Product Overview
When a production line demands precise torque control and rapid response, the Mitsubishi HG-MR23B brushless AC servo motor delivers. This HG Series motor provides a rated output of 0.2 kW and operates at a rated speed of 3000 r/min. Its ultra-low inertia enables quick acceleration and deceleration, making it ideal for dynamic positioning tasks. Maintenance engineers appreciate the integrated electromagnetic brake, which ensures safe stopping during power loss or emergency stops.
Technical Specifications Breakdown
- Rated Torque & Maximum Torque: The HG-MR23B offers a rated torque of 0.64 Nm and a maximum torque of 1.9 Nm. This allows the motor to handle both steady-state loads and short-duration peak demands without compromising stability.
- Current Ratings: With a rated current of 1.5 A and a maximum current of 5.3 A, the motor maintains efficient operation under varying loads while protecting against overcurrent conditions.
- Inertia & Capacity: Classified as ultra-low inertia and small capacity, this motor suits applications requiring frequent starts and stops, such as pick-and-place machines or small conveyors.
- Voltage Class: Operating within the 200VAC class, the motor integrates easily with standard industrial power supplies.
- Shaft & Brake: The standard shaft shape simplifies coupling, while the included electromagnetic brake provides reliable holding torque when de-energized.
Industry Applications
- Packaging Machinery: The HG-MR23B's rapid acceleration and precise torque control make it suitable for indexing and cut-to-length operations in packaging lines.
- Assembly Robots: Its small capacity and ultra-low inertia allow for accurate positioning in lightweight robotic arms used for component placement.
- Textile Equipment: The motor's smooth torque delivery at 3000 r/min ensures consistent thread tension and speed regulation in spinning or weaving machines.
Installation & Setup Guidance
Mount the HG-MR23B on a rigid, flat surface to minimize vibration. Use the standard shaft keyway to align with the load coupling. Ensure the electromagnetic brake wiring follows the manufacturer's polarity and voltage specifications. For optimal performance, connect the motor to a compatible Mitsubishi servo drive that matches the 200VAC class and current ratings. Verify that the ambient temperature stays within the motor's rated range to prevent overheating.
Maintenance & Reliability
From a maintenance perspective, the HG-MR23B requires minimal routine care. Inspect the electromagnetic brake periodically for wear and proper engagement. Check the motor's electrical connections for tightness and signs of corrosion. Because the motor lacks an oil seal, avoid environments with excessive moisture or particulate contamination. Keeping the motor clean and ensuring adequate airflow around the housing extends its service life and reduces unplanned downtime.
Compatibility & Integration
The HG-MR23B integrates seamlessly with Mitsubishi's MR-J4 and MR-JE series servo amplifiers. It also works with legacy MR-J3 drives when using appropriate cables. For multi-axis systems, pair this motor with a Mitsubishi motion controller to synchronize movements. Always verify the drive's firmware version supports the motor's ultra-low inertia characteristics for optimal tuning.
Selection Guide & Purchasing Advice
Before purchasing the HG-MR23B, confirm your application's torque and speed requirements match the 0.64 Nm rated torque and 3000 r/min rated speed. If you need an oil seal for harsh environments, consider alternative models. SpareTechPLC stocks this motor and can advise on compatible drives and cables.
