Product Description:

The MSK071C-0300-NN-S3-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy from a drive controller into regulated torque and speed for positioning axes, packaging systems, and other precision-motion tasks in automated machinery. Its compact dimensions and electronic commutation support closed-loop motion control in equipment where accurate response, repeatable movement, and stable speed regulation are required.

Heat is removed through natural convection, so the motor does not require an external fan or liquid cooling circuit. An enclosure rating of IP65 helps protect the housing against dust and low-pressure water jets in industrial settings. Position feedback is transmitted over the Hiperface interface, and the encoder plug is rotatable, 240° to improve cable routing where space is limited. A capacitive, single-turn sensor provides 16 signal periods of absolute and incremental feedback data for the drive. Mechanical output is delivered through a shaft with keyway, which helps prevent coupling slip under cyclic loads. The motor uses the standard construction of the series, matching common mounting flanges and bolt-circle arrangements.

The frame code 071 with length designation C gives the motor its overall footprint and continuous-torque range, while winding code 0300 identifies the electrical values used by the matching drive. Insulation class 155 supports sustained winding temperatures during demanding duty cycles without damaging the insulation system. The permitted ambient range is 0–40°C, and operation above that range requires derating or additional cooling. The motor is supplied without a holding brake, so vertical or suspended loads require external locking or active motor torque when power is removed.
