Product Description:

The MSK070C-0300-NN-M2-UG0-RSNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as a compact drive component that converts controlled stator current into torque and speed for industrial axes. This supports accurate closed-loop positioning in packaging, printing, and material-handling equipment where repeatable motion is required. The motor is suited to applications that need precise starts, stops, and speed changes without sacrificing smooth rotary operation.

The motor relies on natural convection for heat removal, so it can be mounted without external blowers when ambient air can circulate freely around the housing. Its feedback is handled through the EnDat2.1 interface, delivered by an optical encoder that provides 2048 signal periods per revolution, which allows fine motion resolution after interpolation. The encoder uses a multi-turn absolute design, so shaft angle and full-turn count are retained after power loss and the axis does not require a homing cycle at startup. With an enclosure rating of IP65, the motor resists dust ingress and directed water jets, which supports installation directly on the machine frame.

The motor uses a plain shaft, allowing direct coupling through friction or clamp hubs without keys. Its housing is size 070, which suits medium-torque duties in a compact footprint. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and insulation class 155 allows winding temperatures up to 155 °C. Power and feedback connections can be swiveled through 240° to simplify cable routing in tight spaces. The motor has length code C and winding code 0300, and it is supplied without a holding brake. The design also notes increased concentricity and certified explosion protection for hazardous zones.
