Mitsubishi Electric HS-MF23EX-S2 AC Servo Motor

The Mitsubishi Electric HS-MF23EX-S2 AC Servo Motor is an ultra-low inertia servo from the HS-MF Series, engineered for ultra-high-speed positioning and precise motion control in CNC and industrial automation systems. It carries Manufacturer Part Number HS-MF23EX-S2 and delivers about 0.2 kW of rated output with a rated speed of roughly 3000 RPM, paired with an encoder resolution of about 8000 pulses per revolution and capacitor regeneration (no external resistor). The compact molded construction supports high heat dissipation, and the unit is designed for CNC machine tool peripheral axes with compatibility to Mitsubishi MDS-B-SVJ2 and MR-J2-CT systems; as of now it is obsolete, with common replacements including HS-MF23EXV-S2, HC-MFS23, and HF-KP23.
