Mitsubishi Industrial Servo Motor HC SERIES HC-MF23K-S22 200W
HC-MF23K-S22 Description
The HC-MF23K-S22 is a compact, ultra-low inertia brushless AC rotary servo motor from Mitsubishi Electric’s MELSERVO HC series, engineered for high-speed, high-precision motion control in small-capacity industrial automation systems. With a rated output of 0.2 kW (200W), it delivers rapid acceleration/deceleration and precise positioning, paired with a built-in 17-bit incremental encoder (131,072 pulses/rev) for accurate speed and position feedback. This 200V-class motor features a straight keyed shaft, IP55 environmental protection, natural air cooling, and a 60×60mm standard flange mount, making it ideal for high-frequency, high-dynamic applications requiring fast response and tight positioning accuracy. It is fully compatible with Mitsubishi MR-J2 series servo amplifiers, ensuring seamless integration into legacy and modern motion control architectures.
HC-MF23K-S22 Key Features
