Product Analysis: Mitsubishi HC-KFS73 Servo Motor
The Mitsubishi HC-KFS73 is a precision AC servo motor from the world-renowned MELSERVO-J2-Super series. With a rated output of 750 Watts (0.75kW), this motor is specifically designed with a low-inertia rotor. This configuration is optimized for high-dynamic applications that require rapid acceleration, deceleration, and frequent start-stop cycles, such as pick-and-place robotics, electronic component inserters, and high-speed packaging equipment.
High-Dynamic Performance and Encoder Resolution
The HC-KFS73 operates at a rated speed of 3000 RPM, providing a stable torque of 2.4 N·m. It is equipped with a high-resolution 17-bit incremental encoder (131,072 pulses per revolution), which provides the servo amplifier with sub-millimetric position feedback. This level of precision ensures smooth rotation at low speeds and superior path-following accuracy during complex multi-axis motion. The motor’s electrical design is optimized for use with the MR-J2S-70A or MR-J2S-70B servo amplifiers.

System Integration and Durability
Built for the rigors of the modern factory floor, the HC-KFS73 features high-grade permanent magnets and high-durability bearings. Its compact frame allows for installation in tight machine spaces, while the IP55 rating ensures that the internal windings are protected from industrial contaminants. The motor’s low inertia reduces the load on the drive’s regenerative brake during deceleration, which increases overall system efficiency and longevity.

Technical Note
The HC-KFS73 is a non-brake model; if your application requires a vertical axis or safety hold during power loss, the HC-KFS73B (with electromagnetic brake) should be utilized. Always use original Mitsubishi encoder and power cables to maintain signal integrity and IP rating.
