Linear unit selection Irrespectively of the configuration requested, it always starts selecting the proper linear unit. To do so, the first 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 Load Draw an horizontal line on the Calculate the expected travelled LEMC lifetime curve distance for the application t each intersection of this line with the linear units lifetime curves, draw vertical lines Select the LEMC size corresponding to the L 10 distance required Calculate the Dynamic load carrying capacity (C a ) required Select the LEMC 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 LEMCx10 LEMCx110 LEMCx00 LEMCx010 Screw type Roller screw Roller screw Roller screw Roller screw Screw diameter d mm 1 1 0 0 Screw lead P mm 10 10 Max. axial force 1) F max kn 0 0 80 80 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 00 1 000 0 880 Max. rotational speed ω max rpm 6 000 6 000 80 80 Max. acceleration a max m/s 6 1 6 1 Stroke ) s mm 100 to 600 100 to 600 100 to 800 100 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 IPS IPS IPS 1) uckling limitation for long stroke ) y 100 mm step ) For LEMC1: +0,1E0 kgm by 100 mm stroke step For LEMC0: +0,6E0 kgm by 100 mm stroke step

This is the axial force, constant in magnitude and direction, under which the nominal life (as defined by ISO) reaches 1 million revolutions. 7 L 10, distance C a = F m P 10 6 Lead L 10, distance = N cycles Stroke Cubic mean load Load F 1 LEMC with servomotor The LEMC can be ordered with servomotor. In the latter case, SKF has selected a series of motors and drives that fits 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 LEMC with the brand of servomotor of your choice to integrate best in your system. Please contact SKF to check the feasibility of your configuration. 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 configurations. If you can t find a configuration that fits your application performance wise, please contact SKF.

www.lmotion.ru lmotionmail@ya.ru.: (9)9160 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 configuration 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 LEMC can be offered with or without the servo drive, with the servo drive corresponding to the one in the advised configuration or any other that would fit 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. LEMC with asynchronous motor The LEMC with asynchronous motor is in fact the combination of a LEMC 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 configurations. The gearboxes are oil lubricated. When ordering a LEMC with asynchronous motor, it is therefore important to indicate the proper configuration 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: Linear 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 Less wiring thanks to electronic contactor and motor protection function Excellent energy efficiency 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 configuration, please contact SKF. Example table 1.
