The MITSUBISHI MELSERVO-JE SERVOMOTOR WITH BREAK 700W HG-KN73BJ-S100 is a robust and reliable AC servo motor designed for demanding motion control applications. This model features a built-in electromagnetic brake that ensures secure holding torque during power-off conditions, making it ideal for vertical axes, robotic arms, and other safety-critical systems. With a rated output of 700W and a high-resolution 22-bit incremental encoder, it delivers precise speed, position, and torque control across a wide operating range. The motor is factory-tested and comes with a standard IP65 protection rating (excluding shaft and connector), ensuring durability in dusty or wet environments. It is fully compatible with MITSUBISHI MELSERVO-JE series amplifiers, enabling seamless integration and advanced performance tuning.
