Product Description:

The MSK100B-0400-NN-M1-BG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion axes that need high torque density and accurate feedback in packaging, material-handling, and machining equipment. The motor follows a standard design and comes without a holding brake, so it is suited to systems that hold position through drive torque or external clamps. Position feedback is delivered by a multi-turn absolute encoder that communicates shaft angle directly to the drive controller for precise positioning and continuous position tracking across multiple revolutions.

Thermal energy is removed by natural convection, so the housing relies on ambient airflow rather than external blowers. The motor body carries an IP65 rating that prevents dust ingress and protects against water jets. Command and feedback are exchanged through the Hiperface interface, and the optical transducer provides 128 signal periods per revolution for fine speed and position control. The electromagnetic circuit uses winding code 0400, which matches IndraDrive amplifiers for medium-current applications and supports stable operation on dynamic servo axes.

A plain shaft allows couplings or timing pulleys to seat without keyways, which can help reduce vibration in high-speed assemblies. Continuous service is supported between 0–40 °C, and insulation class 155 allows the winding to tolerate elevated internal temperatures during normal operation. The stator frame size is 100 with a length code of B, giving the motor a balanced combination of inertia and torque for mid-range servo axes. A power connector mounted on the B-side keeps the cable exit away from the encoder end, which helps separate power and feedback routing in compact machine layouts.
