Product Description:

The MSK101E-0300-FN-M2-BG0-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 velocity tasks in industrial automation cells, where precise torque delivery must stay synchronized with drive electronics. When paired with a compatible drive, the motor supports accurate rotary motion on axes that require repeatable speed regulation and position control. Its synchronous design helps the controller maintain stable motion during acceleration, constant-speed travel, and stopping. The motor is used where coordinated movement must remain consistent across repeated machine cycles.

The unit uses liquid cooling, so continuous output can be maintained under high load. A housing sealed to IP65 helps keep dust and low-pressure water jets away from live parts. Rotor position data are transmitted through an EnDat2.1 serial interface from an optical sensor with 2048 signal periods per mechanical revolution. The encoder has multiturn absolute feedback, so the control system can track position over multiple revolutions without a homing cycle after power is restored. The motor is intended for ambient temperatures of 0-40 °C.

The motor has a thermal insulation class of 155, allowing the stator insulation to withstand elevated internal temperatures. It uses a plain shaft for coupling to gearboxes or rigid hubs, and its power leads exit on the B-side to suit common cabinet layouts. The motor does not include a holding brake, so external locking is required when power is removed. Its E-length body and size 101 frame provide a larger active section, while winding code 0300 sets the electrical characteristics expected by the matching drive. The encoder system is integrated into the motor housing, which keeps the feedback path compact.
