MSK100A-0300-NN-S3-BP0-NNNN

The MSK100A-0300-NN-S3-BP0-NNNN is a synchronous servomotor developed by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts electrical energy into controlled rotary motion for position, velocity, and torque tasks common in packaging lines, gantry axes, and automated tooling. Integration with IndraDrive controllers lets the motor act as a compact, brushless actuator that maintains tight feedback loops in industrial automation settings.

Thermal management relies on natural convection, so mounting space must allow unobstructed air circulation instead of forced cooling devices. Position feedback is provided by a capacitive measuring system coupled to a Hiperface interface, enabling digital transmission of rotor angle and diagnostic data to the drive. The encoder resolves one mechanical revolution into 16 signal periods; the drive interpolates these periods for fine velocity control. Because the feedback is singleturn, absolute position is retained only within one turn, making the motor suitable for axes that reference at startup but do not require multi-turn tracking. This feedback combination reduces cabling complexity because power and data share a common hybrid connector.

Mechanical dimensions fall under motor length A and the 100 frame size, giving a moderate flange square that matches typical machine layouts. The electromagnetic circuit is defined by winding code 0300, which pairs the stator resistance and inductance with IndraDrive power stages intended for medium current ranges. Service wiring is simplified because the power connector sits on the B-Side, allowing parallel cable routing when several motors are installed on the same axis rail. Rotary power is transferred through a shaft with keyway, so couplings or pulleys can lock axially without relying on friction. The design is standard, and the unit is supplied without a holding brake, so external brakes or drive torque must secure the load when power is removed.
