There are many types of electric motors. Do you know which classifications are clear? What criteria are used to classify? Dalan Motor tells you the specific classification is as follows: 1. According to the working power classification, it can be divided into DC motor and AC motor according to the different working power of the motor. Among them, the AC motor is also divided into a single-phase motor and a three-phase motor. 2, according to the structure and working principle classification According to the structure and working principle can be divided into DC motor, asynchronous motor and synchronous motor. Synchronous motors can also be classified into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. 1 induction motor is divided into three-phase asynchronous motor and shaded pole asynchronous motor. 2 AC commutator motor is divided into single-phase series-excited motor, AC-DC dual-purpose motor and repeller motor. 3. Classification according to starting and running mode According to the starting and running modes, it can be divided into capacitive starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting-operated single-phase asynchronous motor and split-phase single-phase asynchronous motor. 4. Classification by purpose Motors can be divided into drive motors and control motors according to their applications. The drive motor is further divided into a motor for a power tool, a motor for home appliances, and other motors for general-purpose small-sized mechanical equipment. The control motor is further divided into a stepping motor and a servo motor. 5. According to the structure classification of the rotor, the structure of the rotor can be divided into a squirrel-cage asynchronous motor and a wound-type asynchronous motor. 6, according to the operating speed classification according to the operating speed can be divided into high-speed motor, low-speed motor, constant speed motor, speed control motor. 7, according to the protection type classification according to the protection type can be divided into open, closed, waterproof, watertight, submersible and explosion-proof. According to its ventilation protection structure, it is divided into mesh cover type, anti-drip type and splash-proof type. 8, according to ventilation cooling classification according to ventilation cooling methods can be divided into self-cooling, self-fan cooling, his fan cooling, pipeline ventilation, liquid cooling, closed loop gas cooling, surface cooling and internal cooling. 9. According to the installation structure type, the motor installation type is usually indicated by code. The code number is represented by the abbreviation IM of the international installation. The first letter in IM indicates the installation type code, B indicates the horizontal installation, V indicates the vertical installation, and the second digit indicates the feature code, which is represented by Arabic numerals. 10. According to the classification of insulation grade, it can be divided into A grade, E grade, B grade, F grade, H grade and C grade according to insulation grade. 11. According to the rated working system, the rated working system can be divided into continuous working system, intermittent working system and short working system. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn
