What is the classification of ac motor?
The three-phase asynchronous motor is the most widely used in the two kinds of rat cage and winding type according to the different rotor structure.
According to the number of different ac power, and can be divided into two major categories of single-phase and three-phase ac motor, is currently the most widely used three-phase asynchronous motor, this is because the three-phase asynchronous motor has simple structure, low cost, strong and durable, convenient in operation and maintenance, etc. A single phase asynchronous motor is widely used in situations where there is no three-phase power supply and some small motors
According to the principle, the ac motor can be divided into two categories, synchronous motor and asynchronous motor, synchronous motor rotation speed and the frequency of the ac power source has a strict corresponding relation, in the running speed strictly keep constant; The speed of the asynchronous motor changes slightly as the load changes.
