Product Description:

The MSK100B-0300-NN-M3-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It serves as the mechanical output element in closed-loop industrial drive systems, translating regulated stator currents from an IndraDrive controller into tightly controlled torque. Typical tasks include tracking motion profiles on multi-axis gantries, regulating feed rolls in printing lines, or maintaining synchronized spindle speeds. Its electrical commutation and integrated feedback support repeatable positioning accuracy under varying loads and changing acceleration demands.

The unit relies on natural convection for thermal dissipation, so installation must allow unobstructed airflow around the housing during continuous operation. Electrical power is supplied through a connector on the B-side, which helps parallel motor mounting and reduces cable bend conflicts near the machine frame. With a frame size of 100 mm, the motor uses the matching stator diameter, while length code B increases active core length to raise continuous torque without changing the mounting footprint. Internal copper distribution follows winding code 0300, which sets the motor’s voltage constant and current requirements for the paired drive.

A plain shaft transfers torque through friction-fit or keyed couplings, and the stator end bell includes a Hiperface interface that sends position data to the drive. The measuring system is capacitive and is resistant to magnetic stray fields, while multi-turn absolute feedback with 16 signal periods per revolution lets the controller retain position information through power cycles without a homing move. Because the motor is supplied without a holding brake, external restraints must secure vertical loads when power is removed. The housing uses a standard design intended for applications that do not require forced ventilation or an integrated brake.
