MITSUBISHI HG-KR43B Servomotor

In the world of industrial automation, where precision and speed are paramount, the choice of a servomotor can significantly impact the performance of your machinery. The MITSUBISHI HG-KR43B, a low-inertia, compact servomotor from the renowned MELSERVO-J4 series, stands out as a powerful solution for applications demanding high-frequency operation and exceptional responsiveness. 

Key Technical Parameters and Data

Understanding the specifications is crucial to appreciating the capabilities of the HG-KR43B. This motor is designed for high-performance tasks with the following key parameters:

Power and Torque: The HG-KR43B delivers a rated output of 400W . It provides a rated torque of 1.3 N·m, with a robust maximum torque of 4.5 N·m , which is about 350% of its rated torque, ensuring strong acceleration and the ability to handle sudden load changes effectively .

Speed and Performance: Its rated speed is 3,000 rpm, and it can achieve a maximum speed of 6,000 rpm . This wide speed range allows for both precise control at lower speeds and high-velocity operation. Furthermore, it can momentarily tolerate speeds up to 6,900 rpm .

Precision Encoding: At the heart of its precision is a high-resolution 22-bit absolute/incremental encoder . This provides an astounding 4,194,304 pulses per revolution , enabling incredibly accurate positioning and smooth low-speed operation.

Durability and Design: The motor is built with a protection class of IP65 , making it resistant to dust and water jets, which is essential for operation in harsh industrial environments. It features a square 60mm flange  and a straight shaft (with an optional keyway variant available, the HG-KR43BK) . Its low inertia design, with a rotor moment of inertia as low as 0.371 x 10⁻⁴ kg·m² , is key to its rapid response.

Electrical and Braking Specifications: It operates on a three-phase 200V AC supply . For safety and holding applications, an optional electromagnetic brake is available, which has a static friction torque of 1.3 N·m and operates on 24V DC .

Defining Features and Strengths

The parameters above translate into a set of powerful features that define the HG-KR43B's value proposition:

Exceptional Responsiveness: The combination of low inertia and high torque enables the motor to achieve extremely high acceleration and deceleration rates . This makes it perfectly suited for applications with rapid start-stop cycles, significantly reducing cycle times and boosting productivity.

Superior Precision and Stability: The ultra-high-resolution 22-bit encoder ensures that every movement is executed with extreme accuracy. This is critical for applications like assembly and printing, where positional error is not an option. The high resolution also contributes to exceptional stability at very low speeds .

Robust and Reliable Construction: With an IP65 protection rating , the motor is shielded from contaminants commonly found in industrial settings, such as oil mist and dust. This built-in durability ensures long-term reliability and reduces downtime.

Seamless System Integration: As part of the MELSERVO-J4 series , the HG-KR43B is designed to work flawlessly with Mitsubishi's advanced servo amplifiers, like the MR-J4 series . This system integration provides access to advanced tuning, vibration suppression control, and comprehensive diagnostics, simplifying setup and optimization .

Ideal Application Scenarios

The technical prowess of the HG-KR43B makes it an ideal choice for a wide range of high-speed automation equipment:

Packaging and Handling Machinery: Its high-speed and high-acceleration capabilities are perfect for pick-and-place robots, sorting systems, and conveyor belt drives that require fast and precise movement .

Printing and Paper Processing Equipment: The motor's ability to maintain precise positioning at high speeds is crucial for achieving accurate registration and high-quality output in printing and converting machines .

Semiconductor and Electronic Assembly: In the production of electronics and semiconductors, the need for pinpoint accuracy is non-negotiable. The HG-KR43B's high-resolution encoder ensures the precision required for inserting components and handling wafers .

Advanced Industrial Machinery: From the precise X-Y tables in cutting machines to the intricate movements of sewing and embroidery machines, this servomotor provides the motion control backbone for enhancing performance and quality .
