Product Description:

The MSM030B-0300-NN-C0-CG1 is a compact motor from Bosch Rexroth Indramat that belongs to the MSM IndraDyn S Synchronous Motors series. It is intended for precise positioning and speed control in automated assembly stations, small handling modules, and packaging lines. By pairing permanent-magnet synchronous technology with integrated feedback, the unit converts drive current into controlled rotary motion for tightly regulated axes. Its compact format makes it suitable for installations where axis space is limited but accurate motion is still required.

Thermal management relies solely on natural convection, so no external blower or liquid loop is required. Ambient airflow removes the copper and iron losses generated during normal duty, which keeps the cooling concept simple and quiet. Power and feedback conductors exit through a factory-installed cable tail, simplifying routing in confined spaces and reducing connector bulk at the motor housing. Rotor position is reported by an incremental encoder, allowing the drive to close the speed and position loops with fine resolution but without absolute multi-turn data. Emergency and static holding force is supplied by the built-in brake, which has a torque capacity of 1.27 Nm. The brake uses an electrical release, so it disengages when energized and applies force when power is removed.

The frame diameter is 030, and the motor has a stack length of B. This combination gives the unit a short body that fits axes with restricted installation depth. The winding code is 0300, which is matched to operation with compatible IndraDrive compact inverters. A built-in holding brake helps keep vertical or indexing axes in place when the machine is de-energized. The passive cooling arrangement also supports use in compact assemblies where extra airflow hardware would take up additional space.
