The temperature of a motor usually depends on its type and design. Generally speaking, if the insulation level of the motor is Class A and the ambient temperature is 40 ℃, the temperature of the motor casing should not exceed 60 ℃, and the temperature limits of each part of the motor should be met. The temperature of rolling bearings should not exceed 95 ℃, and the temperature of sliding bearings should not exceed 80 ℃. Excessive temperature can cause changes in oil quality and damage the oil film. In practice, the temperature of the chassis is often based on not being hot to the touch. The surface of the squirrel cage rotor has significant stray losses and high temperatures, generally limited to not endangering adjacent insulation. It can be estimated by applying irreversible color changing paint in advance.

In order to ensure the normal operation of the motor, the following points need to be noted:

1. Avoid overload: Overload can cause the temperature of the motor to rise, affecting its performance and lifespan.

2. Environmental temperature: Both high and low environmental temperatures can affect the temperature of the motor, so it is necessary to use the motor in a suitable environment.

3. Heat dissipation: The heat dissipation system of the electric motor needs to operate normally to avoid excessive temperature.

The temperature of the motor is crucial for its normal operation. Regularly checking the temperature of the motor and ensuring it is within the normal range can avoid potential problems.
