Product Description:

The MMD012A-030-EG0-CN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MMD Synchronous Motors series. It is intended for compact positioning axes and light pick-and-place units where precise torque delivery and feedback are required for industrial automation. The motor includes an incremental encoder for closed-loop position control, and it uses a plain shaft with a shaft seal to transmit motion while helping keep contaminants away from the internal bearings. This combination suits compact axes that need accurate feedback and a sealed mechanical interface.

This model delivers a rated output of 100 W at a nominal speed of 3000 rpm, providing a predictable operating point for continuous duty. A continuous standstill torque of 0.32 Nm allows the axis to hold load at zero speed without overheating under normal conditions. The housing has an IP65 rating, so dust and low-pressure water jets are kept away from internal components when the shaft seal is intact. Feedback resolution reaches 2,500 increments, which supports fine positioning through the incremental encoder. Mechanical mounting uses a 45 mm square flange and a 30 mm centering recess, and winding code 030 identifies the coil set used with the matching servo drive.

For short bursts, the rotor can accelerate to 5000 rpm and produce up to 0.95 Nm of torque to overcome temporary load peaks. A rotor inertia of 6.3 × 10⁻⁶ kg·m² supports rapid speed changes, and the motor mass of 0.53 kg helps keep moving assemblies light on compact gantries. The shaft diameter is 8 mm, and the plain design means no keyway is provided. There is no holding brake, so vertical loads require external retention. Operation is permitted up to 85% relative humidity and 1000 m installation altitude, and the A length code indicates the shortest housing option for tight spaces.
