Explosion Proof Motor Classifications
The types of explosion-proof electric motors can be classified according to the
following aspects:

1. Principle of motor

Explosion flame proof motor can be divided into explosion-proof asynchronous
motor, explosion-proof synchronous motor and explosion-proof DC motor.

2. Place of use

Explosion proof VFD motorcan be divided into explosion-proof motors used in
coal mines and explosion-proof motors used in factories.

3. Explosion-proof principle

Explosion proof VFD motor can be divided into flameproof motor, increased
safety motor, positive pressure motor, spark-free motor and dust explosion-
proof motor.

4. Matching mainframe

Explosion proof VFD motor can be divided into explosion-proof motor for coal
mine conveyor, explosion-proof motor for coal mine winch, explosion-proof motor
for scraper, explosion-proof motor for local fan in coal mine, explosion-proof
motor for fan, etc. In addition, it can also be divided according to technical
indicators such as rated voltage and efficiency, such as high-voltage
explosion-proof motor and low-voltage explosion-proof motor.

How to choose An Electric Explosion Proof Motor?
Selection principle of explosion-proof electric motor

1. Identify the nature and types of application places.

2. For gas explosive places, zoning should be determined according to the
degree of danger.

3. Identify the temperature group of the application place.

4. For flameproof, safety-increasing and positive pressure ventilation
explosion-proof motors, the use places should be considered are class or class;
Spark-free motor and dust explosion-proof motor can only be used in similar
places.

5. Identify the explosion-proof level.

6. If safety-increasing or positive pressure explosion-proof motors are
selected, corresponding protection devices should be considered, otherwise the
safety of explosion-proof cannot be guaranteed.

Application of the Explosion Proof VFD
The frequency converter application is very extensive, and explosion proof DC
motor also has its own unique uses.

The explosion proof VFD is mainly used for heavy load starting and full speed
regulation of scraper conveyor, transfer machine, belt conveyor, coal mine TBM
and other equipment with rated voltage of 3300v / AC1140v / AC660V, and can be
used for the emulsion pump station, water pump, endless rope winch, permanent
magnet synchronous motor (including electric drum), ventilator and other
occasions requiring frequency conversion speed regulation.
