Product description LEMC electric cylinders replace hydraulic systems with a For generations, hydraulic cylinders were often the first precision roller screw, driven by a locally mounted electric choice for large forces or to move heavy loads. Today, hydraulic systems have a powerful rival in the linear motion world – the electric cylinder. In many applications, electromechanical systems provide a host of advantages over their hydraulic counterparts. They are smaller and lighter, and since the motor powering the actuator is connected directly, electromechanical systems do away with bulky...

EWELLIX Motors and gearboxes Servo motors The LEMC can be ordered with a servo motor. In this case, Ewellix has selected a series of Lenze motors and drives that best matches 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. It is also possible to equip the LEMC with your preferred brand of servo motor so that it integrates best into your system. Please contact Ewellix to check the feasibility of your configuration.

High Performance Actuator EWELLIX Asynchronous motors The LEMC with asynchronous motor is the combination of an LEMC linear unit, a gearbox and a Lenze smart asynchronous motor. The gearboxes are available with several ratios to either favor speed or load for any linear unit size. They are available packaged in parallel and right angle configurations. The gearboxes are oil lubricated. When ordering a LEMC with asynchronous motor, the proper configuration must be identified so that the drains and vents are located correctly. Smart functions The asynchronous Lenze motor is equipped with a...
