Main differences between explosion-proof motors and ordinary motors

1. Different meanings:

(1) Explosion-proof motor is a kind of motor that can be used in inflammable and explosive places, and it does not produce electric spark when running.

(2) Electric machine (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that converts or transmits electric 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 widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other sectors. As the main power equipment, explosion-proof motor is usually used to drive pumps, fans, compressors and other transmission machinery.

(2) Ordinary motors can no longer be used in flammable and explosive situations.

3. Different classifications:

(1) explosion-proof motor:

① According to the principle of 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 motor for coal mine and explosion-proof motor for factory.

③ According to explosion-proof principle:

It can be divided into flameproof motor, safety-increasing motor, positive pressure motor, spark-free 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 operating modes, it can be divided into 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 It can be divided into driving motor and control motor according to their uses.

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

⑥ According to the running speed, it can be divided into high-speed motor, low-speed motor, constant-speed motor and speed-regulating motor. Low-speed motors are divided into gear deceleration motors, electromagnetic deceleration motors, torque motors and claw-pole synchronous motors.
