Product Description:

Bosch Rexroth Indramat manufactures the MSK100D-0300-NN-M1-BP0-NNNN, a member of the MSK IndraDyn S Synchronous Motors series. This servomotor converts electrical energy into tightly regulated rotary motion for positioning tasks across packaging stations, machining centers, and material-handling axes in industrial automation. In closed-loop operation, it works with a compatible drive to support accurate speed regulation, fast acceleration, and repeatable positioning under changing loads. Its standardized mechanical envelope and integrated feedback options allow it to fit multi-axis platforms that require high dynamic response and consistent motion control.

Cooling is based on natural convection, so the motor dissipates heat through its housing fins without external fans and can be installed where airflow is limited. Rotor position and speed are transmitted over a Hiperface interface for bidirectional data exchange with the drive controller. The optical sensor delivers 128 signal periods, giving fine angular resolution for smooth velocity loops. Because the scanning principle is optical, neither Hall elements nor magnetoresistive strips are required, which helps reduce sensitivity to electrical noise. This feedback arrangement supports stable low-speed control and consistent position reporting during frequent starts and stops. The encoder stores absolute position across power cycles, yet the unit is supplied without a holding brake, so external holding means are required when the load must remain fixed at standstill.

The feedback system uses a multi-turn absolute mechanism, enabling the drive to recover shaft angle after power restoration without homing routines. Mechanical power is delivered through a shaft with a keyway, which eases coupling to pulleys or gearboxes that rely on positive torque transfer. This shaft form also supports output connections that need secure mechanical engagement during repeated acceleration and deceleration. The power connector is mounted on the B-side, which supports routing motor leads parallel to adjacent axes in compact machine layouts. The motor uses winding code 0300, which matches the current and torque characteristics of the 100 mm frame and D-length stack used in this design.
