Product Description:

The MMD012A-030-EG0-KN is a brushless AC motor manufactured by Bosch Rexroth Indramat for the MMD Synchronous Motors series. Its 45 mm square mounting flange and plain 8 mm shaft let it fit into tightly packed mechanisms and couple directly to miniature gear stages. A plug connector mounted toward the A-side includes about 25 cm of cabling, which helps simplify routing in compact handling axes. In industrial automation, the motor converts electrical energy into controlled rotary motion for pick-and-place heads, indexing tables, and other small positioning units. This makes it suitable for light-duty axes where low moving mass and short cable runs are important.

During steady holding conditions, the motor sustains 0.32 Nm of continuous torque, helping resist positional drift under rated load. The nominal operating speed is 3000 rpm, and thermal losses at that speed correspond to a mechanical output of 100 W. The enclosure has an IP65 rating to resist dust and low-pressure water jets, while a centering pilot of 30 mm helps align the housing to the mating machine surface. This sealing allows direct machine mounting without additional covers around the motor body. The housing uses the A-length option in the series, which keeps the motor compact for small-axis layouts.

For brief acceleration periods, the motor can reach 5000 rpm, and its low rotor inertia supports quick speed changes with limited overshoot. The unit weighs 0.53 kg, which helps reduce moving mass on dynamic axes and supports use on small mechanical slides. Position feedback comes from an incremental encoder with 2,500 increments per revolution, allowing the drive to monitor shaft position and velocity during closed-loop operation. This feedback supports stable commutation and speed regulation during repeated indexing moves. The shaft uses an 8 mm shaft seal, and the motor is supplied without a holding brake, so any static load retention must come from the drive or external mechanics.
