Product Description:

The MSK061C-0300-NN-S2-UP1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts electrical power into tightly regulated rotary motion for servo axes in packaging stations, assembly robots, and metal-cutting machines. By combining high torque density with integrated feedback, the motor supports dynamic positioning cycles while maintaining accuracy across a wide speed range. Its operating concept suits applications that require repeatable starts, stops, and short indexing moves.

The unit relies on natural convection for thermal management, so surrounding airflow must carry heat away from the aluminum housing. Mechanical accuracy is improved by a design with better concentricity, which helps reduce radial runout at the shaft during precise motion. Feedback passes through a rotatable 240° connector, making cable routing easier in confined machine layouts. The feedback system uses the EnDat2.1 interface and an encoder with 2048 signal periods per revolution to send absolute position data to the drive. The sensing element uses optical scanning in a single-turn configuration, so one absolute position value is available for each mechanical revolution. For load holding or emergency stops, an electrically released brake provides 10 Nm of static torque. The stator uses winding code 0300 for compatibility with matching drive settings.

The motor has an IP65 protection rating, which seals it against dust ingress and low-pressure water jets. Continuous operation is permitted within an ambient range of 0 to 40 °C, which suits standard machine-room conditions. Power is transmitted through a shaft with a keyway, which supports positive torque transfer to couplings, pulleys, and gearboxes. The motor uses frame size 061 with length code C, giving it a predictable mounting footprint. The windings use insulation class 155, allowing elevated internal temperatures without insulation breakdown.
