Product Description:

The MSK101E-0450-FN-S1-BG0-NNNN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts electrical energy into controlled mechanical motion for positioning or velocity tasks in automated machinery and production cells. Because the motor is supplied without a holding brake, load retention during power-off must be provided by the mechanical system or by drive torque.

Its cooling circuit uses liquid cooling, which removes stator heat through a closed fluid jacket so continuous torque can be delivered without relying on cabinet airflow. A Hiperface-compatible optical encoder is mounted at the rear, and the Hiperface interface allows bidirectional parameter exchange with the drive controller. The sensor generates 128 signal periods per mechanical revolution, giving fine position feedback for accurate interpolation. Single-turn tracking provides absolute position data within one revolution. The motor housing meets the sealing level of IP65, blocking dust ingress and water jets during wash-down cycles. Operation is permitted at ambient temperatures from 0–40 °C, so external cooling water must be adjusted to keep winding temperature rise below the insulation limit. Connectors for power are placed on the B-side of the stator, and the overall mechanical form follows the standard design option for this frame.

The motor size is 101 with length code E, giving it a longer active core than shorter versions in the same platform. Torque is transferred through a plain shaft, so coupling alignment is important because no keyway or serration is provided. The motor uses winding code 0450, which matches the electrical values expected by compatible IndraDrive controllers. Thermal endurance is based on insulation class 155, so the stator windings can tolerate elevated operating temperature within the insulation system limits.
