ECMA-L11830RS 3kW AC Servo Motor 1500rpm 20-Bit Encoder | Delta

The Original New Delta ECMA-L11830RS is a 3 kW medium-high inertia AC servo motor from the ECMA-L series, engineered for precise motion control in demanding industrial automation applications. Rated 3 kW (4 HP) at 400 V AC with 1500 rpm rated speed and 19.1 N·m rated torque, this medium-high inertia 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 20-bit incremental encoder (1,280,000 pulses/revolution), keyway shaft with tap, and a 180 mm frame size, the ECMA-L11830RS is suitable for CNC machine tools, industrial robots, injection molding equipment, and heavy-duty automation systems. This model is compatible with Delta ASDA-A2 series servo drives.
