Product Description:

The MSK071E-0200-NN-M2-UG1-RNNN is a synchronous servomotor from Bosch Rexroth Indramat that belongs to the MSK IndraDyn S Synchronous Motors series. As an AC servo element, it converts controller commands into precise rotary motion for positioning and speed-regulated tasks in automated machinery. The unit uses motor size 071 with length code E, and winding code 0200 is matched for use with drive modules in the IndraDrive platform. Increased concentricity in the mechanical design supports low vibration, and a rotatable 240° connector simplifies encoder cable routing inside the machine.

In this model, heat is removed through natural convection, so installation must allow free airflow around the housing. Position feedback is handled by an optical encoder that communicates through the EnDat2.1 protocol, and the interface provides absolute position data without extra calibration cycles. Internal scanning produces 2048 signal periods per mechanical revolution, and the encoder uses a multi-turn absolute design that retains position information across power cycles for up to 4096 turns. Motion is secured when power is off by an electrically released holding brake, and its rated torque of 23 Nm keeps vertical axes or rotary index tables in place without external clamps.

The enclosure has an IP65 rating, which seals the motor against dust ingress and water jets found on typical factory floors. A plain shaft without a keyway minimizes radial runout and supports the use of clamp collars or shrink disks in tight mounting spaces. Reliable operation is specified within an ambient range of 0 to 40 °C, so forced cooling is not required as long as the surrounding air stays within that limit. The windings use insulation class 155, which provides thermal headroom during cyclic peak loading without reducing insulation life.
