Product Description:

The MSK100B-0200-NN-M1-BP2-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a servomotor, it converts electrical energy into precise rotary motion for industrial automation axes that require closed-loop speed and position control. The motor falls within the manufacturer’s size-100 frame class and is supplied in length code B, which suits machinery layouts that require this housing length.

This motor is cooled by natural convection, so heat leaves the housing through surface radiation and airflow without external fans or liquid circuits. For positional feedback, the stator incorporates a Hiperface interface that transmits absolute position data to the drive over two bidirectional conductors, simplifying cabling. The optical scale inside the encoder yields 128 signal periods per mechanical revolution, allowing the drive controller to generate high-resolution counts for smooth velocity loops. Motion can be held during power loss because an electrically released brake supplies 70 Nm of static torque directly on the shaft. The frame code of 100 indicates the centering diameter and bolt pattern used when the motor is mounted to gearboxes or machine plates.

The feedback device relies on optical scanning to track rotor position, giving immunity to magnetic cross-talk that may occur near large inductive loads. Its sensing disc is a multiturn absolute type, so the controller receives a unique revolution count without needing a homing sequence after shutdowns. Mechanical power is delivered through a shaft with a keyway, enabling straightforward torque transmission to keyed hubs or couplings. All power conductors exit on the motor’s B-side, which helps keep encoder and power wiring physically separated. The winding code 0200 and the standard mechanical design suit general-purpose servo axes where passive cooling and absolute feedback are preferred.
