MSM031B-0300-NN-M5-MH0

The MSM031B-0300-NN-M5-MH0 is a compact servo drive motor produced by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. Designed for mid-power axes, it converts electrical energy into rotary motion for indexing tables, pick-and-place heads, and other motion stages where precise position control is required in automated production lines. Its permanent-magnet rotor allows tight speed regulation when paired with IndraDrive controllers, making the unit suitable for applications that demand consistent cycle times and repeatable torque delivery.

At standstill the motor can deliver 0.64 Nm of continuous torque, allowing it to maintain load position without overheating during static phases. Heat generated in this operating state is removed through natural convection, so additional fans or liquid circuits are not required. Coil design is identified by winding code 0300, which defines the resistance and inductance values expected by the compatible drive. With a motor size 031 frame, the housing footprint is small enough for compact machine layouts yet still provides sufficient stator surface area for thermal dissipation. The manufacturing quality of Bosch Rexroth Indramat supports reliable integration alongside other IndraDyn motion components.

Mechanically, the unit follows the dimensional envelope marked as motor length B, establishing overall body depth for stack planning inside a cabinet or on a moving axis. The output shaft is a plain shaft, so torque is transmitted via clamp or friction-fit couplings instead of keyed connections. Because the motor is supplied without a shaft seal, it should be installed in environments where low ingress of coolant or dust at the shaft exit is assured. It is also delivered without a holding brake, meaning position retention during power-off must be handled by the drive or external locking mechanisms. Together, these mechanical choices reduce inertia, simplify maintenance, and keep overall component mass suitable for high dynamic start-stop profiles.
