HF-KP73J MITSUBISHI Industrial Servo Drives 200-230V 22kW 12 VDC At 150 MA
HF-KP73J Description
The Mitsubishi HF-KP73J is a high-performance, low-inertia AC brushless rotary servo motor belonging to the MELSERVO-J3 series. With a rated power of 750W (0.75kW), it is engineered for precise, high-speed positioning and rapid acceleration/deceleration in compact industrial automation systems. The motor features a built-in 18-bit absolute encoder, standard straight shaft, and IP65-rated enclosure, making it ideal for general-purpose machinery requiring accurate motion control. It is designed to pair with MR-J3 series amplifiers for seamless, high-response servo operation.
HF-KP73J Key Features
- Low Inertia Design: Optimized for ultra-fast response and high-speed positioning (max. 6000 rpm)
- High Precision Control: 18-bit absolute encoder (262,144 pulses/rev) for exceptional positioning accuracy
- Compact & High Output: 750W power with 2.4 Nm rated torque and 7.2 Nm maximum torque
- IP65 Protection: Fully enclosed, self-cooled construction for dust and water resistance (except shaft end)
