Product Description:

The MSK050B-0300-NN-S3-UP0-NNNN is an AC synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Deployed inside automated cells, the unit couples with a drive to deliver tightly regulated torque and position, letting packaging mandrels, small machining axes, or electronic assembly stations follow commanded motion profiles with minimal error. This type of motor is intended for closed-loop servo applications where the controller must correct speed and position continuously during operation. The motor uses size code 050, so the frame remains compact enough for space-restricted machines while still supporting the acceleration demands typical of multi-axis production lines. Because it is built for precision motion, it is suitable for indexing tasks, short travel moves, and repeatable cycle timing on automated equipment.

This motor relies on natural convection for heat removal, so thermal energy leaves the housing without auxiliary fans or liquid circuits. Feedback is supplied through a Hiperface interface that communicates rotor position digitally to the drive, allowing the control loop to track shaft movement during startup and motion. Inside the encoder, a capacitive scanning system forms the measuring element, the feedback provides 16 signal periods, and the position data are organized as a single-turn value referenced within one mechanical revolution. Digital feedback also helps the drive maintain commutation accuracy at low speed and during rapid direction changes. The motor has a standard design and is supplied without a holding brake, so any power-off holding force must come from external mechanics or drive torque.

A wiring plug on the stator is rotatable through 240°, allowing the cable exit to match the cabinet layout and avoid sharp bends. This adjustable connector position can help keep the cable away from neighboring machine parts in tight installations. Power is transmitted through a shaft with a keyway, which supports coupling to timing pulleys or rigid hubs that require positive torque transfer. The keyed output also supports connections that need fixed angular alignment between the motor and the driven element. Motor length B keeps the housing relatively short while preserving the inertia level needed for responsive axis movement.
