Product Description:

The MSK070C-0300-NN-S1-UG0-NNC3 is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Supplied as an IndraDyn S servomotor, it converts drive current into precise rotary motion for positioning axes, packaging machines, and general automation lines. Its synchronous design supports responsive speed and position control when used with a compatible servo drive. This model’s part number identifies its frame size, winding, and feedback option, which helps distinguish it from other motors in the same family.

Heat is removed by natural convection, so no external fan or coolant lines are required. That cooling method leaves the housing free of auxiliary hardware and supports installations where cable space is limited around the axis. The 070 frame uses a plain shaft for direct coupling, while motor length C and winding code 0300 indicate the motor’s active stack and electrical setup. A rotatable 240° encoder connector eases cable routing in cramped panels. Position data travel through the Hiperface interface, and the feedback system provides 128 signal periods. Because the measuring principle is optical, the feedback remains stable through long-term thermal cycling. The encoder is supplied without a holding brake.

This feedback is a single-turn design, so the drive receives absolute position within one motor revolution and handles turn counting beyond that range. The enclosure has an IP65 rating that blocks dust ingress and water jets, allowing installation on machinery cleaned with spray hoses. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which suits typical indoor industrial conditions. The windings use insulation class 155 to tolerate sustained internal heating and preserve dielectric strength over time.
