Product Description:

The MSK075E-0450-FN-S1-UG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts controlled three-phase drive power into precise rotary motion for positioning axes, pick-and-place heads, and packaging spindles within automated machinery. The standard housing uses the 075 frame with an E-length stator, yielding high continuous torque while keeping the overall length suitable for tight machine layouts. Its plain output shaft allows direct coupling to gearboxes, timing pulleys, or belt drives.

Its thermal management relies on liquid cooling, where a coolant circuit removes heat directly from the stator laminations and keeps winding temperature lower than in similar air-cooled units. Position feedback is supplied by a rotatable 240° connector that carries a Hiperface serial link from an optical encoder in the rear housing. The sensor delivers 128 signal periods per revolution, providing fine commutation data. Because the encoder is of the single-turn type, it reports absolute position within one mechanical turn and simplifies homing routines after power loss. The motor is delivered without a holding brake, so the machine must use external clamping or controller torque to hold the load.

The enclosure meets the IP65 rating, preventing dust ingress and resisting nozzle-directed water so the unit can be mounted outside control cabinets. A plain shaft configuration eliminates keyways and favors shrink-fit couplings that reduce backlash. Electrical insulation conforms to class 155, and the permitted ambient temperature range is 0 to 40 °C. The stator uses winding code 0450, which indicates the conductor gauge and turns count used for nominal voltage and current pairing with IndraDrive controllers. The sealed housing supports installation on machine surfaces that are exposed to dust and washdown spray.
