1、 Motor malfunction

1. Motor damage

Due to the frequent use of industrial fans, motors are often one of the components that are prone to problems. Common motor faults include motor damage, motor overheating, and motor bearing wear. When the motor cannot start normally or emits abnormal noise, it is likely that the motor itself is damaged. At this time, the motor needs to be replaced or repaired.

2. Motor overheating

Long term work or overload can cause the motor to overheat, thereby damaging the motor winding and insulation materials. If the motor is found to be overheated, the use of industrial fans should be stopped immediately, and inspection and maintenance should be carried out after the motor cools down.

2、 Power failure

1. Power line failure

A power line malfunction may cause the motor to malfunction or damage the motor. During use, it is necessary to regularly check whether the power circuit is in good contact and replace the aging power circuit in a timely manner.

2. The power supply voltage is too high or too low

High or low power supply voltage can have an impact on the operation of industrial fans, and even lead to motor damage. At this time, it is necessary to promptly check whether the power supply voltage is normal and take measures to ensure the stability of the power supply voltage.

3、 Mechanical failure

1. Damaged fan blades

Fan blades are an important component of industrial fans. Damaged blades can reduce the speed of industrial fans and lead to increased noise. Timely replacement of damaged blades can effectively avoid continuous damage.

2. Micro switch malfunction

The micro switch of an industrial fan is a key component that controls the start stop and reverse rotation of the fan. If the micro switch malfunctions, it may cause the fan to malfunction. At this time, it is necessary to check whether the micro switch is loose or damaged, and replace it in a timely manner.
