Product Description:

The MMD082A-030-EG1-CN is a synchronous motor manufactured by Bosch Rexroth Indramat as part of the MMD Synchronous Motors series. It serves as a compact servo element, translating drive-controller current into precise rotary motion for pick-and-place gantries, indexing tables, and light-duty packaging axes. The A-length body allows installation where depth is restricted while still supporting the cycle times and positioning accuracy commonly required in automated assembly cells. Its synchronous design also helps the drive maintain stable speed and position control during repeated starts, stops, and short indexing moves.

At rated load, the motor delivers 750 W of mechanical output power at a nominal speed of 3000 rpm. It provides a continuous standstill torque of 2.4 Nm for holding static loads without overheating, and it can reach a theoretical peak torque of 6.9 Nm during short acceleration periods. Winding type 030 and high-energy magnets allow shaft speeds up to 4500 rpm, giving additional operating range for fast cyclic motion. Mechanical interfacing is simplified by a plain 19 mm shaft with a 35 mm extension, a 70 mm centering pilot, a 90 mm square flange, and 6 mm mounting holes that accept standard fasteners. These mounting features support straightforward alignment with compact couplings, pulleys, and other driven machine elements.

The motor is equipped with a holding brake that provides 1.3 Nm of static torque and operates from a 24 V, 0.4 A supply for electrically released braking. Environmental protection is provided by an IP65 housing and a sealing ring on the shaft end, helping keep out dust and low-pressure water spray. The combined rotor and brake inertia is 1.41e-4 kg·m², and the total motor mass is 3.7 kg, which supports responsive motion without making the assembly overly heavy. Position feedback is supplied by an incremental encoder with a resolution of 2,500 increments per revolution, allowing standard servo drives to track shaft movement accurately. The brake supports load holding when power is removed, while the encoder supplies the position data needed for closed-loop operation.
