Product Description:

Bosch Rexroth Indramat manufactures the MSK050C-0450-NN-M1-UP1-NNNN servomotor within the MSK IndraDyn S Synchronous Motors series. This motor converts drive current into precise angular motion for positioning tasks in industrial automation. In closed-loop axes, it provides the rotary output needed for indexing, feed movement, and repeatable positioning in packaging, handling, and assembly equipment. The unit follows the standard design format, carries motor size 050 and length C, and integrates a rotatable 240° encoder connector that lets feedback cabling be routed to suit tight control-cabinet layouts. The connector position can also be adjusted to reduce cable strain where nearby machine structures leave limited clearance around the motor.

Cooling is handled by natural convection, so heat leaves the housing through passive airflow and surface dissipation without fans. Because no fan is required, the motor keeps a sealed outer surface without forced-air openings. The enclosure has an IP65 rating, blocking dust ingress and water jets so the motor can be mounted directly on exposed machine frames. An electrically released holding brake supplies 6 Nm of static torque to secure vertical or suspended loads during power loss. Position feedback travels through the Hiperface digital link, enabling the drive to read identification data and encoder values over the same cable. Inside the optical encoder, tracks generate 128 signal periods, providing high-resolution incremental data that improves velocity regulation at low speeds.

Further feedback capability comes from its multi-turn absolute design, which stores multiple shaft revolutions and reports an exact position immediately after power is restored, eliminating homing cycles. Continuous operation is specified for ambient temperatures between 0–40 °C, matching the passive cooling method to typical factory conditions. Torque reaches the load through a shaft with a keyway, a mechanical interface that helps prevent slip during rapid reversals. Insulation class 155 tolerates winding temperatures up to 155 °C, supporting service life when the winding code 0450 is driven near rated limits.
