Product Description:

The MSK050C-0450-NN-M1-UP1-NSNN synchronous servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It uses a size 050 frame with a C-length stator, giving a compact form that fits closely spaced machine axes without sacrificing servo performance. This configuration is suited to packaging, material handling, and processing equipment that requires accurate torque production, repeatable positioning, and smooth speed regulation. Its compact format is useful on machine sections where adjacent actuators, guards, and product tooling leave limited clearance around the motor body. The motor is intended for dynamic axis duties such as indexing, conveying, metering, and synchronized transfer movements where fast response and stable control behavior are important throughout repeated operating cycles.

Cooling is handled by natural convection, so the motor does not require an external blower and can operate within an ambient range of 0-40 °C. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal components when the motor is mounted near wet process areas or washdown equipment. Position data come from an optical multi-turn absolute encoder with 128 signal periods per mechanical turn and Hiperface transmission, giving the connected drive the information needed for accurate closed-loop motion control. The feedback connection uses a rotatable, 240° connector, which helps route cables cleanly in tight spaces and reduces strain at the plug during installation. Absolute feedback also helps the drive retain position information after a power cycle.

A holding brake provides 6 Nm of static torque, allowing the motor to support vertical loads or maintain position when drive power is removed. This brake function is useful on lifting and Z-axis applications where gravity can move the load after shutdown. The output uses a shaft with keyway, which supports direct coupling to pulleys, pinions, or gearboxes without requiring a special clamping hub. Winding code 0450 identifies the electrical configuration used for this motor and matches the parameters expected by compatible drive controllers. Insulation class 155 allows elevated winding temperatures during dynamic duty while maintaining reliable thermal performance during repeated acceleration, deceleration, and holding periods.
