What are the causes of Roots blower motor overload?

As a mechanical engineer of fan manufacturer, I have designed and maintained Roots blower.

In these years, I found that overload of Roots blower motor is a common problem.

Next, I will introduce the cause of overload of Roots blower motor in detail.

First, the overload of Roots blower motor may be caused by too high or too low voltage.

When the voltage is too high, the motor will generate too much heat, which will lead to motor overload.

On the contrary, when the voltage is too low, the motor needs more current to operate, which will also lead to motor overload.

Therefore, in order to avoid motor overload, we need to ensure that the voltage is within the normal range.

Secondly, the overload of Roots blower motor may be caused by the failure of overload protection device.

Overload protection device is a device used to protect the motor. When the motor exceeds the rated load, it will automatically cut off the power supply.

However, if the overload protection device fails, the motor cannot operate normally, which will lead to motor overload.

Therefore, we need to regularly check and maintain the overload protection device to ensure that it can work properly.

Thirdly, the overload of Roots blower motor may be caused by mechanical failure.

The mechanical parts of Roots blower, such as bearings and gears, often rotate at a high speed. If these parts fail, the motor will be overloaded.

Therefore, we need to regularly check and maintain the mechanical parts of Roots blower to ensure that they can operate normally., Overload of Roots blower motor may be caused by excessive load.

If the load carried by Roots blower exceeds its rated load, the motor will be overloaded.

Therefore, we need to ensure that the load of Roots blower is within its rated load range.

In a word, the overload of Roots blower motor is a common problem, but we can prevent and solve this problem by checking and maintaining the voltage, overload protection device, mechanical parts and loads.

During the maintenance of Roots blower, we should fully understand the causes of motor overload, take effective measures to avoid this problem, and ensure the stable operation of Roots blower.
