Mitsubishi Electric HG-KR23K AC Servo Motor

The Mitsubishi Electric HG-KR23K AC servo motor from the MELSERVO-J4 series delivers 0.2 kW of power with 0.64 Nm rated torque and a 22-bit absolute encoder (≈4,194,304 pulses/rev) for precise positioning in industrial automation. This 200 VAC class device supports a rated speed of 3000 RPM and a maximum speed of 6000 RPM, with a low inertia design (≈0.221 kg·cm²) and IP65 protection, a 60 mm flange mount, and a keyway shaft. It uses natural cooling and weighs about 0.9 kg. Operating temperature ranges from 0 °C to 40–55 °C. Common replacements include the HF-KP23K (previous generation) and HG-KR43K (higher power variant), making it a straightforward upgrade within Mitsubishi’s automation ecosystem for CNC machines, robotic arms, conveyors, and packaging lines that require repeatable, high-precision motion.
