The temperature rise of a motor generally refers to,Three-phase asynchronous motorIn the rated operating state, the temperature of the motor stator winding is higher than the ambient temperature value, generally speaking, the ambient temperature is specified as35℃-40℃Below, if the nameplate is not marked with a specific value, the default is40℃.

       likeThree-phase asynchronous motorThere are also cold and hot states, and cold means that the motor stops running4Hours or run no more1Hour, this time to remember the temperature and the ambient temperature compared to each other is not exceeding3℃; The hot state is the situation except the cold state, which is called the hot state;

       Many manufacturers put equipment into the ambient temperature greater than or close to it in the summer40℃If the three-phase asynchronous electric motor runs at full load in such an ambient temperature for a long time, it is easy to cause the motor temperature rise, and the surface temperature can be reached80℃It is easy to cause the motor to burn, soThree-phase asynchronous motor manufacturersMori motor still recommends that the ambient temperature is greater than40℃When running in the environment, remember to use physical cooling of the motor to prevent the motor burning accident.
