Product Description:

The MSK030B-0900-NN-S3-UP0-NNNN servomotor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As a compact permanent-magnet rotor unit, it converts drive controller output into precise rotary motion for positioning axes, pick-and-place heads, or small conveyor stations in industrial automation and similar motion-control equipment. Its B-length housing and 030 frame size balance torque capacity against mass, making it suited for agile duty cycles. The model is supplied without a holding brake, so external locking mechanisms or residual drive torque must secure the load when power is removed.

Heat is removed only by natural convection, so installation must allow free airflow around the finned aluminum housing. The enclosure carries an IP65 rating, which prevents dust ingress and resists low-pressure water jets that could reach the windings or the class 155 insulation system. A 240° rotatable encoder connector simplifies cable routing in tight cabinets and maintains sealing during rotation. Feedback is exchanged through the Hiperface protocol, letting the drive read absolute position and electronic nameplate data over a single hybrid cable. Inside the encoder, resolution is fixed at 16 signal periods, which the drive interpolates into fine incremental counts; the 0900 winding code sets the corresponding voltage constant and rated torque.

The sensing core relies on capacitive scanning rather than optical disks, so contamination has minimal effect on accuracy. Because the tracker is single-turn, absolute position information spans one mechanical revolution, and multi-turn values must be derived at the controller. The motor can run continuously within an ambient range of 0 to 40 °C, so it is intended for moderate surrounding temperatures. The motor uses a shaft with keyway, which assures slip-free torque transfer to pulleys or couplings and supports repeatable mechanical zeroing during service.
