The MITSUBISHI MELSERVO-JE SERVOMOTOR 400W HG-KN43J-S100 is a cornerstone of the MELSERVO-JE series, engineered to deliver superior torque density and precision in a compact form factor. This servo motor integrates a 17-bit encoder for high-resolution feedback, ensuring smooth operation in applications such as CNC machinery, robotics, and packaging equipment. With a rated speed of 3000 r/min and a maximum torque of 3.8 N·m, it excels in both high-speed and high-torque scenarios. The motor’s IP65 protection and oil seal make it suitable for environments with dust and moisture, while its vibration resistance (X: 49 m/s², Y: 49 m/s²) ensures stable performance under mechanical stress. Below is a detailed specification table for the HG-KN43J-S100 and its related models for reference.
