Explosion Proof Variable Frequency Drives 1140V 75kW / 660V 110kW


The explosion proof VFD is committed to intelligent control of mining. Our
explosion proof electric motor can improve the efficiency of the equipment, and
reduce the maintenance of the complete set of equipment. The explosion proof
electric motor operates reliably to ensure production safety. Our ATEX and IEC
explosion-proof motor has advanced design concepts and independent intellectual
property rights, and have reached the international advanced level in terms of
functionality and reliability.

Features of the Explosion Proof VFD
The software system of explosion proof panel box has built-in control programs
such as a scraper, conveyor, and pumping station;

Direct torque control has high control precision, fast dynamic response speed,
and output torque greater than 2.2 times rated torque, which is suitable for
heavy load starting occasions.

Explosion proof VFD adopts CAN bus communication to realize master-slave
control and power balance of multiple devices, and optical fiber communication
is supported to realize data transmission and control;

ATEX explosion proof VFD uses Long-life thin-film capacitors;
This electrical transmission equipment has various protection functions such as
overload, overvoltage, under-voltage, phase shortage, overheating, power
imbalance, short circuit, etc.

Our ATEX explosion proof VFD is equipped with high quality explosion proof
electrical panels, connectors, enclosures, junction boxes, outlets and other
explosion proof electrical boxes and fittings.

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.
