Product Description:

The MSK030B-0900-NN-M1-UG0-NSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. With a size 030 frame and B-length housing, it offers a compact footprint for machine layouts where installation space is limited. The B-length housing also helps reduce required axial space on compact indexing and transfer axes. In automated machinery, the unit supplies finely regulated torque and speed for coordinated motion tasks on packaging lines, electronics assembly stations, and material-handling axes.

The motor rejects heat through natural convection, so no external fan or liquid circuit is necessary. Cabinet airflow must be sufficient to keep the winding temperature within the limits of the 0900 winding code during continuous operation. Feedback is exchanged over the Hiperface interface through a rotatable 240° connector that simplifies cable routing in tight cabinets. Position feedback comes from an optical encoder that provides 128 signal periods per revolution, and the multiturn mechanism stores up to 4096 shaft turns as a multi-turn absolute value for position retention after power loss. Because the unit is supplied without a holding brake, any static load must be secured by the drive or by an external mechanical lock when power is removed. The 0900 winding code matches the stator resistance and inductance to compatible IndraDrive controllers for rated torque operation.

An enclosure rating of IP65 helps keep dust and low-pressure water jets away from internal components, while the plain shaft supports couplings that use shrink discs or collets instead of keyed interfaces. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which matches typical control-cabinet conditions. Thermal class 155 insulation allows a maximum winding temperature of 155 °C before insulation life is reduced, which supports short-term overloads within the drive's protection range. This motor is suitable for food-processing, printing, and general-purpose automation equipment installed in enclosed, wash-down, or temperature-regulated areas.
