Product Description:

The MSM031C-0300-NN-M5-ML0 is a compact synchronous motor developed by Bosch Rexroth Indramat for integration into the MSM IndraDyn S Synchronous Motors series. It acts as a rotary actuator that converts electrical energy into controlled mechanical motion within packaging, assembly, and pick-and-place stations. By delivering consistent torque and position accuracy, the unit interfaces directly with IndraDrive controllers, allowing parameter-based speed regulation and coordinated multi-axis movement in industrial automation lines. Its design favors small-footprint machinery where high dynamic response and minimal maintenance are important.

At standstill, the rotor can maintain a continuous torque of 1.30 Nm, providing steady force for holding or low-speed indexing tasks without overheating. The specified cooling mode is natural convection, so airflow around the housing must remain unobstructed rather than relying on fans or liquid circuits. The motor length is C, which indicates the axial dimension used with matching gearheads and mounting flanges. Frame designation 031 identifies the external diameter category and shaft height used by other motors in this size group. Electrical characteristics correspond to the segment-specific winding code 0300, which is associated with the phase resistance and inductance values used by the matching drive controller for stable current control.

The motor is supplied without a holding brake, so the axis relies on servo control or mechanical clamps to prevent motion after power is removed. This omission reduces weight and rotor inertia, which suits the compact 031 frame and supports quick cycle changes. Load back-drive tendencies should be considered, and external locking may be needed where gravity or process forces act during dwell periods, especially in vertical or overhung installations.
