Product Description:

The MSM041B-0300-NN-M5-ML1 belongs to the MSM IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact servo unit intended for industrial automation tasks that demand repeatable positioning and stable speed control on small axes such as pick-and-place heads, light conveyors, or indexing tables. Integrated feedback allows the motor and drive to keep machine motion aligned with controller commands. This makes the unit suitable for short travel cycles, frequent starts and stops, and other applications where consistent response is important.

This model produces a continuous standstill torque of 2.40 Nm, so it can hold load while energized without relying on additional gearing in many small-axis applications. Heat generated at that load is dissipated through natural convection, which allows the housing to release heat without a separate fan when ambient airflow is adequate. An internal brake with electrical release remains engaged until power is applied, so the shaft stays secured when the drive is disabled. When locked, the brake supplies 2.45 Nm of static holding torque to help prevent drift on vertical or suspended loads. The motor uses frame size 041, which matches the mounting dimensions associated with this housing format.

The motor has length code B, which indicates the housing depth used for this version and affects inertia and thermal mass without changing the basic frame diameter. Its 0300 winding is matched to low-voltage IndraDrive controllers that use high current for dynamic response. As a synchronous motor, it generates torque through permanent-magnet interaction and supports smooth motion over the usable speed range. A built-in holding brake helps keep the axis in position when power is removed. The compact form also suits installations where available mounting space is limited.
