What is the difference between explosion-proof motor and ordinary motor

1. Different meanings:
(1) An explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric sparks during operation.
(2) Motor (English: Electric ** chinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction.
2. Different uses:
(1) Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.
(2) Ordinary motors cannot be used in flammable and explosive situations.
3. Different categories:
(1) Explosion-proof motor:
① According to the principle of the motor:
It can be divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof DC motor.
② According to the place of use:
It can be divided into explosion-proof motors for underground coal mines and explosion-proof motors for factories.
③ According to the principle of explosion-proof:
It can be divided into flameproof motor, increased safety motor, positive pressure motor, non-sparking motor and dust explosion-proof motor.
(2) Ordinary motor:
① According to the type of working power supply: it can be divided into DC motor and AC motor.
② According to the structure and working principle, it can be divided into: DC motor, asynchronous motor and synchronous motor.
③ According to the starting and running mode, it can be divided into: capacitor starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting running single-phase asynchronous motor and split-phase single-phase asynchronous motor.
④ According to the application, it can be divided into: drive motor and control motor.
⑤ According to the structure of the rotor, it can be divided into: squirrel induction motor (the old standard is called squirrel cage asynchronous motor) and wound rotor induction motor (the old standard is called wound asynchronous motor).
⑥ According to the operating speed, it can be divided into: high-speed motor, low-speed motor, constant-speed motor, and speed-regulating motor. Low-speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors and claw-pole synchronous motors.
