ECMA-E21315RS 1.5kW AC Servo Motor 2000rpm 220V | Delta

The Original New Delta ECMA-E21315RS is a 1.5 kW AC synchronous servo motor from the ECMA series, designed for precision motion control in industrial automation applications. Rated 1.5 kW (2 HP) at 220 V AC with 2000 rpm rated speed and 7.16 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 17-bit incremental encoder, keyway shaft with tap, and 130 mm frame size, the ECMA-E21315RS is suitable for CNC machine tools, industrial robots, packaging machinery, and heavy-duty conveyor systems. This product is compatible with Delta ASDA-B2 series servo drives.
