HF-KN43K 400W AC Servo Motor for IMA Automatic Cutter Parts

The HF-KN43K AC servo motor is a replacement cutter part for compatible IMA automatic cutting machines.

This low inertia servo motor provides controlled rotational movement for the related machine drive mechanism. It is designed for applications that require fast response, stable speed control and accurate positioning.

The motor has a rated output of 400 W, a rated speed of 3000 rpm and a keyway shaft. It is equipped with a 17 bit encoder and does not include an electromagnetic brake.

A damaged or unstable servo motor may cause positioning errors, abnormal machine movement, servo alarms, reduced production accuracy or unexpected machine downtime.

Before ordering, please provide clear photos of the old motor nameplate, machine model, servo amplifier model and shaft connection. This information is necessary to confirm the correct cutter parts.

The HF-KN43K servo motor converts electrical control signals into accurate rotational movement.

During automatic cutter operation, the servo amplifier sends commands to the motor according to the machine control program. The encoder continuously detects motor position and speed and sends feedback to the control system.

This closed loop control allows the related cutter mechanism to operate with stable speed, accurate positioning and repeatable movement.

The low inertia design enables the motor to accelerate and decelerate quickly. This is important for automatic cutting equipment that performs frequent starts, stops and directional changes.

The exact function and installation position depend on the configuration of the IMA cutting machine. The motor may be used to drive or position one of the related machine mechanisms.

• 400 W Rated Output
  The motor provides a rated output of 400 W for the corresponding machine drive application.
• Low Inertia Design
  The low inertia rotor supports fast response during repeated acceleration and deceleration.
• Stable Speed Control
  The rated speed of 3000 rpm supports controlled and repeatable machine movement.
• Accurate Position Feedback
  The integrated 17 bit encoder provides position and speed feedback to the servo control system.
• Keyway Shaft
  The shaft includes a keyway for secure connection with the corresponding coupling, pulley or transmission component.
• No Electromagnetic Brake
  The HF-KN43K model does not include an electromagnetic holding brake. The complete model must be checked carefully because brake and non brake versions are different.
• IP65 Protection
  The enclosed motor structure provides protection suitable for normal industrial machine environments, excluding the shaft opening area.
• Reliable Replacement Solution
  Suitable for replacing an HF-KN43K motor with winding faults, encoder problems, damaged bearings, unstable rotation or mechanical damage.

• Servo amplifier alarm
• Motor cannot start
• Motor rotates intermittently
• Motor speed becomes unstable
• Positioning accuracy decreases
• Motor produces abnormal noise
• Motor temperature becomes unusually high
• Motor shaft does not rotate smoothly
• Encoder feedback becomes abnormal
• Machine movement becomes unstable
• Motor cable or encoder cable is damaged

These symptoms do not always mean that the servo motor is defective. The servo amplifier, power cable, encoder cable, machine parameters, mechanical load and power supply should also be checked.

• The motor winding is damaged
• The encoder cannot provide stable feedback
• The shaft or keyway is damaged
• The motor bearings produce abnormal noise
• The motor overheats under normal load
• The motor cannot maintain stable speed
• The housing or connector is physically damaged
• The motor cannot be repaired economically
• The machine repeatedly reports a motor related alarm

Replacing the motor without identifying the actual cause may not solve the machine problem. A complete inspection of the servo system is recommended before ordering.

Servo motors with similar appearances may have different output power, encoder types, shaft structures, brake configurations and compatible servo amplifiers.

The complete model number must be confirmed from the old motor nameplate.

Please provide the following information before ordering.

• Complete Motor Model
• HF-KN43K
• IMA Machine Model
• Machine Serial Number
• Servo Amplifier Model
• Photos of the Motor Nameplate
• Photos of the Motor Connectors
• Photos of the Motor Shaft
• Photos of the Installation Position
• Required Quantity
• Delivery Country
• City and Postal Code

Please confirm that the required model is HF-KN43K and not HF-KN43BK, HG-KN43K or another similar model.

HF-KN43K has a keyway shaft and no electromagnetic brake. A model ending with B normally indicates a brake version and cannot be treated as the same configuration without technical confirmation.

Each motor is checked according to the confirmed order information before shipment.

The inspection includes model number verification, motor appearance, shaft condition, keyway condition, connector condition and packaging.

Where test conditions are available, the motor rotation and basic operating condition can be checked before dispatch.

Product photos, nameplate photos, inspection photos and packing photos can be provided before shipment.

The motor shaft and connectors are protected carefully because collision, bending or contamination may affect installation and operation.

The servo motor is packed with protective materials to reduce the risk of impact, moisture and vibration during international transportation.

The shaft and connectors receive additional protection before the motor is placed in the export carton.

Small and urgent orders can be shipped by international express.

Medium quantity orders can be shipped by air freight.

Bulk orders can be shipped by sea freight.

The motor can also be shipped together with cables, sensors, belts, bearings, cutter blades and other cutter parts.

1. Switch off the machine and isolate the power supply before installation.
2. Record the existing servo parameters before removing the old motor.
3. Confirm that the motor model and servo amplifier are compatible.
4. Inspect the coupling, pulley, belt and mechanical load before installing the new motor.
5. Do not strike the motor shaft during installation.
6. Do not apply excessive radial or axial force to the shaft.
7. Connect the power cable and encoder cable according to the machine wiring diagram.
8. Check the grounding connection before switching on the machine.
9. Complete the required parameter setting and origin calibration after installation.
10. Run the machine at low speed first and check for alarms, abnormal noise and excessive temperature.
11. Installation and commissioning should be completed by qualified technicians familiar with servo systems and automatic cutting machines.
