Delta Electronics ECMA-J11020RS AC Servo Motor

Delta Electronics ECMA-J11020RS AC servo motor delivers high-speed, high-torque precision control for industrial automation systems. The 2.0 kW motor operates at 400 VAC with a rated speed of 3000 RPM and a rated torque of 6.37 Nm, capable of reaching up to 5000 RPM with a peak torque of 19.11 Nm for demanding motion profiles. Part of the ECMA-A2 Series, it uses a 20-bit incremental encoder in a 100 mm frame, with IP65 protection, a keyway shaft with oil seal, and a standard configuration without an integral brake. Weighing approximately 6–6.2 kg, this servo motor is designed for Delta ASDA-A2 servo drives to ensure straightforward integration in Delta-based automation systems. Typical applications include CNC machining centers, robotic systems, packaging lines, rotary cutting, and printing machines where fast, precise motion is required to maintain accuracy, enable smooth acceleration, and provide reliable torque during positioning, synchronization, and high-speed cycles. Common replacements in Delta’s servo motor lineup include ECMA-J11020SS, ECMA-C11020RS, and ECMA-J11330RS motors.
