Product Description:

The MSK050C-0450-NN-S1-UP0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive current into accurately metered rotary motion that positions indexing mechanisms, grippers, and feeder rolls in automated lines where cycle-time precision is mandatory. The motor’s medium-frame format targets machines that demand fast acceleration without sacrificing installation space.

The housing relies on natural convection, so heat leaves the stator through surface radiation and ambient airflow, allowing mounting where cabinet cooling is limited. Frame code 050 sets the flange and shaft geometry for this size class. Inside the feedback stack, an optical scanning system couples an incremental disk to a sinusoidal interpolator, and the resulting digital position data are exported through the Hiperface interface for connection to compatible controllers. Resolution is specified at 128 signal periods, which supports tight velocity loops during low-speed contouring. The standard mechanical design does not require specialized seals or liquid-cooling plates.

The shaft end is machined as a shaft with a keyway, supplying positive torque transmission to pulleys or couplings without relying only on clamping forces. Single-turn feedback is confirmed by the single-turn encoder turn type, meaning one mechanical revolution corresponds to the full digital count before the signal resets. Electrical termination is handled through a connector that is rotatable through 240°, so the plug can be positioned to clear neighboring components. The stator winding group identified by code 0450 matches drives that deliver the rated current envelope for this model. Motor length C keeps overall depth short, and the unit is supplied without a holding brake, so mechanical stops or drive torque must secure the load when power is off.
