Product Description:
The MMD022A-030-EG1-CN is a compact rotary actuator manufactured by Bosch Rexroth Indramat for the MMD Synchronous Motors series. Intended for positioning tables, small gantries, and feed drives, it converts electrical energy into precisely regulated motion for light-duty automation axes. An incremental encoder with 2,500 increments is integrated for real-time feedback, allowing the drive controller to correct position deviations within each cycle. Powered by a single-phase supply, the unit fits installations that demand accurate speed tracking without occupying much cabinet or machine space.
Its winding code 030 corresponds to conductor dimensions and inductance selected for a rated output of 200 W. At a nominal speed of 3000 rpm, the motor delivers 0.64 Nm of continuous torque, which is used when sizing the drive electronics for steady operation. Operation from a 230 V bus allows the controller to reach shaft speeds up to 5000 rpm during transient moves. At that peak speed, the motor can reach 1.91 Nm of maximum torque to help overcome inertial loads during rapid acceleration.
The integrated holding brake is electrically released and operates from a 24 V line that draws 0.4 A. Once energized, it can restrain the shaft with 1.3 Nm of static torque, helping hold vertical axes when the drive is inactive. With a rotor inertia of 0.00002 kg·m², the motor responds quickly to speed commands while reducing micro-vibrations in lightweight mechanisms. The housing has an IP65 rating and a shaft sealing ring for use in dusty or washdown areas where relative humidity stays below 85%. Mounting uses a centering diameter of 50 mm, a 70 mm square flange, and an 11 mm plain shaft with the same seal. The motor has length code A and a mass of 1.4 kg, which helps reduce payload on moving machine members.
