HG-KR23 200W Low-Inertia AC Servo Motor 22-Bit Encoder | Mitsubishi

The Original New Mitsubishi HG-KR23 is a 200 W (0.2 kW) low‑inertia AC brushless rotary servo motor from the MELSERVO J4 series, designed for high‑frequency positioning and rapid acceleration/deceleration applications in industrial automation systems. Featuring a built‑in 22‑bit absolute feedback encoder (4,194,304 pulses/revolution) and a straight shaft design, it delivers high‑precision position feedback and reliable performance for applications requiring fast response and precise positioning. The motor is equipped with a 60 mm × 60 mm flange mounting interface and IP65 protection, making it suitable for semiconductor manufacturing equipment, pick‑and‑place systems, and general factory automation.
