Product Description:
The MSM019A-0300-NN-M0-CH1 is a synchronous motor produced by Bosch Rexroth Indramat as part of the MSM IndraDyn S Synchronous Motors series. This compact rotary unit converts electrical energy into controlled shaft motion for smaller axes in material-handling cells, laboratory automation, and electronics assembly. It is intended for closed-loop servo axes that need repeatable low-power motion in compact machinery. Its compact format makes it suitable for installations where several actuators must fit close together without sacrificing controlled motion. An integrated brake secures the load whenever supply power is removed, making the motor suitable for vertical axes and other positions that require controlled stopping.
At standstill, the rotor can deliver a continuous torque of 0.16 Nm, giving the axis enough holding capacity for positioning tables and grippers without exceeding thermal limits. The brake is electrically released, so it disengages only when current is applied and automatically engages after power loss. This arrangement supports predictable holding behavior during shutdown events and helps prevent uncommanded drift at rest. Heat is removed by natural convection, so no forced-air or liquid-cooling circuit is required and clearance around the housing remains important for airflow. A multi-turn absolute encoder provides unique position data across several mechanical revolutions, which supports immediate position availability when the system starts. All power, feedback, and brake conductors exit through a single cable tail, which helps when the motor must be routed through narrow cable paths.
The braking element develops 0.29 Nm of static torque. Motion is transferred through a plain shaft, so couplings must rely on clamping or hub screws rather than keyways. With a frame size of 019 and compact length code A, the motor occupies minimal space beside neighboring actuators. The motor uses winding set 0300, which gives the drive controller a fixed resistance and inductance profile for parameter selection. There is no shaft seal, so the installation area must remain protected from fluid ingress and heavy contamination. Because the shaft is unsealed, the motor is better suited to clean, dry machine sections than to locations exposed to washdown or coolant.
