Rated output is 0.2 kW at 3000 r/min, with a rated current of 1.5 A and maximum torque of 2.2 N·m. The HG-KR23J motor includes an oil seal (J designation), making it suitable for applications where exposure to oil mist or splash is expected — common on machine-tool spindles, transfer lines, or packaging equipment where lubricant contamination is a concern. Control is sine-wave PWM current control, which gives smooth torque at low speeds and reduces audible noise compared to trapezoidal drives. The amplifier's general-purpose interface (A type) accepts standard pulse-train or analog speed/torque commands from a motion controller or PLC. The 0.2 kW / 3000 r/min rating sizes this for small-axis motion — think indexing tables, pick-and-place Z-axes, conveyor diverters, or label applicators. The 1.5 A rated current and 2.2 N·m peak torque tell you the amplifier's drive stage is matched to the motor's winding; no oversizing or derating guesswork.","metaTitle":"Mitsubishi MR-J4-20A+HG-KR23J Servo Amplifier & Motor, 0.2 k","metaDescription":"MR-J4-20A+HG-KR23J servo amplifier and HG-KR23J motor combo. 0.2 kW rated output, 3000 r/min, 1.5 A rated current, 2.2 N·m max torque.
