Product Description:

Bosch Rexroth Indramat manufactures the MSK050B-0450-NN-S2-UG0-RNNN synchronous servo motor, which belongs to the MSK IndraDyn S Synchronous Motors series. The unit supplies controlled torque and precise angular positioning to axes in packaging, material-handling, and automated assembly machinery. It converts electrical commands from a compatible drive into controlled rotary motion, allowing stable speed control and accurate positioning during repeated machine cycles. This makes the motor suitable for coordinated axis movements where repeatable response and smooth motion are required throughout normal production duty.

The motor relies on natural convection for thermal management, so the 050 frame dissipates heat through its housing surface without fans or coolant circuits. Its mechanical build features increased concentricity, which helps limit shaft runout and supports alignment with precision gearboxes or direct-coupled mechanisms. A wiring advantage comes from the feedback plug, which is rotatable 240° so cable orientation can be adjusted to suit cabinet and machine layouts. Position data are transmitted through the EnDat2.1 serial interface, and the encoder provides 2048 signal periods per revolution for precise motion feedback. The sensing principle is optical, which helps maintain stable feedback performance in applications where stray magnetic fields may be present. Together, these features support consistent feedback quality during low-speed control, interpolation, and direction changes.

Additional feedback characteristics include a single-turn design, so absolute position is retained within one mechanical turn without battery backup. The rotor uses a plain shaft, allowing direct coupling with clamping hubs or bell housings where low backlash is preferred. Winding code 0450 indicates the electrical characteristics assigned to this length-B motor for use with a compatible drive. The motor is supplied without a holding brake, so any load-holding function must be provided by the drive or by external locking hardware. Its compact 050 size also helps it fit into multi-axis machines where installation space is limited.
