Product Description:

The MSK100B-0300-NN-M2-BP0-RNNN is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it delivers commanded torque and speed to linear tables, pick-and-place heads, or spindle drives, enabling repeatable positioning without mechanical backlash. Integration with Rexroth drive controllers allows closed-loop control over acceleration and deceleration profiles required for high-cycle assembly lines and packaging equipment.

The motor housing dissipates heat through natural convection, eliminating the need for external blowers and reducing cabinet complexity. Rotor and stator alignment use an increased concentricity design that lowers magnetic unbalance and vibration. Feedback to the drive electronics is provided by an EnDat2.1 optical encoder that generates 2048 signal periods per mechanical revolution, and the fine subdivision applied inside the controller produces sub-arc-minute resolution at the load shaft. Because the scanning head records absolute position over multiple revolutions, the encoder uses a multi-turn absolute format, so homing routines are unnecessary after power loss. The winding insulation has a thermal class of 155, supporting continuous service at elevated copper temperatures.

The housing has an IP65 protection rating, blocking dust ingress and water jets during washdown maintenance. The motor operates in ambient temperatures from 0 to 40 °C. Mechanical power is transferred through a shaft with a keyway, while the power connector is located on the B-side to align with standard cable routing in Rexroth drive cabinets. The rotor stack length is coded B, the frame is size 100, and the electromagnetic characteristics follow winding code 0300. The unit is supplied without a holding brake to minimize mass on the shaft.
