Product Description:
The MSK101D-0300-NN-S2-LG2-RNNN is built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor supplies closed-loop torque and speed so that drive controllers can position axes with repeatable accuracy during packaging, metal-cutting, or material-handling cycles. Its synchronous design supports smooth acceleration, controlled deceleration, and stable speed regulation during repeated motion sequences. The 0300 winding code aligns the motor's electrical characteristics with compatible IndraDrive supplies.
The unit cools through natural convection, meaning heat leaves the housing without fans or liquid circuits, so clear airflow around the frame is required. Position feedback travels over the EnDat2.1 serial interface, allowing high-resolution data exchange between the optical encoder and the drive. That encoder resolves motion into 2048 signal periods, and the drive can multiply these periods electronically for fine incremental positioning. An electrically released brake supplies 70 Nm of static torque, keeping vertical or suspended loads from drifting when power is removed. The enclosure meets the IP65 rating, excluding dust and low-pressure water jets so the motor can mount close to process equipment without added covers. Motor size 101 with length code D provides substantial torque capacity while keeping the overall footprint suitable for compact machine layouts, and the plain shaft simplifies coupling to gearboxes or belt pulleys.
The encoder uses optical scanning for low noise and stable phase signals, and its single-turn design reports one mechanical revolution for applications that home on startup. Thermal class 155 permits winding temperatures up to 155 °C, and the motor must remain in ambient temperatures from 0 to 40 °C. Power enters through a left-side connector so cable trays can be routed along that edge of the machine. Increased concentricity in the rotor design limits radial runout, which helps maintain smooth rotation at the shaft.
