Operating as a high-precision rotary drive within automated industrial networks, the Mitsubishi Electric HG-KR43BJ delivers low-inertia performance optimized for rapid acceleration and deceleration cycles. This 0.4 kW motor belongs to the low-inertia, small-capacity HG-KR series and features an integrated electromagnetic brake and a specialized oil seal to support high-duty machine operations. Engineered to pair with MELSERVO-J4 amplifiers, it provides reliable closed-loop feedback and precise speed control up to a rated 3000 r/min.
| Parameter | Value |
|---|---|
| Manufacturer | Mitsubishi Electric |
| Model Number | HG-KR43BJ |
| Motor Series | HG-KR (Low inertia, small capacity) |
| Rated Output Power | 0.4 kW (400 W) |
| Rated Speed | 3000 r/min |
| Rated Current | 2.6 A |
| Maximum Torque | 4.5 N.m |
| Electromagnetic Brake | Equipped (Holding Brake) |
| Oil Seal | Equipped |
| Insulation Class | 130 (B) |
| Vibration Rank | V10 |
| Environmental Constraints | Indoor installation, free of corrosive gas, flammable gas, oil mist, and dust |
| Net Motor Weight | 1.8 kg |
| Shipping Weight (Calculated) | 3.0 kg |
| Connection Interface | Description / Assignment |
|---|---|
| Power Connector | U, V, W, and PE grounding terminals for motor phase excitation. |
| Brake Terminals | Dedicated DC holding brake power supply leads (non-polarized). |
| Encoder Interface | High-resolution absolute/incremental serial encoder output connection. |
The HG-KR43BJ functions as a direct successor to legacy HF-KP series motors of equivalent physical sizing. When migrating to the HG-KR range, confirm that your MR-J4 series amplifier firmware is fully updated. Verify mounting configurations, as shaft and flange alignment profiles remain matched with previous generations, but encoder communication protocols require compatible MR-J4-40A/B drive platforms.
The built-in electromagnetic brake is designed exclusively as a static holding brake. It is critical to avoid utilizing this brake for dynamic deceleration or emergency stopping during shaft rotation, as rapid friction wear will compromise holding torque. Always program the servo drive to ramp speed down to zero before applying the mechanical brake contactor.
Ensure the motor frame is grounded via a dedicated low-impedance ground conductor back to the servo drive PE terminal to mitigate high-frequency PWM switching noise. If operating in environments with intermittent mist, configure the motor cabling to include a drip loop so that fluids run away from the connector entry points, preserving the integrity of the oil seal.
Disconnect all incoming electrical power supplies to both the servo drive and the auxiliary holding brake circuits before attempting any wiring or mechanical mounting procedures. Verify that drive bus capacitors have fully discharged prior to handling output phase cables. Lock out/tag out (LOTO) procedures must be followed strictly.
