power required (W) =.1 x x 0/ = 1 From Table the correct size of Non-reversible motor for this application is the LZB. Once the motor size has been identified, simply look at the performance curves for each motor variant and select the one with max. nearest to the working point. For the above example this would be the LZB-L-A Desired working point with standard motor at. bar (1 psi) with throttled motor with pressure regulator Speed Figure 7 ATLAS COPCO AIR MOTORS

9 Pressure regulation Sometimes the motor operates at other supply pressures than. bar. In these cases the performance of a motor must be re-calculated to ensure the working point can be achieved. To calculate performance at supply pressures other than. bar, multiply the data at. bar by the correction factors shown in table below. Correction factors Air pressure bar psi Output Speed Air consumption It is also easy to calculate the inlet pressure required to achieve a desired working point. Example: An LZB-L-A0-11 is required to run at 11 and produce 1. ; calculate the required inlet pressure to achieve this. For this motor imum the torque is 1. and the speed is 10. M 1 = desired torque n 1 = desired speed M = torque imum = speed imum n Calculate the ratios M 1 /M and n 1 /n Therefore M 1 /M = and n 1 /n = 0.7 Apply these values to the diagram in Figure and read off the pressure at the intersection point. The required inlet pressure is. bar (1 psi) Other applications require a certain stall torque. A motor s stall torque can be calculated by looking up the torque at maximum and multiplying this value by two. Where it is desirable to control the stall torque, the technique of pressure regulation should be used. Accelerating a load to speed Certain applications require the acceleration of a load up to a given speed. In these cases, the choice of motor involves complex calculations. It is therefore recommended that you seek guidance from your nearest Atlas Copco representative before proceeding. Shaft loading Always ensure shaft loadings are within the stated allowable limits. Silencing The noise generated by an air motor is mainly caused by the exhaust air of the motor. The noise level increases with speed and is greatest at the free speed. All Atlas Copco motors are supplied with a threaded exhaust port which, to reduce noise levels, can accept a screw in silencer. However, an exhaust hose can also be fitted, and when used with a silencer, it can reduce noise levels even further. The effects of employing the various silencing techniques are indicated in tables in chapter Accessories. Temperature Atlas Copco air motors can operate reliably in ambient temperatures that range from C ( F) to + C (+10 F). However, below ambient temperatures of + C (+1 F) the compressed air may need to be dried to avoid freezing problems. Please note it is often possible to operate these motors at much higher temperatures but this should not be attempted without first checking with your local Atlas Copco representative. Hostile environments M 1 M Atlas Copco air motors are found in use in many hostile environments, often with little or no modification. These environments are typified as being: bar 7 psi n1 n Figure Speed Acidic Explosive Radioactive High temperature Moist Dusty Intense electric fields Underwater High humidity. It is also possible to power an air motor with many types of compressed gas, for example nitrogen or natural gas. However, to ensure safe and reliable service, we recommend you always consult your local Atlas Copco representative before using an air motor in a hostile environment. Starting torque and stall torque Many applications demand that a motor produces a minimum torque at start-up. In these a minimum starting torque, for a given motor, can be looked up in the tabular data. If it is necessary to modify the motor s, but also maintain a high starting torque, the technique of throttling the air flow should be utilized. Atlas Copco Air motor Selection Program The Atlas Copco Air Motor Selection Program makes it very easy for you to select the right motor. The Windows-based program stores data on all Atlas Copco air motors. Simply specify the required torque and speed of the motor and the program will select the most suitable motor for your application. Available at ATLAS COPCO AIR MOTORS

10 INSTALLING YOUR AIR MOTOR Air lines The recommended dimensions of air lines are given in the introductory section to each motor type. Note that exhaust hose is larger than inlet hose. The recommendations are valid for hose lengths of up to meters. For distances between and 1 meters select a hose diameter one size up, and for distances between 1 and 0 meters select a hose diameter two sizes up. It is important to note that the of the motor will be reduced if these guidelines are not followed. Recommended hose connectors Because of the compact dimensions of Atlas Copco vane motors, special hose connectors are available with small key width facilitating easy installation. The hose connectors can be ordered through your local Atlas Copco representative. Air preparation For optimum performance and maximum machine life we recommend the use of compressed air with a maximum dew point of + C. We also recommend the installation of an Atlas Copco refrigeration-type air dryer. To ensure reliable service an air filter and lubricator should be fitted into the inlet air line within meters from the motor. It is recommended that a pressure regulator is also incorporated into the air preparation package. This has the function of maintaining the desired working pressure, and can be used to modify the motor s to meet the needs of the application. When selecting an air preparation package, ensure all components have sufficient flow capacity to meet the requirements of the motor. The filter shall remove solid particles larger than 1 microns and also remove more than 0 % of liquid water. A typical arrangement of an air preparation installation is shown below, Figure. Lubrication Lubricated vane motors To achieve optimum service life and performance the lubricated vane motors should be used. They should be supplied with 0 mm of oil for each cubic meter (00 liters) of consumed air (one oil drop 1 mm ). Insufficient lubrication will result in accelerated vane wear and performance reduction. The following example shows how to calculate the lubrication required for a motor running at a known working point. Example: A Non-reversible LZB motor running imum consumes 1 liters/sec of air. In one minute it consumes 7 liters of air, therefore the lubrication required is: 7 x 0 = mm /min 00 If an oil-fog lubricator is to be used it should be set to deliver drops of oil a minute (1 drop = 1 mm ). The selected lubrication oil, should have a viscosity between - mm /s at the motor s working temperature. In applications where there is a risk of insufficient or un reliable air lubrication, we recommend using a lubrication free vane motor. The table below shows how reduced lubrication can affect service life and power for a lubricated vane motor. Lubricant quantity mm oil m Service life Hours Output power % drop of oil is approx. 1 mm A = Filter B = Pressure regulator C = Oil fog lubricatior Figure Lubrication free vane motors Atlas Copco s LZB vane motors up to LZB and LZB stainless steel are available with lubrication free vanes as standard, for the bigger LZB models lubrication free kits are available. If running a motor with 0% dry air and no lubrication, performance can be reduced by -1%. depending on model. Free speed will be more affected, reduced by -%. To optimize the service intervals for a lubrication free vane motor, use lubricated air if the application allows it. ATLAS COPCO AIR MOTORS

