Product Description:

The MSM041B-0300-NN-M5-MH1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. It serves as a drive element in automated pick-and-place units, small conveyors, and indexing tables, where accurate rotary motion is required for coordinated multi-axis operation. Its housing fits space-restricted machine frames and other installations where mounting room is limited. It can be placed close to tooling or feed components without taking up much machine space. The compact footprint also helps when adjacent components, cable runs, and guarding leave little free space around the axis.

During constant stall operation, the motor can deliver 2.40 Nm of torque. This value is the constant stall load the motor can hold without exceeding thermal limits. Heat produced under this condition is removed by natural convection, so no forced-air or liquid cooling accessories are required. This cooling method keeps the package simple and avoids the added space of external cooling hardware. The motor uses an electrically released holding brake, which is engaged by spring force and opens when power is applied to the brake coil. Frame size 041 identifies the stator size, while winding code 0300 indicates the electrical values used by the matching drive.

The brake provides 2.45 Nm of static torque, allowing the shaft to remain locked when system power is removed. With motor length code B, the unit keeps a short overall package that eases mounting in shallow enclosures and compact transfer assemblies. The short body can be useful where the motor sits beside slides, sensors, or mechanical stops. The motor uses a plain shaft, which supports coupling to precision gearheads or belt pulleys without keyway machining. Because the shaft has no seal, external protection is needed when dust, coolant, or other contaminants are present near the drive end.
