ECMA-E21310RS 1kW AC Servo Motor 2000rpm 17-Bit Encoder | Delta

The Original New Delta ECMA-E21310RS is a 1 kW medium-inertia AC servo motor from the ECMA E2 series, designed for precision motion control in industrial automation applications. Rated 1 kW (1.3 HP) at 220 V AC with 2000 rpm rated speed and 4.77 N·m rated torque, this motor delivers stable, reliable 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 17-bit incremental encoder (160,000 pulses/revolution), keyway shaft with tap, and a 130 mm frame size, the ECMA-E21310RS is suitable for CNC machine tools, industrial robots, packaging machinery, and material handling systems. This model is compatible with Delta ASDA-B2 and ASDA-A2 series servo drives.
