Motor is an indispensable and important equipment in modern industry, widely used in machinery, electricity, transportation and other fields. However, during the operation of the motor, the temperature may be too high. If measures are not taken in time, it will have a serious impact on the normal operation of the motor, and even lead to equipment failure, which will affect the production efficiency. In this paper, the consequences, hazards and preventive measures of excessive motor temperature will be introduced in detail.

First, the consequences of too high motor temperature

When the motor runs for a long time or the load is large, the motor temperature may be too high. Too high motor temperature will have the following adverse effects on the motor:

1. Aging of motor windings: too high motor temperature will lead to aging of insulation layer of motor windings, which will cause cracking of insulation layer for a long time, resulting in short circuit, grounding and other faults, which seriously affect the service life of the motor.

2 motor bearing damage: the motor temperature is too high will also lead to motor bearing damage, bearing poor lubrication will make the motor noise increase, and even lead to bearing rust, and then cause motor bearing damage.

3. Motor power decline: too high motor temperature will cause the magnetic field inside the motor to change, resulting in a decrease in the power of the motor.

Second, the harm of excessive motor temperature

Excessive motor temperature will cause serious harm to the motor, mainly in the following aspects:

1. Reduce the service life of the motor: too high motor temperature will lead to aging of the insulation layer of the motor winding, thereby reducing the service life of the motor.

2, increase the motor failure rate: the motor temperature is too high will lead to the aging of various components inside the motor, the failure rate will increase.

3. Increase maintenance costs: too high motor temperature will lead to the aging of various parts inside the motor, increasing maintenance costs.

Third, the motor temperature is too high preventive measures

In order to prevent the motor temperature from being too high, we can take the following measures:

1. Reasonable selection of the motor: the model and specification of the motor should be reasonably selected according to the actual load situation to avoid overload during the operation of the motor.

2. Improve the ventilation and heat dissipation performance of the motor: the motor should be installed in a well-ventilated and suitable temperature position as far as possible to facilitate heat dissipation. At the same time, equipment such as radiators should also be installed to enhance the heat dissipation effect of the motor.

3. Regular maintenance: For the motor, regular maintenance should be carried out, such as replacing lubricating oil, cleaning ventilation holes, etc., to ensure the normal operation of the motor.

4. The use of temperature control device: During the operation of the motor, the temperature control device can be used to ensure the normal operation of the motor by controlling the temperature of the motor.

Too high motor temperature will seriously affect the normal operation of the motor, and even affect the production efficiency. Therefore, we should take a series of measures to ensure the normal operation of the motor. In practical use, we should strengthen the maintenance of the motor, reasonable selection of motor models and specifications, improve the ventilation and heat dissipation performance of the motor, the use of temperature control devices and other measures to ensure the normal operation of the motor.