11 Directional control valves These valves are used to start or stop a motor, or to change its direction of rotation. It is most usual to use what is termed a / valve to control a reversible motor, and a / valve to control a Non-reversible motor. The valve designations refer to the number of connection ports and the number of operating positions the valve provides, for a / valve this is -connection ports and positions. When selecting any control valve it is important to ensure that it has a sufficient flow capacity to supply the requirements of the motor. Installation examples Typical installation diagrams for type LZB and LZL air motors, together with their associated control valves, filters, regulators lubricators and silencers. / valve / valve Figure The symbols used to represent these valves in an installation diagram. NOTE: For LZL air motors it is important that an inlet restrictor is placed upstream from the inlet. It must be placed so it does not affect the exhaust at reversible running. This means that it has to be placed before the control valve.

12 INTRODUCTION TO AIR MOTORS AND GEAR UNITS LZB Vane motors 0.1 to. Type LZB Atlas Copco vane motors are compact in design, light in weight, and available with a host of different gear ratios to meet a variety of speed and torque requirements. They are particularly suitable for building into handheld machines, or indeed any industrial equipment. Planetary gear units Atlas Copco planetary gear units are particularly suitable for use with LZB vane motors. The gear and motor components can be accommodated within a single, extremely compact housing where they provide high torque capacity for their size and exceptional efficiency, Figure. Stainless steel air motors Atlas Copco s stainless steel motors enlarge the field of applications to areas where the environment is corrosive. This can be in the food processing industries where corrosive detergents are used or in the chemical industry where the atmosphere as such is corrosive. Atlas Copco s stainless steel motors have a clean design. Their smooth surfaces are cylindrical with no pockets where dirt can collect. The motors are easy to clean. The motors have double seals in Viton at the shaft to prevent dirt and liquids from entering the motor gears. The seals also prevent the gear lubricant from leaking out. All external parts, including the shaft, are made of stainless steel. The grease in the motor complies with NSF H1 and FDA 1CFR For applications where there might be moisture in the compressed air the stainless steel LZB-motors can be equipped with a stainless steel motor cell as an option. With this option the motor becomes 0% stainless, both internal and external. Explosion proof All our air motors are explosion proof certified for fixtured applications, in compliance with the European Union s ATEX directive 1//EU. For equipment used in potentially explosive environments. The LZL motors with Helical gears are not ATEX certified. EX-Certified air motors are ideal in hazardous environments where sparks or high outer temperatures might otherwise ignite explosive gases, vapour or dust. Figure See Explosion prevention guideline and the ATEX key, how to read the ATEX code, at the end of the catalogue. 1 ATLAS COPCO AIR MOTORS

13 Lubrication free air motors Atlas Copco s lubrication free air motors are equipped with low-friction vanes, sealed bearings and vented cylinder plates. Since they release no lubricants into the air, they offer a viable drive solution for sensitive processes and hygienic environments where oil contamination would be at best a problem and, at worst, a catastrophe. Both lubrication free vanes and lubricated vanes are available as kits for replacement or conversion. LZL vane motors to. Type LZL Atlas Copco vane motors have been designed to offer outstanding starting and low speed performance. These general purpose motors are powerful, rugged and hard wearing, Figure. Silicon free All the air motors are 0% silicon free. For applications handling paint, this is an absolute must as the presence of silicone can cause big problems. LZB high torque low speed air motors Achieving high torques generally calls for very large motors with correspondingly high air consumption. The LZB high torque/low speed air motors are based on the combination of LZB, the workhorse in Atlas Copco s air motor program, and the gears used in the large LZB- motors. This gives a compact motor/gear package. The gears are dimensioned to stand being loaded at full stall torque indefinitely. Competing low speed air motors often have to limit their torques to prevent gear breakage. Helical gear units Figure Atlas Copco helical gear units are normally fitted to Type LZL vane motors. Standard units are highly efficient, providing speeds of 00 down to 17 and torque up to 0. The gear unit is connected to the motor with IEC flange, Figure 11. LZB-LR, LZB-LR and LZB-RL-LR low speed air motors When there is a need for low speed and low torque, LR motors offer a complete and low price solution compared to the high torque LZB air motors. 000 Figure Motors with brake The most popular vane motors, LZB,,, are available with parking brake. This brake is located between the motor and the gear. It is a disc brake that is spring activated when the motor is not running. When the motor is started the brake is released by a built-in pneumatic piston. The brake is used when it is important that the shaft must not turn when the motor isn t running and a torque is applied on the shaft.

