Product Overview
When precision motion control demands high accuracy and reliability, the Mitsubishi HG-KR43BJ delivers. This brushless servo motor, part of the HG Series, integrates a 22-bit absolute feedback encoder for exceptional position sensing. With an output rating of 0.4 kilowatts and a rated speed of 3,000 RPM, it handles small power capacity applications with ease. The built-in electromagnetic brake ensures secure stopping, adding a layer of safety during operation.
Technical Specifications Breakdown
The HG-KR43BJ features a 22-bit absolute feedback encoder that provides a resolution of 4,194,304 pulses per revolution. This high resolution enables fine control over movement and accurate positioning. The motor operates at a rated speed of 3,000 RPM, making it suitable for tasks requiring quick acceleration and deceleration. Its low inertia design contributes to responsive performance, while the natural cooling method maintains operational temperature without additional fans.
The motor includes a 4-pin rectangular connector for straightforward wiring. The IP65 degree of protection indicates strong resistance to dust and water ingress, enhancing durability in various environments. An oil seal is included to protect internal components from contaminants, promoting longevity.
Industry Applications
In packaging machinery, the HG-KR43BJ provides precise control for labeling and filling operations. The high-resolution encoder ensures accurate positioning, reducing waste and improving throughput. For robotic assembly systems, the low inertia and built-in brake enable quick, repeatable movements with secure holding. These features make the motor ideal for applications where space is limited and reliability is critical.
Installation & Setup Guidance
Mount the HG-KR43BJ securely using the provided mounting flange. Connect the 4-pin rectangular connector to the compatible drive unit, ensuring proper alignment and locking. Verify the supply voltage class matches the 200 Volts AC Class requirement. For the built-in electromagnetic brake, wire the brake control signal according to the drive manual. Test the brake function before full operation to confirm proper engagement.
Maintenance & Reliability
Routine inspection of the oil seal and connector integrity helps maintain the IP65 protection level. Check for any signs of moisture or dust ingress around the connector and shaft seal. The natural cooling method requires no additional maintenance, but ensure adequate airflow around the motor to prevent overheating. Periodically verify the brake operation to ensure it holds the load securely.
Selection Guide & Purchasing Advice
Before ordering, confirm that the HG-KR43BJ matches your system's voltage class and mechanical interface. Verify the maximum axial load of 98 Newtons and maximum radial load of 245 Newtons meet your application requirements.
