Product Description

Optimizing dynamic response in high-performance motion control systems, the Mitsubishi Electric HG-KR73BJ AC Servo Motor provides precise positioning capability within the MELSERVO-J4 automation platform. This low-inertia, small-capacity rotary motor is engineered with an integrated electromagnetic brake and a factory-installed oil seal, making it highly suited for vertical axis applications and environments requiring protection against fluid ingress.

Key Features

  • Low Inertia Design: Optimized for high-frequency positioning cycles and rapid acceleration/deceleration profiles.
  • Electromagnetic Holding Brake: Integrated brake (B-suffix) ensures secure position retention during power-off states, preventing vertical axis drop.
  • Integrated Oil Seal: Factory-fitted shaft oil seal (J-suffix) prevents gear lubricant or cutting fluid migration into the motor housing.
  • High-Resolution Feedback: Compatible with absolute/incremental encoders to deliver sub-micron positioning accuracy.
  • Industrial Protection: Designed to withstand challenging industrial environments when paired with appropriate IP-rated cabling.

Typical Applications

  • Vertical axis drive systems requiring safety holding brakes.
  • Packaging, filling, and sealing machinery.
  • High-speed material handling gantries and pick-and-place systems.
  • Semiconductor manufacturing and PCB assembly equipment.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-KR73BJ is designed for direct pairing with the MR-J4-70A, MR-J4-70B, or MR-J4-70GF servo amplifiers. When migrating from legacy HF-KP series motors, note that parameter adjustments are required in MR Configurator2 to accommodate the higher-resolution encoder feedback and different physical inertia ratios.

Application Pitfalls & Engineering Notes

The integrated electromagnetic brake is strictly a holding brake and must never be used for dynamic deceleration or emergency stopping of moving loads. Repeated dynamic braking cycles will wear out the friction plates, leading to holding failure. Ensure the control sequence releases the brake prior to enabling the servo amplifier drive stage.

Commissioning & Wiring Tips

Always route the encoder feedback cable separately from the high-voltage motor power and brake cables to prevent electromagnetic interference. Ensure the motor frame is grounded directly to the servo amplifier's protective earth (PE) terminal to eliminate high-frequency noise currents.

Installation Guidelines

CRITICAL WARNING

Ensure all main power sources are completely de-energized and locked out before attempting installation or maintenance. Wait at least 15 minutes for the servo amplifier's internal bus capacitors to discharge fully. Verify zero voltage across the terminals before handling connections.

1

Mount the motor securely to a rigid machine base using the specified flange mounting bolts, ensuring correct alignment with the driven shaft to prevent premature bearing wear.

2

Connect the motor power, electromagnetic brake, and encoder cables, ensuring all connectors are fully seated and locked to maintain environmental protection ratings.

3

Configure the servo amplifier parameters to match the HG-KR73BJ motor profile, and perform a low-speed test run to verify rotation direction and brake operation before full commissioning.

FAQ
Can the electromagnetic brake on the HG-KR73BJ be used to stop a moving load?
No. The integrated brake is designed strictly as a holding brake to maintain position when the motor is de-energized. Using it to decelerate or stop a moving load will cause rapid wear and failure of the internal friction plates.
What is the purpose of the 'J' suffix in the HG-KR73BJ model number?
The 'J' suffix indicates that the motor is equipped with a factory-installed shaft oil seal. This prevents oil, gear lubricants, or cutting fluids from entering the motor housing through the shaft interface.
Which servo amplifiers are compatible with the HG-KR73BJ motor?
This motor is fully compatible with the Mitsubishi Electric MELSERVO-J4 series amplifiers, specifically the MR-J4-70A, MR-J4-70B, and MR-J4-70GF models.
What are the environmental installation requirements for this motor?
The motor should be installed indoors, away from direct sunlight, in an environment free from corrosive or flammable gases, heavy oil mist, excessive dust, and dirt. Operating ambient temperature should be between 0 and 40 degC.
