Explosion-Proof Motor 11kW 15Hp

The Explosion-Proof Motor 11kW 15Hp converts electrical energy into mechanical energy, allowing the motor to operate at full capacity. This product is an optimal solution widely used in large and small industrial sectors due to its high level of safety. Let’s explore this explosion-proof motor with Thanh Thai Motor!

Overview Design of the 11kW 15Hp Explosion-Proof Motor

As an explosion-proof motor product belonging to the category of explosion-proof motors above 3.7kW, it features a thick cast iron outer casing designed to ensure the internal parts remain safe and withstand impact factors.

Inside the electric motor, larger copper windings are equipped compared to conventional motors, providing better heat resistance and stable operation in high-temperature environments.

Additionally, the explosion-proof motor is specially designed to prevent the risk of fire and explosion in the event of an electrical short circuit, meeting strict safety standards in hazardous environments such as mines, chemical plants, petroleum warehouses, etc.

Internal Structure of the 11kW 15Hp Explosion-Proof Motor

To maintain continuous operating performance at 11kW and ensure absolute safety in chemical or gas environments, all internal components of the motor must meet explosion-proof certifications.

• Stator: The stationary magnetic field core is pressed from low-loss electrical steel sheets. The pure copper winding is coated with a thick insulation layer and impregnated with multi-layer Class F vacuum varnish to withstand high temperatures and completely prevent electrical discharge.
• Rotor: The robust solid-cast squirrel-cage rotating core features an extremely smooth surface finish and computer dynamic balancing to completely eliminate mechanical friction that causes sparks inside the motor chamber.
• Bearings: Assembled with heavy-duty bearings from world-leading brands. The bearing system is integrated with multi-layer oil seals and non-flammable lubricating grease to prevent dust and gas from entering the shaft.
• Cooling system: The centrifugal cooling fan blades must be made of anti-static plastic or specialized aluminum alloy material to avoid generating static sparks when rubbing against the air.

• Drive coupling: It is mandatory to use hydraulic couplings or explosion-proof standard steel disc couplings for smooth starting, eliminating mechanical shock loads, and preventing friction-induced sparks.

Guide on How to Wire the Explosion-Proof Motor

To ensure the practical process is safe and accurate, follow the 5-step procedure directly below:

Step 1: Read equipment specifications

Before operating, you should watch the electric motor video to clearly understand the structure and technical indices of the motor. Understanding the equipment helps you choose the most correct wiring method.

Step 2: Open the terminal box cover

Use mechanical tools to remove the fixing bolts and take out the wiring box cover. The identification sign of this machine line’s terminal box is the letter “EX” printed on the cover.

Step 3: Locate the terminal studs

Observe the inside of the just-opened terminal box. You need to find and accurately identify the 3 copper contact studs marked with U, V, and W.

Step 4: Connect the power cable

Connect the 3 power wires respectively to the 3 newly found U, V, and W studs. Note that you must tighten the connection ends securely to avoid looseness causing electrical sparking during operation.

Step 5: Completion

Thus, you have completed the basic electrical wiring. To refer to more wiring diagrams for other machine lines, you can search for and watch technical summary videos on the Thanh Thai Motor channel.
