Product Overview: Mitsubishi HC-KFS43 Servo Motor
The Mitsubishi HC-KFS43 is a high-performance AC servo motor belonging to the acclaimed MELSERVO-J2-Super series. Engineered with a low-inertia design, this motor is specifically optimized for applications requiring rapid acceleration and deceleration, such as pick-and-place robotics, electronic component inserters, and high-speed packaging machinery. Its compact frame and high power density make it a global standard for precision motion control in small-to-medium capacity automation cells.
Technical Excellence and Encoder Precision
The HC-KFS43 provides a rated output of 400 Watts and operates at a rated speed of 3000 r/min. It features a high-resolution incremental encoder that ensures sub-millimetric positioning accuracy and smooth rotation even at low speeds. The low-inertia rotor design allows for extremely dynamic responses to control commands, reducing overall cycle times in high-throughput manufacturing environments. Built with high-grade permanent magnets and advanced thermal management, it maintains consistent performance under continuous industrial operation.
