This low inertia motor enables quick acceleration and deceleration, making it suitable for applications requiring frequent starts and stops.
Industry Applications
The HG-KR053BJ excels in several automation scenarios:
- Pick-and-Place Systems: Its low inertia and 3,000 RPM speed allow rapid positioning of lightweight components. The built-in brake holds the load securely when power is removed, preventing drift.
- Packaging Machinery: The IP65 rating protects against dust and moisture common in packaging lines. The 22-bit encoder ensures precise registration for labels or film cutting.
- Assembly Stations: With 0.16 Nm torque and 50W output, this motor drives small indexing tables or screwdrivers reliably. The electromagnetic brake adds a safety layer during maintenance stops.
Installation & Setup Guidance
Mount the HG-KR053BJ using the standard straight shaft for direct coupling to loads. Connect via the 4-pin rectangular connector, ensuring proper alignment. Verify the supply voltage matches the 200 Volts AC class. For optimal performance, use a compatible Mitsubishi servo drive. Do not exceed the rated current of 0.9 Amps. Ensure the motor is securely grounded and the brake wiring is correctly terminated to function as intended.
Maintenance & Reliability
Regularly inspect the motor and brake for signs of wear or contamination. The IP65 enclosure reduces the need for frequent cleaning, but verify that seals remain intact in harsh environments. Periodically test the electromagnetic brake operation to confirm holding torque. Monitor the encoder feedback for position accuracy. Following these steps extends service life and minimizes unplanned downtime.
Comparison with Similar Models
When selecting a servo motor, consider how the HG-KR053BJ compares to other small-capacity options:
| Feature | HG-KR053BJ | Typical 50W Motor without Brake |
|---------|------------|----------------------------------|
| Brake Type | Built-In Electromagnetic Brake | None (external brake required) |
| Encoder Resolution | 22-Bit | Often 17-Bit or lower |
| IP Rating | IP65 | IP20 or IP40 |
| Inertia | Low Inertia | Low or Medium Inertia |
| Connector | 4-Pin Rectangular | Varies (often circular) |
The integrated brake simplifies system design and reduces external component costs. The higher encoder resolution improves positioning accuracy for demanding tasks.
Selection Guide & Purchasing Advice
Before purchasing the HG-KR053BJ, verify that your application requires a built-in electromagnetic brake and direct drive (no reduction gear). Confirm the supply voltage is 200 Volts AC and the rated current does not exceed 0.9 Amps. Ensure the mating connector matches the 4-pin rectangular type.
