Product Description:

The MSK071E-0202-NN-S3-UG0-NPNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor is intended for closed-loop motion stages, feeders, and other automation axes that require high positional accuracy and stable speed regulation. When paired with an IndraDrive controller, it converts electrical energy into precisely metered torque, allowing machinery to index, follow electronic cams, or synchronize with conveyor lines.

The housing is cooled by natural convection, so heat leaves the stator through its surface without fans or liquid circuits. A mounting face with flange assembly (B5) allows the motor to bolt directly to gearboxes or machine frames while keeping the shaft center concentric. Feedback is transmitted through a Hiperface digital link, which carries both position data and electronic nameplate data to the drive. Inside the encoder, rotor movement is subdivided into 16 signal periods. After interpolation by the control electronics, this supports fine step commands and low velocity ripple. Position sensing relies on capacitive measuring cells, an architecture that is immune to magnetic stray fields and remains accurate despite temperature changes.

The encoder delivers absolute values in a single-turn format, so the controller knows rotor position within one revolution at power-up. The motor is sealed to IP65, blocking dust ingress and water jets when the cable junction is fitted correctly. Continuous operation is permitted from 0 to 40 °C, and the insulation materials meet class 155 limits for the windings. The motor uses a plain shaft without keys, and the 071 frame size with E-length establishes the magnetic package. Winding code 0202 corresponds to the voltage and current constants, the connector can rotate 240°, and the unit is supplied without a holding brake to keep inertia low on dynamic axes.
