Specification

The MITSUBISHI MELSERVO-J3 SERVOMOTOR WITH BRAKE 750W HF-KP73B is a top-tier low-inertia, small-capacity servo motor engineered for applications requiring rapid acceleration, high precision, and fail-safe braking. Part of the acclaimed HF-KP series, this 750-watt model delivers exceptional dynamic response with a maximum speed of 6000 r/min and a permissible instantaneous speed of 6900 r/min. Its built-in electromagnetic brake ensures reliable holding torque, making it a safe choice for vertical axis loads or emergency stops. The 18-bit encoder provides high-resolution feedback, enabling tight position control in packaging, robotics, and CNC machinery. With an IP65 enclosure, the HF-KP73B withstands harsh industrial environments, while its compatibility with MR-J3-70 series amplifiers simplifies system integration. Below are the full technical specifications for this model and related HF-KP series motors.
