Motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. Its main function is to convert mechanical energy into electrical energy and generate driving torque, which is used as the power source of electrical appliances or various machines.
At present, the most commonly used is to use heat energy and water energy to drive the generator rotor to generate electricity. With the maturity of wind power generation technology, wind power generation has gradually entered our lives. Classification of working power supply: it can be divided into DC motor and AC motor. DC motor is a kind of motor running on DC working voltage, which is widely used in tape recorders, video recorders, DVD players, electric razors, hair dryers, electronic watches, toys and so on.
