The DELTA ECMA-F11845RS Servo Motor (4.5KW) is a premium-grade, high-inertia motor built for precision motion control in industrial automation. This 4.5 kW unit delivers a continuous torque of 28.65 Nm at a rated speed of 1500 rpm, making it a perfect match for applications requiring high torque at lower speeds, such as packaging, printing, robotics, and CNC machinery. The motor features a 20-bit absolute encoder that provides exceptional position feedback accuracy and repeatability, ensuring minimal error in closed-loop systems. Its big inertia design enhances stability during rapid acceleration and deceleration, reducing mechanical resonance. The ECMA-F11845RS includes an oil seal and a key-way shaft with screw holes for secure mounting and protection against contaminants, extending operational life. When paired with the ASD-A2-4523-B servo drive (3-phase, 220V AC), this motor forms a high-performance servo system capable of advanced motion profiles. Every unit is 100% original and new, sourced directly from authorized channels, and shipped globally with full warranty support.
