HF-KP73B MITSUBISHI Industrial Servo Drives 200-230v 20.00 Lbs 1.5/0.6A
HF-KP73B Description
The Mitsubishi HF-KP73B is a high-performance, low-inertia AC servo motor designed for use with the MELSERVO‑J3 series amplifiers. With a rated power of 750W, it delivers fast response, high precision, and stable torque output for positioning, speed control, and continuous duty applications in compact automation machinery. This model features a built-in 18-bit absolute encoder and a smooth, keyway-free shaft with a tapered rear section for high‑speed balance and low vibration. It is widely used in high‑speed assembly, conveying, machining, and robotics where accuracy and dynamic performance are critical.
HF-KP73B Key Features
- Low‑inertia rotor design for extremely fast acceleration and deceleration
- 18‑bit absolute encoder (262,144 pulses/rev) for ultra‑high positioning accuracy
- Smooth, keyway‑less shaft for high‑speed operation and low vibration
- High torque-to-inertia ratio ideal for high‑frequency start‑stop motion
- Compact, lightweight construction for space‑constrained equipment
- IP65 front protection (excluding shaft end) against dust and water splashes
- Built-in thermal protection for safe continuous operation
- Excellent low‑speed smoothness and minimal cogging
- Fully compatible with MR-J3 series servo amplifiers
