Product Description:

The MSM020B-0300-NN-M0-CC0 is an electric motor produced by Bosch Rexroth Indramat as part of the MSM IndraDyn S synchronous motors series. It converts electrical power into controlled rotary motion for industrial automation equipment, where compact dimensions and consistent torque help synchronize machine operations. Its size makes it suitable for small axes used in feeders, transfer units, and other space-limited assemblies. Stable rotary output also supports repeatable motion in applications that depend on precise starts, stops, and speed changes.

This model relies on natural convection, so heat is removed through its housing surfaces without fans or external liquid circuits. Because no forced airflow is present, installation clearances around the housing must be maintained to let heat rise freely. Power and feedback conductors emerge as a factory-installed cable tail, reducing connector count and simplifying routing inside a cabinet. For position feedback, a multi-turn absolute encoder is fitted, allowing the controller to recover shaft position after a power loss. The unit is supplied without a holding brake, so mechanical retention must be provided by the drive or by external clamping when static load security is necessary. The motor uses winding code 0300, which corresponds to coil resistance and inductance values matched to drives with the required current and voltage range.

The motor has length code B, which indicates the housing depth, and frame size 020, which provides a standardized flange outline for mounting on small transfer stations. The Synchronous Motor design means the rotor field locks in step with the stator excitation, eliminating slip and supporting accurate speed tracking across the load range. This combination helps the motor operate predictably in indexing, positioning, and transfer tasks. Its compact housing also suits tightly packed axes where wiring space and cooling clearance are limited.
