Product Description:

The MSK100A-0450-NN-S1-BG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary servo unit, it delivers precise position and speed control for presses, packaging stations, and other CNC axes in automated lines. The motor couples directly to drive controllers through its integrated feedback interface, enabling closed-loop regulation without external encoders. This arrangement supports accurate motion on axes that require repeatable starts, stops, and speed changes during automatic operation under changing loads.

Thermal management relies on natural convection, so heat is dissipated through the frame without forced airflow. Position feedback is supplied through a Hiperface encoder that communicates absolute data to the drive. Inside the feedback unit, the disc generates 128 signal periods per mechanical revolution, and the scanning head uses optical sensing for high-resolution signal capture. The electromagnetic package uses motor size 100, which identifies the stator diameter and mounting pattern in the MSK line. This frame format supports compact integration on machine axes that need direct motor mounting.

The encoder operates in a single-turn configuration, reporting absolute rotor angle over one revolution without multi-turn counting; this suits axes that home at power-up. The unit is supplied without a holding brake, so external holding force is required when power is removed. Power and protective earth conductors attach on the B-side of the housing, which helps route cables away from the load shaft. The motor uses winding code 0450, which matches it to compatible current and voltage characteristics in the drive. Additional mechanical characteristics include a plain output shaft, motor length A for the shortest stack in the 100-frame group, and a standard housing that follows MSK mounting conventions.
