• Torque Capabilities: Rated torque is 2.4 Nm, with a maximum torque of 7.2 Nm, giving the motor substantial load-handling capacity during peak demands.
• Current Ratings: The HG-MR73 draws a rated current of 5.8 A and can handle a peak current of 20 A, ensuring stable performance under varying loads.
• Load Ratings: Maximum radial load is 392 N and maximum axial load is 147 N, allowing the motor to support external forces without compromising performance.
• Operating Temperature: The motor operates reliably in temperatures from 32 to 104 degrees Fahrenheit, suitable for typical industrial environments.

Industry Applications

Engineers often face the challenge of integrating a motor that balances speed, torque, and size.

• Pick-and-Place Systems: The rapid acceleration and deceleration enabled by ultra-low inertia reduce cycle times, improving throughput.
• Packaging Machinery: The compact 750-watt output and high maximum speed (6000 RPM) allow for precise control in high-speed packaging lines.
• Robotics: The motor's torque-to-weight ratio supports dynamic movements in robotic arms without sacrificing stability.

Installation & Setup Guidance

Mounting the HG-MR73 is straightforward with its standard straight shaft design. Ensure the motor is securely fastened to a rigid base to minimize vibration. When connecting to a compatible servo drive, verify that the voltage class matches your system (200VAC class). Always follow the manufacturer's wiring diagrams to avoid electrical issues.

Maintenance & Reliability

To maximize the service life of the HG-MR73, perform periodic inspections of the shaft and bearings. Check for unusual noise or vibration, which may indicate wear. Keep the motor clean and within the specified operating temperature range (32 to 104 degrees Fahrenheit). Regular maintenance reduces unplanned downtime and extends motor life.

Compatibility & Integration

Its standard straight shaft design simplifies coupling to mechanical loads. For best performance, pair it with a drive that can supply the required peak current of 20 A.

Selection Guide & Purchasing Advice

Before ordering the HG-MR73, verify your system's voltage class (200VAC) and torque requirements. The motor's rated torque of 2.4 Nm and peak torque of 7.2 Nm should match your load profile.
