What is the meaning of the motor from cold and cold?
Motor self-cooling refers to the wind blade of the rotor, which starts cooling during the operation of the motor. The motor is cooled by an electric motor plus cooling fan. Normal three-phase ac asynchronous motors are used for cold, and it is very cold when it is unable to heat the electric motors and heat the heat. Such as frequency conversion motor, dc motor, etc., normally use force cooling.
Self-cooling: the surrounding environment, and the holes in the ends of the cover, reduce the temperature of the motor Forced cooling: other help For example: add a fan to the shaft The channel is designed to reduce the temperature through the flow of cold water The oil in the transformer is cold
Self-cooling is an unsubsidized cooling device that allows the heat to spread through the air or other media. Strong cold is forced cooling, with auxiliary heat sinks, keeping the temperature within a certain range
