ECM-B3M-C20807RS1 750W AC Servo Motor 3000rpm 24-Bit Encoder | Delta

The Original New Delta ECM-B3M-C20807RS1 is a 750 W medium-inertia AC servo motor from the ECM-B3M series, designed for high-precision motion control in industrial automation applications. Rated 750 W (1 HP) at 220 V AC with 3000 rpm rated speed and 2.4 N·m rated torque, this medium-inertia motor delivers stable performance for loads with significant mass fluctuations. The integrated oil seal protects internal windings and encoder from lubricant and cutting fluid ingress, extending operational life in demanding machining environments. Equipped with a 24-bit incremental optical encoder, keyway shaft with tap, and an 80 mm frame size, the ECM-B3M-C20807RS1 is suitable for CNC machine tools, industrial robots, packaging machinery, and material handling systems. This model is compatible with Delta ASDA-B3 series servo drives.
