Product Description:

The MMD042A-030-EGO-CN is built by Bosch Rexroth Indramat and belongs to the MMD Synchronous Motors series. Its type code identifies it as a synchronous motor for compact automation modules. Because it uses synchronous operation, the drive can regulate torque and speed with predictable response during short indexing moves and repeated start-stop cycles. Winding code 030 and the short A length keep the stator stack small, making it a lightweight rotary actuator for pick-and-place stages, feeders, transfer units, or auxiliary axes where installation space is limited and precise repeatability is required.

At standstill, the motor supplies 1.3 Nm of continuous torque without excess heating. During rated operation, it runs at 3000 rpm while delivering up to 400 W, a combination suitable for moderate-inertia mechanisms and steady cyclic motion. The housing has an IP65 protection rating, so dust and low-pressure water do not threaten the internal windings. Position feedback comes from an incremental encoder that produces 2,500 increments per revolution, helping the connected drive maintain smooth speed correction and accurate response during direction changes. Rotor inertia is 0.37 × 10⁻⁴ kg·m², which supports quick reversals, and power is routed through a plug-in connector for straightforward wiring in tight enclosures.

For transient events, the rotor can reach 5000 rpm and generate up to 3.36 Nm, supplying extra headroom for rapid indexing or short overloads. A plain 14 mm shaft with a sealing ring exits a 70 mm square flange, and mounting accuracy is helped by a 50 mm centering diameter. The shaft arrangement is suited to direct couplings, pulleys, or compact gearheads where a sealed output is preferred. The low mass of 1.6 kg minimizes moving load on linear systems, and the motor is cleared for continuous duty up to 1000 m elevation without derating.
