ECMA-C20807RS 750W AC Servo Motor 3000rpm 17-Bit | Delta

The Original New Delta ECMA-C20807RS is a 750 W low-inertia AC servo motor from the ECMA series, designed for high-precision motion control in general-purpose machine automation. Rated 750 W (1 HP) at 220 V AC with 3000 rpm rated speed and 2.39 N·m rated torque, this low-inertia motor delivers fast dynamic response for loads with minimal inertia. 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 17-bit incremental encoder (160,000 pulses/revolution), keyway shaft with tap, and an 80 mm frame size, the ECMA-C20807RS is suitable for packaging machinery, textile equipment, material handling systems, and small CNC applications. This model is compatible with Delta ASDA-B2 and ASDA-A2 series servo drives.
