Product Description:

The MSM019B-0300-NN-M5-MH0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat within the MSM IndraDyn S Synchronous Motors series. It is intended for direct coupling to lightweight mechanical axes, enabling precise torque and speed control under closed-loop feedback in packaging, assembly, and small handling equipment. The unit serves as the electromechanical interface between the inverter and the load, converting electrical power into rotational motion for automated positioning tasks. Its compact format also suits installations where moving mass and available mounting space must be kept low.

At standstill, the rotor can supply a continuous torque of 0.32 Nm, which is the maximum static load the motor can support without losing position. Heat produced by copper losses is dissipated through natural convection, so installation must maintain free air passages around the housing. The stator uses the compact 019 frame size, which suits tight mounting spaces on small machine axes. The motor has a length B housing that balances torque density with a short overall package length. The output shaft is a plain shaft, which allows direct clamping or keyless hub connections. The motor is supplied without a holding brake, so vertical axes or gravity-loaded mechanisms require external locking or drive-applied holding current when power is removed.

Dynamic electrical behavior follows winding code 0300, which matches the voltage constant and rated current range used with 300 V class IndraDrive amplifiers. There is no shaft seal, so the motor is best used in dry, nonpressurized enclosures to help prevent bearing contamination. The motor uses synchronous vector control, enabling repeatable speed and position regulation across its load range without encoder slip. This control method also supports smooth low-speed motion and stable response during frequent start-stop cycles, while the lack of additional sealing components helps keep friction and inertia low.
