Product Description:

The MMD042A-030-EG1-CN is a synchronous motor produced by Bosch Rexroth Indramat within the MMD Synchronous Motors series. It supplies rotary motion for automated equipment where a drive controller supervises speed and position through the built-in incremental encoder, allowing accurate response during indexing and repeated start-stop cycles in automated handling equipment. A plain shaft, an integrated holding brake, and sealed construction allow direct coupling to gearboxes or timing pulleys while protecting the bearing set from contamination. Because the unit weighs only 2.0 kg, it fits lightweight servo axes on pick-and-place gantries, electronic assembly lines, and other compact motion systems.

Beneath the square mounting flange, the stator delivers continuous mechanical power of 400 W and produces standstill torque of 1.3 Nm when the shaft is locked. Winding code 030 allows peak operation up to 5000 rpm, so short-stroke moves can finish quickly during repetitive motion in short transfer axes. The holding brake operates on 24 V / 0.4 A and releases electrically, letting the axis move only after a controller command. A flange width of 70 mm and a 50 mm centering pilot help keep the motor concentric with the driven load, while the plug-in connector simplifies cable attachment.

During continuous duty, the rotor runs at a nominal speed of 3000 rpm, which supports steady throughput in normal operation. The housing has an IP65 rating, so airborne dust or coolant spray is kept away from the internal windings. Low rotational inertia of 0.4 × 10⁻⁴ kg·m² helps the drive respond quickly to changing commands. Position feedback is generated by an encoder with 2,500 increments per revolution, supporting fine velocity control at low speed and accurate position correction during short positioning moves. With a shaft seal, a 14 mm journal, and operation permitted up to 1000 m elevation, the motor fits neatly into compact drive systems.
