Product Description:

The MSM020B-0300-NN-M0-CC1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSM IndraDyn S Synchronous Motors series. This compact rotary unit converts electrical energy into controlled mechanical rotation for positioning tasks and speed regulation in industrial automation cells such as pick-and-place gantries, packaging axes, and light assembly stations. By pairing with IndraDrive controllers, it forms a closed-loop drive capable of executing repeatable motion profiles.

Thermal management relies on natural convection, so the housing must remain exposed to ambient air without forced airflow. The built-in brake is an electrically released type; it stays engaged when power is removed and unlocks only when current is supplied, simplifying vertical-axis safety circuits. Power and feedback conductors exit as a cable tail, allowing quick routing through drag chains instead of fixed connectors. Rotor position is recorded by a multiturn absolute encoder, enabling the drive to recover its position after a power outage without homing. A dedicated holding brake is included to prevent shaft movement during maintenance or emergency stops and to secure the load when the drive is disabled.

Static retention capability reaches 0.29 Nm, which is sufficient for the low-inertia mechanisms typically paired with this motor. The mechanical envelope follows IndraDyn coding; it belongs to size 020, giving a 20 mm frame diameter, and corresponds to length B, which sets the stack height and influences continuous torque capacity. Electrical behavior is set by winding code 0300, so the connected drive must supply the matching voltage and current profile to achieve nominal speed without saturation. These dimensional and winding parameters affect gear ratio selection, drive sizing, and mounting clearances in compact servo axes.
