Product Description:

The MSK070E-0300-NN-S3-UP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion control, the unit converts regulated drive current into precise rotary movement for packaging axes, pick-and-place gantries, and indexing tables in automated factories. Its standard construction and 070 frame size provide a compact actuator for machine layouts where mounting space is limited. A keyed shaft allows direct coupling to pulleys, gearboxes, or other driven elements while maintaining repeatable torque transfer and accurate positioning during multi-axis operation.

Heat generated in operation leaves the stator through natural convection, so no auxiliary fan or liquid circuit is required. Feedback is routed through a rotatable 240° connector that supports the Hiperface protocol, allowing the drive controller to exchange position data and read motor information at startup. The embedded encoder produces 16 signal periods per mechanical turn and uses a capacitive sensing element that is less sensitive to contamination than optical disks. Because the encoder is single-turn, it reports an absolute angle within one revolution, while the control system tracks additional turns during continuous motion. This arrangement supports accurate commutation and stable position control in applications with frequent starts, stops, and direction changes.

An electrically released brake delivers 23 Nm of static holding torque, permitting load retention during power loss or emergency stop events. The housing carries an IP65 rating, which protects the windings and bearings against dust ingress and low-pressure water jets. Rated service conditions cover ambient temperatures from 0 to 40 °C, and Class 155 insulation allows the winding pack to withstand elevated thermal loads without premature aging. The brake is useful when the axis must remain in place after the drive is disabled. These operating limits suit enclosed machinery that requires dependable holding force, sealed motor surfaces, and consistent thermal performance under normal industrial conditions.