72 LZL VANE MOTORS Introduction LZL vane motors are available in five sizes, offering s of, 1.,.,. and., respectively. They are designed to give outstanding starting and low speed performance. This is achieved by using a six vane motor and by optimum vane/cylinder sealing obtained through a combination of vane air and interconnecting pins. Featuring few components, these motors are ruggedly constructed and offer a long service life. Figure 1 1. Six vanes for high starting torque.. Pins to force vanes out and provide starting reliability.. Cast iron housing.. Long life bearings.. Restriction at inlet and outlet ports. 7 ATLAS COPCO AIR MOTORS

73 Shaft loading The permitted radial and axial shaft extension loadings are illustrated in Figure. These values have been calculated for shaft and bearing working lives of at least 00 hours at a speed that gives maximum. Restrictors LZL vane motors are supplied with internal restrictors in the connection ports, to limit the maximum speed. Clockwise rotation the smaller restrictor (1) is fitted in the inlet port and the larger restrictor () in the outlet port (see Figure ). This is how the motor is delivered. Anti-clockwise rotation the position of these restrictors must be reversed. Reversing duty restrictor (1) must be replaced by a second restrictor of type (). The restrictor (1) must then be fitted into the inlet to the control valve. For further information, see page 11 chapter Installation Examples. It is permissible to remove these restrictors to increase motor. However, the motor should not be run faster than max allowed speed (see data table). Mounting LZL vane motors may be mounted in any position. To facilitate this, a flange is integrated into the motor casing and a foot mounting is available for some motor variants. Connection and hose dimensions Information on connection size and recommended nipple and hose dimensions for use with LZL vane motors is shown in Table. These dimensions are valid for hose lengths up to m. For lengths above m, choose a hose one size larger.

75 Low to medium speed motors (M) These motors are, among other applications, ideal for mixing. To further ensure a clean and hygienic environment, a double shaft seal is used and all components that come in contact with the mixed medium are made of corrosion-resistant material. Thanks to the cylinder design and highly stable bearings, LZL motors require no extra drive shaft support and are ready for mounting without add-ons. For good adaptability, the motors are available with AC, IEC or NEMA.

78 LZL VANE MOTOR/GEAR UNIT COMBINATIONS Combined with helical gear units, LZL vane motors can be used over a very wide torque and speed range. Gears have a ratio range between.:1 to 1.:1, corresponding to a speed range of 1 to 17 and torque up to 1.. Helical gear units, type BF Helical gear units are available in,, or -stage configurations. They deliver high efficiency levels and are available in a wide choice of ratios, Figure. Calculating sprocket or gearwheel dimensions If it is intended to fit a sprocket, gearwheel or pulley onto the shaft, the radial load generated when running must be within the permitted level. The following formula is used to calculate the minimum diameter of these components, to ensure the radial load does not exceed this limit. D min = x M x kt [m] F where M = load torque in F = permitted radial force halfway along the shaft extension kt = for sprocket 1. for gear wheel 1. for pulley Operating speed To avoid damage to seals the gear units should not be run continuously above 0 rpm. Mounting There are two options of mounting arrangement: Foot or Flange as illustrated in Figure. 1. Foot. Flange Figure Shaft loading The maximum allowable radial load on the shaft of each gear unit, at the halfway point on the shaft can be obtained from the data tables for each model. The maximum permitted axial load is % of the table value for radial load if full permitted radial load is occurring. If there is no radial load the maximum permissible axial load is 0% of the table value for radial force. Temperature Figure The gear units can operate within an ambient temperature range of C ( F) and +0 C ( F). If it is required to use a gear unit outside these temperature limits please consult your local Atlas Copco representative. 7 ATLAS COPCO AIR MOTORS

89 EXPLOSION PREVENTION GUIDELINES ATEX In addition to the product instructions for air motors, the following guidelines apply to explosion protected air motors. Temperatures The maximum surrounding temperature for which the certification is valid is 0 C ( F). 0 C ( F) is also the maximum allowed temperature of the compressed air when it enters the motor. If the motor is installed in a equipment, the entire equipment has to correspond to the guidelines 1//EU. Make sure that the compressed air fulfill our quality demands (quality classes... and.. respectively.. acc. to ISO/DIS 7-1). Do not exceed maximum pressure of. bar, or as stated on the motor nameplate. Exceeding the operating pressure can increase the surface temperature due to higher rotating speed and the motor can become an ignition source. ATLAS COPCO AIR MOTORS
