The feed motor of the feed extruder is not turning. How should I troubleshoot and repair it?

 

 

The feed motor of the extruder (the motor that drives the feeder) suddenly stops turning, the feeder stops, and the extruder cannot produce normally. Many people assume that the motor is burnt out and directly replace the motor, which costs a lot of money. In fact, sometimes it is just a loose wire or a broken switch, which can be repaired with a simple check.

 

 

1.Check for power supply:
First, check if the main circuit breaker in the workshop has tripped. If it has, reset it (before resetting, check for short circuits, such as burnt wires);Next, check the power plug or terminals of the feeder. If they are loose or disconnected, tighten them or make sure the screws are secure; Use a multimeter (or test pen) to test the motor's power cord to see if there is power (the test pen lights up if there is power, otherwise there is no power). If there is no power, contact an electrician to repair the wiring;

 

2. Check for faulty switches: If there is power, check the feeder's switches (such as push-button switches or knife switches). Press the switch and listen for a "click" sound. If there is no sound, the switch may be faulty. Try replacing it with a new switch (choose the same model as the original, such as 220V or 380V). Before replacing, be sure to disconnect the power and connect the switch wires correctly (live wire to L, neutral wire to N).

 

3. Check for motor overload: The motor usually has an overload protection switch (like a small red button). If the motor doesn't turn for too long, the protection switch will trip. Press it to reset. After resetting, manually turn the feeder's pulley to see if it can turn (if it can't turn, the feeder may be stuck; clear any obstructions and try again).

 

4. Check if the motor is burnt out: If everything above is fine, smell the motor for a burnt smell and touch the motor casing (don't touch it when it's too hot). If there's a burnt smell or the casing is very hot, the motor coils may be burnt out. You can't repair this yourself; find a professional electrician to disassemble and repair the motor, or replace it with a new one (when replacing, pay attention to the motor's power; make sure it's the same as the original, for example, replace a 1.5kW motor with a 1.5kW one).

 

 

1. After repair, run the motor under no-load for 30 seconds, listening for any abnormal noises and checking for smooth operation. If everything is fine, then connect the feeder.

 

2. To prevent motor failure: Do not allow the feeder to stall for extended periods (stop the machine immediately if it stalls). Regularly lubricate the motor bearings (every 3 months). Avoid overloading the motor.
