Explosion-proof Motor 15kW 20Hp

With the Explosion-Proof Motor 15kW 20Hp, electrical energy is efficiently converted into mechanical energy, helping machinery operate powerfully and stably. Thanks to integrating superior safety features, this type of electric motor is widely used in many industrial and residential fields. Let’s explore this product in detail with Thanh Thai Motor!

General design of the Explosion-Proof Motor 15kW 20Hp

This explosion-proof motor is an explosion-proof motor above 3.7kW, specifically designed for flammable and explosive environments. The outer shell is cast from thick, sturdy iron, capable of withstanding strong impacts and safely protecting internal components.

The internal wiring has a larger cross-section than standard motors, helping it withstand high currents and harsh temperatures. The modern design meets explosion-proof standards, helping the motor operate stably in areas such as mines, petroleum warehouses, chemical plants, etc.

Internal structure of the Explosion-Proof Motor 15kW 20Hp

To maintain continuous operating performance at 15kW and ensure absolute safety in chemical or gas environments, all internal parts of the motor must achieve explosion-proof certification.

• Stator: Static magnetic field block pressed from technical steel sheets with low magnetic loss. Pure copper windings are coated with a thick insulation layer, impregnated with multi-layer Class F vacuum varnish to withstand high temperatures and absolutely prevent electrical discharge phenomena.
• Rotor: Sturdy solid-cast squirrel-cage rotating core, extremely smoothly processed surface and computerized dynamic balancing to completely eliminate mechanical friction generating sparks inside the machine chamber.
• Bearings: Assembled with heavy-duty bearings from top global brands. The bearing system is integrated with multi-layer seals and uses non-flammable lubricating grease to prevent dirt and gas from entering the shaft core.
• Cooling system: The centrifugal cooling fan blades must be made of anti-static plastic or specialized aluminum alloy material so as not to generate static sparks when frictioning with the air.

• Worm gear hollow-shaft gearbox: Can be coupled with vertical worm gearboxes codes WPA, WPS size 135 or 155 used in lifting mechanisms or mixing tanks.
• Drive coupling: It is mandatory to use explosion-proof standard hydraulic couplings or steel disc couplings to start smoothly, eliminate mechanical shock loads and prevent friction-induced sparks.

Instructions on how to wire the explosion-proof motor

To make the wiring process safe and accurate, you can follow these 5 basic steps:

Step 1: Understand equipment parameters

Follow the beginning of the electric motor video to record and understand the technical specifications of the machine before performing operations.

Step 2: Open the terminal box cover

Use specialized screw-opening tools to remove the bolts. Lift the terminal box protective cover (recognized by the red “EX” letter printed on the cover) out.

Step 3: Identify the positions of the copper terminals

Observe inside the newly opened terminal box. You need to find and accurately distinguish 3 contact terminals marked with symbols U, V, and W.

Step 4: Proceed to supply power

Take 3 cables from the power source (recognizable by red, yellow, blue wire clips) and connect them directly to the corresponding 3 terminals U, V, W.

Step 5: Complete the operation

Here you have completed basic wiring. If you want to learn the wiring diagram for more complex machine lines, you can search for and watch summary videos of technical instructions provided by Thanh Thai Motor.
