2 ElectroMechanical Cylinder EMC enefits High eficiency ong service life from use of SKF planetary roller screw Compact and robust structural design Modular concept with multiple combinations and options vailable for all motor brands Smart and freely programmable drive system Depending upon your choice, the EMC cylinder can be ordered in several ways: 1 simple linear unit, linear unit with motor interface, inline or parallel, to install the motor of your choice (eventually with a reduction ratio), complete actuator including the linear unit, motor interface as well as the servomotor and corresponding drive, complete actuator including the linear unit, motor interface, gear reductor and an asynchronous motor. inear unit selection Irrespectively of the coniguration requested, it always starts selecting the proper linear unit. To do so, the irst step is to calculate the mean load the linear unit will be subjected to and then follow the steps described next. Please not that in the general case, the maximum operating load should not exceed 80% of the capacity (C a ) of the screw. Calculate the cubic mean oad Draw an horizontal line on the Calculate the expected travelled EMC lifetime curve distance for the application t each intersection of this line with the linear units lifetime curves, draw vertical lines Select the EMC size corresponding to the 10 distance required Calculate the Dynamic load carrying capacity (C a ) required Select the EMC size corresponding to the C a required Verify that additional performance requirements such as linear speed, stroke are compatible with the Eventually proceed to motor selection Technical data Unit EMCx10 EMCx110 EMCx00 EMCx010 Screw type Roller screw Roller screw Roller screw Roller screw Screw diameter d mm Screw lead P mm Max. axial force 1) F max kn Max. input torque for F max T max Nm 1,7 8, 87,1 161, Dynamic load carrying capacity C a kn 0,, 91,9 106, Max. linear speed V max mm/s Max. rotational speed ω max rpm Max. acceleration a max m/s Stroke ) s mm 100 to to to to 800 Internal over stroke s o mm Inertia for stroke 0 ) J EMC kgm 1,E0 1,E0,00E0,00E0 acklash s ap mm 0,0 0,0 0,0 0,0 Type of protection IPS / IP6S ) IPS / IP6S ) IPS / IP6S ) IPS / IP6S ) 1) uckling limitation for long stroke ) y 100 mm step ) For EMC1: +0,1E0 kgm by 100 mm stroke step For EMC0: +0,6E0 kgm by 100 mm stroke step ) IP 6S when air ilter port is equipped with a breather tube connected to a non contaminated dry area

3 With: EMC ifetime curve Cubic mean load This is the hypothetical load, constant in magnitude and direction, that would have the same inluence on the actuator life as the actual loading condition. 7 F F + F + F m = P F min + F max F m = F m [N] EMCx010 EMCx00 EMCx110 EMCx dist = asic life rating [10 6 mm] Dynamic load carrying capacity (C a ) This is used to compute fatigue life of rolling element (bearings, screws). This is the axial force, constant in magnitude and direction, under which the nominal life (as deined by ISO) reaches 1 million revolutions. 7 10, distance C a = F m P 10 6 ead 10, distance = N cycles Stroke Cubic mean load oad F 1 EMC with servomotor The EMC can be ordered with servomotor. In the latter case, SKF has selected a series of motors and drives that its best the performance of the actuator to the end user application. To complete the design, several options can be selected such as absolute encoder (EnDat, Hyperface), safety brake or associated servodrive. Depending on your preferences, it is however possible to equip the EMC with the brand of servomotor of your choice to integrate best in your system. Please contact SKF to check the feasibility of your coniguration. Motor selection Once the selection of the mechanical unit size corresponding to your application is done, the next step is to select the motor size and the type of mounting. The listed motor reference is only a part of the possible conigurations. If you can t ind a coniguration that its your application performance wise, please contact SKF.

4 With: Calculate the Thermal force, F thermal Calculate the Nominal force, F nominal Calculate the maximum speed, V max Following the linear unit selected ( page ) and the type of motor mounting, chose a motor/drive coniguration that respects the below conditions: F nominal (selected) > F nominal (calculated) F peak (selected) > F peak (application) V max (selected) > V max (application) Maximum speed (V max ) The maximum speed is the highest value reached by the application during operation. Peak force (F peak ) The peak force is the is the maximum load that could be used during a short time. Thermal force (F thermal ) The thermal force represents the equivalent thermal load the motor has to sustain during a cycle. To calculate Fthermal, it is therefore very important to consider also the resting time during the working cycles. 7 F 1 t 1 + F t + F t + F thermal = P t 1 + t + t + Drive options The performances shown in the table above are the result of a certain servo motor and drive combinations. The EMC can be offered with or without the servo drive, with the servo drive corresponding to the one in the advised coniguration or any other that would it your installation. In the case of a different combination, please contact SKF to check the effect of the different choice on the performance of the actuator. EMC with asynchronous motor The EMC with asynchronous motor is in fact the combination of a EMC linear unit, a gearbox and a smart asynchronous motor. The gearboxes are available with several ratios to either favor speed or load for any linear unit size and from packaging point of view, in parallel and right angle conigurations. The gearboxes are oil lubricated. When ordering a EMC with asynchronous motor, it is therefore important to indicate the proper coniguration so that the drains and vents are located correctly. Smart functions The asynchronous motor are equipped with a smart control box with the following features: inear speed that can be adjusted freely between 00 and 600 r/min digital inputs for changing speed and direction of movement 1 digital output for status message Integrated ramps for soft start and stop functions, to protect the system mechanics and full motor protection ess wiring thanks to electronic contactor and motor protection function Excellent energy eficiency Can be operated with an NFCcapable smartphone Nominal force (F nominal ) The nominal force is the force that can be used continuously at low speed (less than 1% of the maximum speed). F thermal F nominal = 0,7 Parameters like acceleration or inertia are not taken into account in this calculation. In the case of high dynamic cycles, or for an optimized coniguration, please contact SKF. Example table 1.
