How to solve the problem of industrial fan motor?

Verify Power Supply: Ensure that the motor is receiving a proper power supply. Check for tripped circuit breakers, blown fuses, or any other electrical issues. Verify that the voltage and phase of the power supply match the motor's requirements.

Inspect Wiring and Connections: Examine the motor's wiring and connections. Look for any loose, damaged, or disconnected wires. Tighten loose connections and replace any damaged wiring. Pay special attention to the motor's terminal box and junction box.

Motor Overload Protection: Many industrial motors have built-in overload protection. Check if the motor has an overload relay or thermal protector. If it has tripped, allow it to cool down and reset it according to the manufacturer's instructions.

Lubrication: If the motor has oil ports, make sure they are properly lubricated according to the manufacturer's recommendations. Lack of lubrication can cause motor overheating and poor performance.

Check for Mechanical Issues: Inspect the fan blades, bearings, couplings, belts, and pulleys for any signs of damage, misalignment, or excessive wear. Replace or repair any worn or damaged components as needed.

Test Run Capacitors: If the motor uses a capacitor, test it with a multimeter to ensure it is functioning properly. Replace the capacitor if it is faulty.

Motor Temperature: Monitor the motor's temperature during operation. Overheating can be a sign of a problem. Check if the cooling system, such as fans or vents, is functioning correctly.

Consult Manufacturer or Technician: If the above steps do not resolve the issue, consult the motor's manufacturer or contact a qualified technician who specializes in motor repair. They can provide further guidance and assistance in diagnosing and repairing the motor problem.
