Product Description:

The MSK050C-0300-NN-S3-UP0-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks where the drive regulates torque, speed, and position with consistent response. This standard-design unit has frame size 050 and frame length C, and it uses a shaft with a keyway to simplify powertrain coupling. Its synchronous design allows the motor to respond quickly to commanded changes from the servo drive during acceleration, deceleration, and positioning. Winding code 0300 sets the electrical characteristics used with compatible IndraDrive controllers. It is supplied without a holding brake, so position at standstill must be maintained by mechanical clamping or motor torque.

Cooling is handled by natural convection, eliminating the need for forced-air or liquid-cooling hardware. The integrated encoder uses a rotatable 240° plug, so the cable exit can be aligned with cabinet or drag-chain layouts. Position feedback is transferred over the Hiperface protocol, and the encoder provides 16 signal periods per mechanical revolution for commutation. The sensing principle is capacitive, which helps resist interference from oil mist and magnetic fields during operation. This arrangement supports stable feedback transmission while keeping cable routing flexible in compact machine layouts.

Because the encoder is single-turn, the motor reports absolute position within one revolution, and the drive tracks additional turns electronically. The housing carries an IP65 rating, which blocks dust ingress and low-pressure water jets so the unit can be mounted outside control cabinets when needed. The sealed housing also helps protect internal components when the motor is installed near moving mechanical assemblies. Continuous duty is permitted at ambient temperatures from 0 to 40 °C. Thermal insulation class 155 allows elevated winding temperatures before aging accelerates, which helps the motor handle intermittent overloads while maintaining expected service life. This temperature range is typical for enclosed machinery and general industrial environments.
