Product Description:

The MSK101D-0450-FN-M2-AG0-RNNN is a servo motor in the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As a compact direct-drive element, it converts drive-controller output into rotational motion for positioning tasks in automated machinery, conveyors, and process lines where accurate speed and angle control are required. It is intended for use with a compatible servo drive that manages current, speed, and position loops during machine operation. The motor’s D length and 101 frame size provide a balanced footprint versus torque capacity, making the unit suitable for medium-inertia axes that need quick response without external gearing and controlled motion in limited installation space.

Thermal management relies on liquid cooling, enabling continuous current without fan noise, and the 0450 winding is matched to that cooling arrangement. Position data are reported over the EnDat 2.1 interface by an encoder that delivers 2048 signal periods per revolution, and its optical scanning principle minimizes quantization error. Because the sensor is multi-turn absolute, the axis retains position through power cycles, eliminating homing routines. Increased concentricity in the rotor-stator fit helps reduce cogging, and power is connected on the A side for compact cable routing. The motor is supplied without a holding brake, so static load retention must be provided externally.

The housing is sealed to IP65, resisting dust ingress and water jets in typical machine areas. Reliable operation is specified at ambient temperatures from 0 to 40 °C without derating. A plain shaft simplifies mechanical coupling where keyways are unnecessary, and that shaft style is often used with clamping hubs or other friction-locking couplings. The thermal system is matched to insulation class 155, allowing winding temperatures up to 155 °C. The liquid jacket helps keep vibration low, and service wiring remains accessible on the A-side connector for tight panel layouts.
