Product Description:

The MSK101C-0300-FN-S1-AP0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion control, it converts drive current into precise rotary movement for indexing tables, gantry axes, and forming presses in automated lines. The integrated feedback channel allows the control system to monitor torque, position, and thermal status in real time, which helps the drive correct motion deviations as operating conditions change. It supports direct flange mounting and fits applications that require high continuous torque with low maintenance.

The motor’s stator casing is prepared for liquid cooling, so circulating coolant absorbs losses and helps maintain winding temperature under high load. Position feedback is delivered through a Hiperface interface that combines incremental and absolute data streams for coordinated servo control. Inside the feedback unit, an optical scanner produces 128 signal periods per mechanical turn, which the drive interpolates for fine position control. Because the sensor is a single-turn type, absolute angle information is retained within one revolution. The motor is supplied without a holding brake, so external holding methods are required when the load must remain fixed at standstill.

Electromagnetic behavior is set by winding code 0300, which matches the phase resistance and inductance to standard IndraDrive current ratings. Power is transmitted through a shaft with a keyway, allowing connection to gears or pulleys without a custom hub and helping resist slip under cyclic loading. The frame size 101 with the C length variant balances torque capacity with installation depth for medium-to-large axis assemblies. All power conductors exit on the A-side, which can simplify cable routing in layouts where the cabinet runs parallel to the motor axis. This arrangement keeps the connection point on one end of the motor and can reduce cable crossover in linear machine layouts.
