Product Description:

The MSK100B-0300-NN-S3-BP0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop rotary motion for positioning and velocity control tasks in automated machinery, packaging lines, and material-handling axes. When paired with a compatible drive controller, the unit converts electrical commands into torque with high precision, allowing compact actuator stages without mechanical gearing.

Cooling is by natural convection, so heat leaves the stator surface without auxiliary fans and surrounding airflow must remain unobstructed. The housing carries an IP65 rating that protects the windings against dust ingress and low-pressure water jets. A shaft with keyway permits positive torque transfer to pulleys or couplings, while the motor is delivered without a holding brake, so external locking devices are required when power is removed. Electrical power arrives on the rear B-side connector. For feedback, the integrated encoder reports position through the Hiperface protocol at a resolution of 16 signal periods per revolution, allowing the drive to interpolate fine motion steps.

The winding set uses code 0300, matching the impedance profile expected by compatible IndraDrive amplifiers. Frame size 100 and length designation B set the overall mechanical envelope and inertia class, helping with coupling and mounting selection. Thermal endurance is supported by insulation class 155, permitting continuous conductor temperatures above common ambient conditions. Normal operation is permitted at ambient temperatures from 0-40 °C, and higher temperatures require derating or forced ventilation. The motor uses capacitive sensing within its single-turn encoder to provide stable absolute feedback without optical components.
