Product Description:

The MSM019B-0300-NN-M0-CH1 is a synchronous motor produced by Bosch Rexroth Indramat within the MSM IndraDyn S Synchronous Motors series. Designed as a compact servo element, it converts controlled electrical power into rotary motion for positioning tables, pick-and-place heads, and similar automation axes. The combination of permanent-magnet excitation and integrated feedback allows closed-loop velocity and position control, helping machinery maintain repeatable motion without an external encoder. Its compact format makes it suitable for small axes where limited installation space and responsive movement are both important.

At standstill, the rotor can deliver 0.32 Nm of continuous torque, which is suitable for light manipulation tasks without overheating. Heat is removed by natural convection, so the motor does not require forced-air devices. Rotor position is reported by a multi-turn absolute encoder, allowing the controller to retain position information after power loss. Power and feedback conductors exit through a cable tail, which supports direct routing into compact machine assemblies. Motion is controlled by a spring-loaded brake that is electrically released, so the brake engages whenever supply power is removed.

For stopping and load holding, the integrated brake provides 0.29 Nm of holding torque, which helps keep light vertical axes in place when the motor is disabled. The stator uses winding code 0300, which matches the electrical characteristics expected by standard IndraDrive controllers. Mechanical coupling is made through a plain shaft, allowing use with clamping hubs or rigid couplings that do not require a keyway. Frame code 019 sets the flange dimensions for miniature stages, while motor length B adds axial space for the winding section without changing the mounting pattern. The motor has no shaft seal, so it is better suited to dry installations that are not exposed to direct fluid spray.
