Product Description:

The MSM020B-0300-NN-C0-CC1 is a compact servo motor built by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. Designed for use with IndraDrive amplifiers, the unit converts electrical energy into precisely metered torque. This allows small conveyors, feed rollers, and gantry axes to follow tightly controlled motion profiles in automated assembly, packaging, and electronics production cells.

The friction brake on this motor employs an electrical release system, so its spring force secures the shaft whenever supply voltage is absent and disengages only when a dedicated 24 V line is energized. Thermal management relies on natural convection; no fan or liquid circuit is provided, making surface area and ambient airflow critical to continuous-duty ratings. All power, sensor, and brake leads exit the housing through a molded cable tail that maintains IP-grade sealing while allowing plug termination elsewhere in the cabinet. For commutation, the rotor is monitored by an incremental encoder that delivers phase-aligned square-wave signals to the drive controller. During idle or fault states, the brake sustains up to 0.29 Nm to help prevent coasting or misalignment.

A dedicated holding brake remains engaged whenever the safety circuit removes drive power, which helps maintain position on vertical axes. Physically, the motor belongs to frame size 020, while its axial stack is identified by length code B; these dimensional markers establish the flange geometry and overall body depth needed for mechanical layout. Electromagnetic behavior is tied to winding code 0300, which indicates the turns count and resistance used for rated torque at lower bus voltages in compact machinery. Classified for synchronous servo duty, the motor delivers consistent torque up to rated speed with minimal ripple, supporting precise indexing cycles and tight motion synchronization across multi-axis automation platforms.
