Product Description

Description

Engineered for high-performance dynamic positioning in space-restricted industrial environments, the Mitsubishi Electric HC-UF43K is a flat-type, low-inertia AC servo motor. This unit integrates into the MELSERVO system architecture, offering precise angular velocity and torque control. The low-profile mechanical design of the HC-UF43K makes it an ideal choice for machinery requiring high torque density without increasing the physical footprint. Equipped with a keyed shaft configuration, this motor ensures slip-free torque transmission during rapid acceleration and deceleration cycles.

Key Features

  • Flat Profile Design: Specifically configured for applications with limited depth or compact mounting envelopes.
  • Low Inertia Rotor: Optimized for high-frequency start-stop cycles and highly dynamic positioning tasks.
  • Integrated Keyway: Features a factory-machined keyway (HC-UF series specification with key) for positive-lock shaft coupling.
  • Industrial Grade Insulation: High-integrity winding insulation designed to withstand transient voltage spikes from modern servo drives.

Applications

  • Material handling systems and multi-axis Cartesian pick-and-place robots.
  • Compact packaging machines, indexing tables, and textile machinery.
  • Semiconductor manufacturing equipment and wafer-handling automation.

Technical Specifications

Parameter Value
Manufacturer Mitsubishi Electric
Model Number HC-UF43K
Motor Series HC-UF Series (Flat Type)
Rated Output 0.4 kW (400 W)
Rated Speed 3000 r/min
Shaft Type With keyway (Includes key)
Motor Mass 1.7 kg (3.7 lbs)
Shipping Weight (Calculated) 2.7 kg (5.95 lbs)

Alternative Models & Compatibility

The HC-UF43K AC servo motor is designed for native integration with MR-J2S series servo amplifiers (specifically the MR-J2S-40A and MR-J2S-40B modules). When upgrading legacy motion systems, verify that the amplifier firmware is compatible with HC series motors. Note that physical replacements must maintain exact mounting dimensions, as flat-type motors feature a distinct bolt circle diameter compared to standard cylindrical models.

Application Pitfalls & Engineering Notes

Because flat-profile motors have a reduced external surface area, heat dissipation is highly dependent on conductive cooling through the mounting face. Ensure the motor is bolted directly to a clean, unpainted metal surface (such as an aluminum frame) of sufficient mass to serve as an effective heat sink. Additionally, avoid exceeding the maximum radial and axial load limits on the shaft, as flat-motor bearings are sensitive to overhung loads which can cause premature wear and encoder alignment drift.

Commissioning & Wiring Tips

To avoid high-frequency noise interference in the encoder signal line, always use double-shielded twisted-pair cabling for the encoder feedback loop. Ground the cable shield at the servo amplifier chassis side only. If experiencing "AL.16" or "AL.20" fault codes on your MR-J2S drive, check the integrity of the encoder connector plug pins and ensure no moisture has entered the motor terminal housing during installation.

Installation Guidelines

CRITICAL WARNING: Prior to commencing any mechanical installation or electrical wiring, ensure all primary three-phase power supplies to the associated servo amplifier are locked out and tagged out. Verify that the intermediate DC bus capacitors have completely discharged (wait at least 15 minutes after power-down) before touching any electrical terminals to prevent high-voltage shock hazards.
1
Align the motor shaft precisely with the load shaft using a flexible coupling to minimize radial and axial forces during operation.
2
Mount the motor securely to the machine base frame, ensuring clean metal-to-metal contact for optimal heat conduction.
3
Connect the power and encoder feedback cables, ensuring all circular connectors are fully seated and locked to maintain environmental sealing.

FAQ
Which servo amplifier series is compatible with the HC-UF43K?
This motor is designed to pair with Mitsubishi Electric MR-J2S series servo drives, specifically the 400W rated MR-J2S-40A and MR-J2S-40B models.
What is the physical advantage of the HC-UF series compared to the HC-KFS series?
The HC-UF series features a flat-type motor envelope, which significantly reduces the mounting depth required compared to standard cylindrical motors like the HC-KFS series, making it ideal for tight spaces.
Does the HC-UF43K include a shaft key?
Yes, the 'K' suffix in the model designation indicates that the shaft is manufactured with a standard keyway and includes the matching shaft key.
What precautions should be taken to prevent thermal issues?
Ensure the motor is mounted to a metal surface of adequate size (such as an aluminum plate) to act as a heat sink, and ensure there is sufficient ambient airflow around the motor body.
