The water-cooled SIMOTICS M-1FE built-in motors are used in combination with the SINAMICS S120 drive system for applications that require the highest quality of machining, accuracy and running smoothness, as well as very short ramp-up times.

There are two main versions of SIMOTICS M-1FE built-in motor available:

• High Torque series
  6-pole/8-pole and 16-pole synchronous motors are available that have been developed for turning and grinding machines with moderate maximum speeds.
  These motors are characterized by a very high torque utilization. In this case, the speed range is approximately 1:2.
• High Speed series
  In this series, 4-pole synchronous motors are available for milling. These motors are optimized for high maximum speeds and a speed range of over 1:4.
