Description

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.

Features

Low-Inertia Rotor: Tailored for dynamic, high-frequency positioning sequences.
Electromagnetic Brake: Integrated holding brake ensures secure shaft locking during power-down states or safety stops.
Shaft Oil Seal: Provides robust mechanical protection against fluid and lubricant ingress at the output shaft interface.
Optimized Insulation: Built to Insulation Class 130 (B) specifications for thermal endurance.
High Torque Output: Delivers a peak torque capability of up to 4.5 N.m for demanding acceleration curves.

Applications

Multi-axis Cartesian robotics and handling systems.
High-speed packaging, labeling, and sorting machinery.
Semiconductor fabrication systems and electronic component inserters.
Precision X-Y motion tables and machine tool auxiliary axes.

Empirical Engineering Insights

Alternative Models & Compatibility

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.

Application Pitfalls & Engineering Notes

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.

Commissioning & Wiring Tips

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.

Installation Guidelines

CRITICAL WARNING: ELECTRICAL & KINETIC SAFETY

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.

Mechanical Alignment: Securely bolt the motor flange to the mounting plate. Ensure correct alignment with the driven shaft using a flexible coupling to minimize radial and axial load stresses.

Cable Routing & Grounding: Route separate encoder and power cables. Maintain physical separation between power conductors and signal feedback loops to prevent electromagnetic interference.

Brake Power Integration: Wire the 24V DC electromagnetic holding brake circuit through a dedicated relay controlled directly by the servo amplifier's brake output signal.

Key Features:

Can the electromagnetic brake on the HG-KR43BJ be used for dynamic deceleration?

No. The built-in mechanical brake is strictly designed as a holding brake when the shaft is stationary. Using it for dynamic braking during high-speed rotation will cause severe friction wear and premature brake failure.

Which servo amplifier series is compatible with this model?

The HG-KR43BJ motor is optimized for use with Mitsubishi Electric MELSERVO-J4 series drives, specifically 400W units such as the MR-J4-40A or MR-J4-40B.

What is the primary operational environment limitation for the HG-KR43BJ?

This servo motor must be installed indoors, free from direct sunlight, corrosive or flammable gases, oil mist, high-density dust, and excessive vibration to preserve the insulation and seal integrity.
