Motor Temperature Talks

When the motor temperature cover exceeds the ambient temperature by more than 25 degrees, it means that the temperature rise has exceeded the normal range. Usually, the temperature rise of the motor should be controlled below 20 degrees.

Motor coils are often wound with enameled wire, and when the enameled wire is at a high temperature of more than 150 degrees, the paint film may fall off due to excessive motor temperature, resulting in a short circuit of the coil.Therefore, when the coil temperature reaches more than 150 degrees, the temperature of the motor housing is about 100 degrees, so the maximum temperature that the motor can withstand is 100 degrees.

The temperature is too high to affect How many degrees Celsius should the temperature of the motor be maintained below?What is the reason for exceeding this temperature? Answer: The temperature of the motor end cap should be below 20 degrees Celsius below the ambient temperature.The heating of the motor exceeds this temperature. It may be due to short circuit or open circuit of the coil, demagnetization of the magnetic steel, or low motor efficiency. The most common reason is that the motor is running at high current for a long time.

Common causes of fever What is the reason why the motor will heat up?How is this process carried out? Answer: When the motor is loaded and running, there will be power losses inside it. These losses will eventually be converted into heat energy, causing the motor temperature to rise beyond the surrounding ambient temperature.This increase in temperature is called the heating up of the motor.As the temperature rises, the motor needs to dissipate heat to the surrounding environment, and the heat dissipation speed is proportional to the temperature difference.

When the heat generated by the motor per unit time is balanced with the heat emitted by it, the motor temperature will remain stable, that is, it is in a state of equilibrium between heat generation and heat dissipation. When the motor is running under load, in order to give full play to its role, we hope that the greater the output power of the motor, the better (regardless of the mechanical strength limit).However, the increase in output power will also lead to an increase in power loss and temperature.Inside the motor, insulating materials such as enameled wire are the parts that are most susceptible to high motor temperature.There is a certain limit to the temperature resistance of these materials. After exceeding this limit, their physical, chemical, mechanical and electrical properties will be affected, thereby shortening their working life.

Therefore, when designing and using a motor, it is necessary to ensure that the temperature rise of the motor is controlled within the temperature resistance limit of the insulating material.After exceeding the allowable temperature of the insulating material, its life will be significantly shortened, and it may even burn out in severe cases.This temperature limit is called the allowable temperature of the insulating material, and it directly determines the allowable operating temperature of the motor.Generally, the life of the insulation material is closely related to the life of the motor.
