Product Description:

The MSK100B-0300-NN-M1-RP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts controlled electrical input from a drive into accurate rotary motion for positioning, indexing, or speed-regulated tasks. This makes it suitable for axes that must start, stop, and reverse with repeatable motion. The model uses a size-100 frame with a B-length stator and a 0300 winding variant, so its electrical characteristics can be matched to a compatible IndraDrive controller.

This motor uses natural convection for cooling, so no external fan or liquid circuit is required and the mounting position must allow free air circulation. Rotor position data are supplied through a Hiperface interface, which sends absolute and incremental feedback to the drive for closed-loop control. The optical scanning head resolves the code disc into 128 signal periods, and the optical measuring principle helps maintain signal quality across the speed range. Because the encoder is a multi-turn absolute design, the drive receives a unique shaft position for up to 4096 revolutions after power cycling, which reduces the need for a reference move when startup resumes.

An electrically released brake provides a holding torque of 32 Nm, helping prevent drift when the axis is de-energized. Power enters the stator through a connector on the right side, which can simplify cable routing when the machine places the cable chain along that side of the motor. Torque is transmitted through a shaft with keyway, allowing keyed couplings to be fitted without extra shaft machining. The motor uses winding code 0300, which corresponds to the electrical values intended for the matching drive rating. This shaft style is often used where the driven element must resist slip under changing load.
