Product Description:

The MSM041B-0300-NN-M5-ML0 is a compact servo unit manufactured by Bosch Rexroth Indramat and supplied as part of the MSM IndraDyn S Synchronous Motors series. Designed for direct connection to IndraDrive amplifiers, this motor serves as the rotary actuator in small pick-and-place modules, indexing tables, and light conveyor axes within automated assembly lines. Its role is to convert commanded current from the drive into precise mechanical rotation so position, speed, and torque can be regulated in closed-loop motion sequences.

Under continuous stall conditions, the rotor can develop 2.40 Nm, so the axis can hold modest loads without additional gearing. Thermal energy is expelled by natural convection, allowing installation without external fans. The motor is supplied without a holding brake, so vertical axes require a mechanical clamp or drive-applied holding torque. A length code of B pairs a medium stack height with the narrow frame, while frame designation 041 keeps the housing diameter suitable for 40 mm mounting patterns. The winding code 0300 matches the motor to low-voltage, high-current drive stages used in compact automation cells.

The length and frame codes give the motor low rotor inertia, enabling swift acceleration and deceleration in short-stroke cycles. The winding selection balances voltage utilization with thermal behavior, which supports continuous duty even when airflow inside the cabinet is restricted. As a closed-loop Synchronous Motor, the unit maintains a fixed angle between the stator field and rotor magnets, which helps minimize speed ripple during coordinated multi-axis moves. When integrated with high-resolution feedback, its smooth torque profile improves contour accuracy, shortens settling times, and reduces mechanical wear across miniature assembly platforms and laboratory automation equipment.
