The phenomenon of electromagnetic i

The phenomenon of electromagnetic induction motors is implemented based on a mechanical conversion between electrical energy and converting the mechanical energy and electric energy, comprising a rotary motor and a transformer into two categories. The rotary electric machine is an electromechanical energy conversion device, it is mainly used as a generator, the mechanical energy into electrical energy; or as a motor, the electrical energy into mechanical energy. Some also used as condensers motor for improving the power factor of the grid. In addition, micro-motor, widely used in automatic control systems. Electrical power conversion means is a transformer is no relative motion between the components, it is widely used in conversion and power transmission circuit isolation, voltage, current, impedance. In October 1831, Faraday created the first model of the induction generator. Since then, the study of electricity that has developed rapidly. Thereby promoting the development of electrical appliances. For the motor, the current is more commonly the main AC motor, it can be divided into two types: 1, three-phase asynchronous motors. 2, single-phase AC motor. The first is used in the industry, while the second is used in consumer electronics. The following three-phase asynchronous motor example to explain the basic working principle.
