The Lenze MCS series of synchronous servo motors has been uprated by up to 60% by the addition of an axial blower.  Increased cooling airflow permits the continuous ratings to be increase.  Previously the range covered from 0.5 to 51Nm rated torque (0.25 to 10kW).  The new models increase the maximum torque to 72Nm and power to 15.8kW.

The breadth of the MCS motor range allows rightsized selections where the motor speed and inertia can be optimally matched to the load.  There are 34 models without blower (IP54 or IP65 enclosure) and a further 20 new models with blower and a protection class that remains at IP54.

MCS synchronous servo motors are known for their small dimensions with a very even delivery of torque, particularly at low speeds.  This is a result of the SEpT Single Element Pole Technology which creates a high density uniform field of magnetic flux.  Cogging torques are virtually imperceptible. Other features include an optional electronic nameplate chip for faster drive configuration and new quick-fit connectors that need only ? turn to fix.

These Lenze servo motors are easy to select and use with brake and encoder options, also pre-assembled Lenze system cables.  Approvals include CE, GOST and cURus.  The addition of axial blowers has extended the range without increasing the motor sizes and provides a very economical solution for high performance servo drives.
