Product Description:

The MSK071D-0300-NN-M2-UG0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque-generating element in closed-loop motion axes, it converts commanded current from an IndraDrive into controlled mechanical rotation for positioning, packaging, and material-handling equipment. Increased concentricity in the mechanical design reduces radial runout, which helps maintain consistent coupling alignment during continuous operation.

The motor is cooled by natural convection, so heat leaves the housing through free airflow without auxiliary fans or liquid circuits. Its internal feedback device is optical, using light-based scanning to track rotor movement with high signal fidelity even when vibration levels change. Feedback accuracy is enhanced by a native resolution of 2048 signal periods per revolution, and the drive electronics interpolate these periods to generate fine incremental counts for velocity control. Position data and diagnostics travel through the EnDat2.1 interface, enabling synchronous serial communication and automatic electronic nameplate reading. Size 071 and length D indicate the stator stack and overall depth, helping the motor fit established machine layouts with limited installation space.

The encoder is multiturn absolute, meaning it records shaft location across 4,096 mechanical revolutions without battery backup, so homing cycles are unnecessary after power loss. Wiring exits through a connector rotatable through 240°, allowing cable routing around nearby machine hardware. Output torque is transferred through a plain shaft, which has no keyway, so balanced clamp couplings should be used to protect the motor bearings. The unit is supplied without a holding brake, so static load retention must be provided by the drive or an external brake module. Winding code 0300 corresponds to the voltage constant and rated current used by the paired drive.
