Product Description:

The MSK101E-0300-FN-M1-BG2-NNNN is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated packaging lines, machine tools, and printing presses, it supplies closed-loop rotary motion with high torque density and precise feedback. Its frame is prepared for coolant circulation, so the motor can sustain continuous duty in installations where open-air cooling is limited. That makes it suitable for axis applications that must maintain accurate speed and position during repeated production cycles.

This motor is engineered for continuous operation under the FN cooling requirement, and its jacket channels support liquid cooling so heat is removed directly from the stator without relying on ambient air. Internally, the motor uses winding code 0300 and has size 101 with length E, which are used for drive matching and mounting clearance planning. Feedback is supplied by an optical encoder that generates 128 signal periods per revolution and transfers position data over the Hiperface interface. The multi-turn absolute design retains position information across multiple shaft revolutions, which avoids a homing routine after power loss. A B-side power connector helps route cables cleanly when the motor is mounted with the connector facing the machine bed, and the feedback channel gives the drive immediate rotor position data for commutation and controlled motion.

An integrated holding brake provides 70 Nm of static torque so vertical or high-inertia axes can remain fixed when power is removed. The motor uses a plain shaft, which supports coupling to gearboxes or belt pulleys without keyed shaft hardware. The housing is rated IP65, helping protect internal components from dust and low-pressure water jets during industrial use. Continuous service is permitted at ambient temperatures of 0–40 °C, and insulation class 155 supports winding temperatures up to 155 °C without degrading the winding system.
