Product Description:

Bosch Rexroth Indramat manufactures the MSK050B-0450-NN-S3-UG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. The unit is a servo motor that provides precise velocity and position control for packaging lines, handling robots, and material transfer axes. Integrated encoder feedback supplies absolute rotor position to the drive controller, supporting coordinated multi-axis motion in automated cells that demand repeatable cycle times. When paired with a compatible drive, it converts commanded electrical input into controlled rotary motion for synchronized machine functions.

The housing relies on natural convection to dissipate heat, so no fan or coolant manifold needs to be accommodated inside the cabinet. With a sealing level of IP65, dust and low-pressure water jets are kept away from the stator laminations and integral connectors. An electrically released brake supplies 6 Nm of static holding torque for suspended loads and emergency stops. Continuous duty is supported at ambient temperatures from 0–40 °C, preventing thermal derating in normal plant environments. Position and parameter data travel through the Hiperface interface, which combines incremental and absolute signals in a single cable. This model follows the standard design variant of the series and is intended for general industrial motion tasks.

The motor-side feedback plug can rotate through 240°, allowing the cable outlet to clear bulkheads or coolant lines without added adapters. Inside the encoder, a capacitive sensing element produces absolute feedback in a single-turn format with sixteen signal periods, which provides good immunity to magnetic interference. Insulation class 155 permits sustained winding temperatures associated with rapid acceleration profiles. The motor has a plain shaft that couples directly to backlash-optimized couplings. Its B length matches the compact 050 frame, and winding code 0450 sets the motor's electromagnetic characteristics.
