Product Description:

The MSK071E-0300-FN-S2-UG0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This IndraDyn S servomotor is used in industrial automation systems where fast position control and repeatable torque are required for packaging lines, gantry axes, and machine tools. By pairing with a compatible Rexroth drive, the motor converts command currents into regulated mechanical rotation, forming the actuation element in a closed-loop motion axis.

The stator winding uses code 0300 and is built on the 071 frame, while the E length provides an extended stack for higher torque density. Heat generated by the copper is removed through liquid cooling, so continuous load can be sustained without derating. The rotor uses increased-concentricity machining to minimize runout at the plain shaft interface. Feedback is delivered by an encoder with a 240° rotatable plug to simplify cable routing. The device transmits position data over the EnDat2.1 interface, with an internal resolution of 2048 signal periods provided by the optical scanning head. The motor is supplied without a holding brake, so axis holding torque must be furnished by the drive or an external clamp.

For service duty, the encoder operates as a single-turn device, supplying absolute position for one motor revolution, which fits most short-stroke axes and simplifies homing routines. The housing is rated IP65, and sealed joints plus shaft seals prevent dust or low-pressure water jets from reaching internal parts. The electrical insulation uses class 155 materials, supporting winding temperatures associated with continuous servo peaks enabled by the liquid cooling circuit. The unit can be installed where ambient air remains within 0–40 °C. This ambient range supports normal motor operation.
