Product Description:
The MSM019B-R300-NN-M5-MH1 is a compact synchronous motor from Bosch Rexroth Indramat in the MSM IndraDyn S Synchronous Motors series. It serves as a rotary actuator for light-duty axes where precise speed and position control are required in industrial automation cells, pick-and-place modules, and laboratory equipment. The motor can couple directly to small loads and return motion data to the drive for closed-loop control. This layout supports accurate starts, stops, and short indexing moves where low inertia helps the axis respond quickly to command changes. It is suited to compact assemblies where space is limited and the motor is mounted close to the driven mechanism.
At standstill, the unit can provide a continuous torque of 0.32 Nm, which is the load it can hold continuously at rated winding temperature without overheating. Heat is removed through natural convection, so the housing needs free air around it and does not rely on external forced cooling. Natural cooling also keeps the motor package simple because no separate fan or air duct is required. The brake is electrically released, so applying power unlocks the rotor for motion and removing power allows the brake to clamp. The motor has length code B and frame size 019, which help match the housing to the available mounting space and surrounding machine parts.
An integrated holding brake secures the shaft when the drive is disabled, and it provides 0.29 Nm of static torque to resist back-driving on vertical or indexing axes. Power is transmitted through a plain shaft, which works well with precision couplings and avoids the fit issues that can come with keyed connections in small drive trains. The stator winding uses code R300, so the matching drive can apply the proper electrical values for controlled operation. Because the motor is built without a shaft seal, it is better suited to clean, dry locations where coolant spray or washdown exposure is not expected. This makes placement and enclosure design important when the motor is installed near fluids or contaminated process areas.
