1. Different meanings:

(1) An explosion-proof motor is a type of motor that can be used in flammable and explosive places and does not produce sparks during operation.

(2) Motor (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on 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, city gas, transportation, grain and oil processing, papermaking, medicine and other sectors. 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 motor principle:

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 coal mines and explosion-proof motors for factories.

③ According to the explosion-proof principle:

It can be divided into flameproof motors, increased safety motors, positive pressure motors, non-sparking motors and dust explosion-proof motors.

(2) Ordinary motor:

① According to the type of working power supply: it can be divided into DC motor and AC motor.

② It can be divided according to structure and working principle: it can be divided into DC motor, asynchronous motor and synchronous motor.

③ It can be divided according to the starting and running modes: capacitor-started single-phase asynchronous motor, capacitor-operated single-phase asynchronous motor, capacitor-started single-phase asynchronous motor and split-phase single-phase asynchronous motor.

④ Can be divided according to use: driving motors and control motors.

⑤ According to the structure of the rotor, it can be divided into: cage induction motor (called squirrel cage asynchronous motor in the old standard) and wound rotor induction motor (called wound asynchronous motor in the old standard).

⑥ It can be divided according to the operating speed: high-speed motor, low-speed motor, constant-speed motor, and speed-adjustable motor. Low-speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors and claw pole synchronous motors.
