1. Different meanings:

(1) Explosion proof motor is a type of motor that can be used in flammable and explosive places without generating sparks during operation.

(2) Electric motor (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 widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine, etc. Explosion proof motors, as the main power equipment, are usually used to drive pumps, fans, compressors, and other transmission machinery.

(2) Ordinary motors should not be used in flammable and explosive environments.

3. Different classifications:

(1) Explosion proof motor:

a. According to the principle of electric motors:

It can be divided into explosion-proof asynchronous motors, explosion-proof synchronous motors, and explosion-proof DC motors, etc.

b. Classified by place of use:

It can be divided into explosion-proof motors used underground in coal mines and explosion-proof motors used in factories.

c. According to the principle of explosion prevention:

It can be divided into explosion-proof motors, increased safety motors, positive pressure motors, spark free motors, and dust explosion-proof motors.

(2) Ordinary motors:

a. According to the type of working power supply, it can be divided into DC motors and AC motors.

b. According to structure and working principle, it can be divided into DC motors, asynchronous motors, and synchronous motors.

c. According to the starting and operating modes, 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.

d. According to their uses, they can be divided into drive motors and control motors.

e. According to the structure of the rotor, it can be divided into cage induction motors (formerly known as squirrel cage asynchronous motors) and wound rotor induction motors (formerly known as wound asynchronous motors).

f. According to the operating speed, it can be divided into: high-speed motor, low-speed motor, constant speed motor, and variable speed motor. Low speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors, and claw pole synchronous motors.
