Description
The MITSUBISHI MELSERVO HC series AC servo motors, models HC-KFS43B, HC-MFS43, HC-MFS43K, and HC-MFS43B, are high-performance, compact servo motors designed for precise motion control in industrial automation. These 0.4kW motors feature a 17-bit absolute encoder for high-resolution positioning, offering reliable speed and torque control. The HC-KFS43B and HC-MFS43B models are equipped with an electromagnetic brake for holding applications, while the “K” variant (HC-MFS43K) emphasizes high response. Designed for seamless integration with MITSUBISHI servo amplifiers (e.g., MR-J4 series), they are ideal for applications requiring high accuracy, quick response, and durability in demanding environments.
