Product Description:

The MSM031C-0300-NN-M5-MH0 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. This compact unit is intended for general industrial automation where precise rotary motion and a small footprint are required. Its brushless design allows it to pair with IndraDrive controllers and deliver position or speed control to indexing tables, pick-and-place heads, and light-duty actuators on packaging or electronics assembly lines. It can be used in machines that need smooth starts, accurate stops, and reliable speed regulation through repeated operating cycles.

At standstill the motor can deliver a continuous torque of 1.30 Nm, so it can hold a steady load at zero speed within its thermal capability. Heat is removed through natural convection, which means the housing should remain exposed to ambient air instead of depending on an external fan or tightly enclosed mounting surfaces. With Motor Size 031 and a body length of C, the motor stays compact while still providing room for the active stator length used in this frame. Its 0300 winding code sets the electrical characteristics expected by the matched drive and helps keep motor and controller behavior aligned during closed-loop operation.

The motor is supplied without a holding brake, so a vertical or suspended load must be secured by drive torque or by an external locking device when power is removed. It uses a plain shaft, which is commonly paired with a clamping hub or other friction-based coupling. Because there is no shaft seal, the motor should be installed where liquid ingress is not expected and where the shaft area can remain clean during operation. Low rotor inertia helps the axis accelerate and decelerate quickly in short-cycle applications such as indexing and light transfer motion.
