Product Description:

The MSK050C-0450-NN-S3-UP0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed as a compact rotary actuator, it supplies controlled torque and speed to positioning tables, pick-and-place arms, and packaging spindles that rely on closed-loop servo drives. Frame size 050 and length code C establish its physical dimensions, while a keyed shaft provides positive mechanical engagement with couplings or gearboxes used on industrial machines. It is intended for machinery that depends on consistent response to drive commands, especially where axis motion must remain synchronized with sensors, product flow, or upstream control logic.

Thermal management is provided by natural convection, so heat dissipates through the housing without external fans or liquid circuits. The enclosure meets IP65, which helps keep dust out and protects internal parts against water jets. Position feedback is handled through a Hiperface interface that communicates absolute angle data to the drive. Inside the encoder, a capacitive scanning method resists magnetic contamination, and the measuring system is single-turn, supplying an unambiguous position within one motor revolution. Electrical hookup is simplified because the encoder connector is rotatable through 240°, allowing the cable outlet to be aligned to suit the machine layout.

The feedback unit provides 16 signal periods, giving the controller a repeatable angular reference for electronic commutation and stable speed regulation. This servo motor is supplied without a holding brake, so any static load must be held by the drive or by external mechanical means when power is removed. Continuous operation is permitted in ambient air from 0–40 °C, which suits typical industrial indoor environments. Insulation class 155 supports elevated internal winding temperatures during sustained duty. Because the feedback system reports absolute position within one revolution, the paired drive can establish commutation quickly after startup and maintain smooth low-speed behavior during short indexing moves. This makes the motor suitable for repetitive motion tasks that alternate between acceleration, dwell, and deceleration under servo control.
