Product Description:

The MSM031C-0300-NN-M0-CH1 is a synchronous motor produced by Bosch Rexroth Indramat in the MSM IndraDyn S Synchronous Motors series. In automated equipment, it supplies torque and position feedback so servo drives can keep machine axes on programmed motion paths during positioning and speed-controlled tasks. The motor is intended for compact servo-driven axes that need controlled acceleration, repeatable stopping, and stable feedback through short production cycles. Its small housing suits pick-and-place units, indexing tables, and feeder modules where installation space is limited but responsive motion is still required.

The motor delivers a continuous standstill torque of 1.30 Nm, which is the load it can sustain at zero speed during continuous operation. Heat is removed by natural convection, so the motor does not require an external fan or liquid cooling circuit. Rotor position is tracked by a multiturn absolute encoder that reports shaft position over multiple revolutions, which allows the axis to retain position information after a power interruption instead of returning to a reference point. Power and feedback conductors leave through a cable tail for direct routing into moving cable systems, and the motor uses frame size 031 for compact mounting in dense assemblies.

The holding brake uses electrical release and provides 1.27 Nm of static torque to keep vertical or suspended loads in place when power is off. A plain shaft allows connection to couplings, gearheads, or pulleys in applications where a simple shaft interface is suitable, and the lack of a shaft seal helps reduce friction in clean, dry environments. Winding code 0300 sets the electrical characteristics for matching speed and current behavior with compatible drive modules, and the installed brake allows the axis to remain fixed after motor power is removed.
