Product Description:

The MSK070C-0300-NN-M1-UP1-NSNN synchronous servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is used in industrial automation to drive axes that demand precise velocity, torque, and position control, integrating directly with servo drives in packaging cells, material-handling stations, and CNC machinery. The motor supports closed-loop motion tasks where stable response is needed during acceleration, steady running, and accurate stopping. In these applications, it converts commanded electrical input into controlled rotary motion for the connected machine axis.

This motor relies on natural convection, so heat is removed through its housing without external fans or liquid circuits. Its housing carries a protection rating of IP65, which shields internal windings and the encoder from dust ingress and low-pressure water jets. Continuous operation is permitted within an ambient range of 0 to 40 °C; outside that window, output must be derated or additional cooling must be provided. The frame size is 070, while length code C balances torque capability against installation depth. Coil variant 0300 identifies the electrical resistance and inductance selected for this size, allowing the paired drive controller to supply current without saturation. Class 155 insulation tolerates winding temperatures up to 155 °C, and the design supports explosion-protected configurations for hazardous locations.

Position feedback is handled by an optical multi-turn absolute encoder that communicates over Hiperface. Its internal scale provides 128 signal periods, giving the drive fine interpolation for smooth speed loops and stable low-speed control. The encoder connector can be rotated through 240° to simplify cable routing in tight cabinets and crowded machine layouts. An electrically released holding brake is integrated; it supplies 23 Nm of static torque to secure vertical loads when power is removed. The mechanical interface is a shaft with a keyway, enabling positive torque transmission to pulleys or couplings and helping the motor fit standard industrial drive arrangements.
