Product Description:

The MSK030B-0900-NN-M1-UG1-NSNN is a synchronous servomotor developed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated assembly cells, pick-and-place gantries, and compact packaging modules, this motor converts drive-controller commands into tightly regulated rotary motion that maintains position accuracy over repeated duty cycles. It is intended for servo-driven axes that require accurate speed regulation, repeatable positioning, and stable response during starts, stops, and short indexing moves. Its plain shaft couples directly to gearheads or cylinders. By integrating encoder, power, and mechanical functions in one housing, the unit supports compact axis layouts and simplifies installation.

The housing meets the IP65 protection rating, sealing the windings against dust and low-pressure water jets so the motor can be mounted outside control cabinets. Heat produced by copper losses leaves the frame through natural convection, eliminating the need for external fans. Closed-loop control is handled through the Hiperface serial interface, which carries position data and sensor power over the same cable. The optical feedback system provides 128 signal periods per revolution for fine incremental interpolation. For static holding, an electrically released brake supplies 1 Nm of torque to lock the shaft when the supply is disabled.

The encoder uses a multi-turn absolute function, so the stored position remains available after shutdown without a homing cycle. Thermal endurance follows insulation class 155, permitting continuous operation near the upper winding temperature limit. The permitted ambient range is 0 to 40 °C, which matches typical factory conditions for convection-cooled equipment. Winding code 0900 corresponds to the electrical characteristics used in size 030, length B frames. A rotatable 240° connector also helps with cable routing where surrounding machine space is limited.
