Product Description:

The MMD082A-030-EG0-CN is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MMD Synchronous Motors series. This product operates as the rotary actuator in servo axes that demand accurate speed and position control on carton erectors, pick-and-place gantries, and small indexing tables. Coupled with a matched drive controller, its permanent-magnet rotor and incremental feedback enable closed-loop torque and velocity regulation, giving machine builders an actuator that fits restricted mounting spaces while sustaining continuous industrial duty cycles.

It delivers a continuous standstill torque of 2.4 Nm, allowing the axis to resist process loads without motion during clamp or dwell phases. With a rated mechanical output of 750 W, the unit covers moderate-power conveyor, feeder, or tooling drives. The rotor maintains a nominal speed of 3000 min⁻¹, matching common 50/60 Hz inverter settings, while the winding permits a maximum theoretical speed of 4500 min⁻¹ for brief rapid-positioning bursts. A housing classified at IP65 shields the stator windings and encoder from dust and water jets encountered in wash-down or machining cells.

Mechanical characteristics complement these electrical limits. Peak torque rises to 6.9 Nm to handle acceleration spikes, and a rotor inertia of 1.33 × 10⁻⁴ kg·m² supports quick direction changes with minimal overshoot. Overall motor mass is only 3.1 kg, reducing moving weight on linear carriages. Installation centers on a pilot diameter of 70 mm; the plain 19 mm shaft is protected by an integral sealing ring to prevent lubricant loss. Additional attributes include a 90 mm square flange, 80 mm mounting face width, incremental encoder resolution of 2,500 increments, altitude capability to 1000 m, and the absence of a holding brake for systems that rely on drive torque for static positioning.
