Motor, also called the motor, it is a kind of realization of electrical energy into mechanical energy by electromagnetic effect, because electricity has several forms, the mechanical structure is different also, also can have different magnetic field forms, the purpose of the motor itself places also have differences, there are many kinds of types, so electricity opportunities according to different standards, there will be not the same as the name and category.
First, through the form of electrical energy to be divided
1, electricity has two forms of AC and DC, so the motor can be generally divided into AC motor and DC motor two categories; 2, alternating current has two kinds of single-phase and three-phase, single-phase alternating current motor and three-phase alternating current motor; 3. Voltage has high and low voltage levels, so there are also high voltage motors and voltage motors.
Two, according to the principle of classification
1, according to the different slip rate, can be divided into synchronous motor and asynchronous motor; 2, synchronous motor according to the magnetic field is not the same, there are permanent magnet synchronous motor, hysteresis synchronous motor and reluctance synchronous motor; 3, asynchronous motor, induction form, also have the form of AC commutator. Induction in the form of three-phase asynchronous motor and cover pole asynchronous motor. Ac commutator motor, also divided into repulsion motor, series motor.
Three, according to the structure of the classification
1, the rotor structure is not the same, there are wound rotor motor and squirrel cage rotor motor, as well as permanent magnet rotor motor; 2. According to the different positions of the rotor and stator, it can be divided into inner rotor motor and outer rotor motor; 3. According to whether there is a carbon brush, it can be divided into brush motor and brushless motor; 4, brush motor with permanent magnet brush and electromagnetic DC motor; 5, DC motor according to the excitation form, can be divided into other excited, series excited, shunt excited and compound excited concentrated form; 6, according to the magnetic material is not the same, there are ferrite motor, rare earth permanent magnet electric and aluminium-nickel-cobalt permanent magnet motor.
Four, according to the speed of different classification
1, speed has high or low, so there are high speed motor, low speed motor, constant speed motor, speed motor; 2. According to the number of poles, there are 2 poles, 4 poles, 8 poles, 16 poles, 32 poles and other motors; 3, low speed motor, torque motor, deceleration motor, direct drive motor, claw pole synchronous motor.
Five, according to the use and use of distinction
1. According to the operation point, it can be divided into power motor and control motor; 2. According to different running modes, it can be divided into direct starting motor, soft starting motor and speed regulating motor; 3, control motor, servo motor and stepper motor.
