Product Description:

The MSK100B-0300-NN-M1-BG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an electromechanical actuator, it converts commanded drive current into precise rotary motion for positioning or velocity-regulated axes in industrial automation lines, packaging machines, and material-handling systems. The housing follows a standard design, so no liquid cooling provisions are included. In closed-loop systems, the motor works with a matching drive to maintain commanded speed and position as load conditions change during machine operation.

This model releases waste heat through natural convection, so it can be mounted without external blowers as long as ambient airflow is available. Position feedback is supplied through a Hiperface interface that carries both power and serial data between the encoder and the drive. Inside the motor, the optical encoder provides 128 signal periods per mechanical revolution, and its light-based scanning method offers high signal fidelity over long operating periods. Because the sensing package is a multi-turn absolute type, it retains shaft position across power cycles, eliminating homing moves at startup. The winding code 0300 sets the electrical values matched to compatible IndraDrive amplifiers in medium-torque ranges.

The unit is supplied without a holding brake, so any static load must be secured by the drive or an external clamp when power is removed. Motor length code B balances inertia and continuous torque, while frame size 100 gives a 100 mm stator diameter for compatibility with gearboxes and couplings in the same power class. Power and feedback cabling exit on the B-side, simplifying wiring in cabinets laid out with right-hand cable trays. A plain shaft is fitted so the user can select shrink-fit or keyed hubs as needed. The motor is intended for tightly controlled positioning duties where mechanical holding torque is furnished externally during stops or power-off conditions.
