Product Description:
Bosch Rexroth Indramat manufactures the MSK075E-0300-NN-S2-UG0-RNNN in the MSK IndraDyn S Synchronous Motors series. The motor converts drive commands into accurate rotary motion for conveyors, pick-and-place arms, and other positioning tasks. Its 075 frame and E-length stator provide a compact envelope while still supporting the torque needs of medium-duty industrial axes. When paired with a compatible drive, it supports precise speed regulation and repeatable positioning in automated equipment. That combination suits packaging stations, indexing units, and transfer systems that require responsive servo control without a large motor body.
The motor is designed for direct machine mounting and transfers heat through the housing during operation. Cooling relies on natural convection, so no fans or liquid circuits are required. The enclosure carries an IP65 rating, blocking dust ingress and low-pressure water jets during washdown cycles. Operation is permitted from 0–40 °C, and the windings use thermal class 155 insulation for elevated internal temperatures. Bosch Rexroth applies increased concentricity machining to the fit surfaces, which helps reduce shaft runout and vibration in precision motion systems. This passive cooling arrangement keeps the exterior simple and avoids auxiliary airflow hardware around the axis.
The encoder connector is rotatable 240°, allowing cable routing in the preferred direction inside tight enclosures. Inside the housing, an EnDat2.1 optical encoder supplies single-turn position data with 2048 signal periods per revolution for accurate commutation and interpolation. The output uses a plain shaft, which simplifies coupling alignment and avoids keyway stress concentrations in high-cycle systems. The feedback system gives the connected controller continuous rotor-angle information for stable speed control and accurate positioning during cyclic motion. The motor is supplied without a holding brake, so static load retention must be provided by the drive or by external mechanics.
