Product Description:

The MSK101E-0300-FN-M2-BG2-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed-controlled motion, where commanded current is converted into precise torque for packaging stations, gantry axes, and similar automated equipment. Integrated feedback lets the matching drive monitor rotor movement directly, which supports accurate motion control during repeated start, stop, and holding sequences. The compact housing also allows the motor to mount directly on machine frames, which helps keep cable routing short and supports dense machine layouts.

Thermal management relies on liquid cooling, which carries heat away through the stator jacket during continuous high-load operation. Position data are transmitted through the EnDat2.1 interface by an optical multi-turn absolute encoder with 2048 signal periods, giving the drive fine feedback information for interpolation and stable control at low and changing speeds. An electrically released holding brake provides 70 Nm of static torque so vertical axes can remain in place when power is removed. The housing is rated IP65, which helps keep dust and low-pressure water jets away from internal components in typical industrial environments.

The motor uses thermal class 155 insulation and is intended for ambient temperatures from 0 to 40 °C without derating. A plain shaft supports direct coupling to backlash-free clamping hubs, which is useful where low runout and accurate torque transfer are required. The frame size of 101 places the unit in a larger motor format suited to applications that need substantial output while still fitting within standard servo mounting layouts. Power connections exit on the B-side, and the motor must remain connected to the machine's liquid circuit whenever it operates so cooling performance stays consistent during sustained duty.
