Product Description:

The MSK101E-0300-NN-M2-BG0-RNNN is a synchronous servomotor from Bosch Rexroth Indramat that sits within the MSK IndraDyn S Synchronous Motors series. Designed for precision motion stages, packaging axes, and general factory automation, this motor converts electrical energy into tightly regulated mechanical rotation. Bosch Rexroth classifies it as a synchronous servomotor intended to work with IndraDrive controllers, where its electronic feedback and mechanical tolerances support accurate positioning, speed control, and repeatability across demanding industrial duty cycles.

Feedback accuracy is centered on an optical measuring system that generates 2048 signal periods per mechanical revolution; coupled with its EnDat2.1 digital interface, the drive obtains absolute multi-turn position data without needing homing moves. The rotor-mounted sensor conforms to a multi-turn absolute format, allowing the controller to read the shaft angle even after power loss. A 101 frame diameter gives the stator sufficient space for copper fill while keeping inertia moderate for dynamic axes, and the motor’s axial build is identified by length code E, which extends stack height for higher continuous torque. A plain shaft transmits torque directly, and the unit is supplied without a holding brake, so external means must secure the load when power is removed.

The mechanical core follows an increased concentricity design to minimize radial runout, improving coupling life in high-precision machinery. Thermal management relies on natural convection, so installation must allow free airflow around the housing rather than forced cooling. Electrical characteristics are linked to winding group 0300, which sets the resistance and inductance values expected by the paired inverter. Power and feedback cabling exit on the B-side, which keeps both cable paths on one face of the machine when space is limited.
