Motors are divided into AC motors and DC motors.
Amongthem: A rotating motor whose output or input is direct current energy is called a DC motor
A rotating motor whose output or input is AC electric energy is called AC motor.
Dc motor is divided into four kinds: series excitation, parallel excitation, other excitation, compound excitation. (Generators and motors)
Ac motors are divided into single-phase AC motors and three-phase AC motors.
Three-phase AC motor is divided into asynchronous motor and synchronous motor.
Induction motor is divided into squirrel cage type and wound type. (Electric motor)
Synchronous motors are classified into implicit pole type and salient pole type. (generator and motor) according to their functions can be divided into driving motor and control motor;
According to the type of electric energy is divided into DC motor and AC motor;
According to the relationship between the speed of the motor and the power frequency of the grid, it can be classified into synchronous motor and asynchronous motor.
According to the number of power supply phase can be classified into single-phase motor and three-phase motor;
Is motor and blower. A hair dryer is made up of a set of electric wires and a small fan. When power is on, the electric heating wire will generate heat. The wind blown by the fan will pass through the electric heating wire and become hot air. If only a small fan rotates, and the electric wire is not hot, then all that blows out is wind and not hot. The wind blown by a hair dryer belongs to dry wind. If it is used for a long time, it is easy to cause water loss and thermal damage. The secret of reducing the damage to the minimum is to pat the moisture on the hair with a towel first, comb the hair gently with your hand, and then use a hair dryer. The motor is mounted in the housing, and the blade is mounted on the shaft end of the motor. When the motor rotates, air is sucked in by the air inlet and blown out by the air outlet. The principle of controlling the wind speed is also the principle of adapting the motor speed, because the motor is the power source of the hair dryer. To change the speed of the motor, you can do it by changing the size of the coil inside the motor itself.
