Explosion-Proof Motor 7.5kW 10Hp

The Explosion-Proof Motor 7.5kW 10Hp is a perfect solution for converting electrical energy into mechanical energy, helping the motor operate at full load and safely in explosive environments. This is an essential product in the industry, especially in areas requiring high safety and harsh working environments. Let’s learn about this product with Thanh Thai Motor!

General design of the Explosion-Proof Motor 7.5kW 10Hp

This explosion-proof motor is a product in the explosion-proof motor segment above 3.7kW, machined with a thick cast iron housing, good load-bearing and impact resistance, providing comprehensive protection for internal components.

The internal conductors are designed larger than smaller capacity lines, helping to increase heat resistance, suitable for high-temperature production environments.

In addition, this electric motor line also has a specialized structure to prevent explosions caused by electrical sparks or short-circuit incidents, ensuring maximum safety for the system and personnel during operation.

Internal structure of the Explosion-Proof Motor 7.5kW 10Hp

To maintain continuous operating performance at 7.5kW and ensure absolute safety in chemical or gas environments, the internal parts of the motor must all 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, multi-layer vacuum varnish impregnated to Class F standards to withstand high temperatures and absolutely prevent electrical discharge.
• Rotor: Sturdy solid-cast squirrel cage rotating core, with an extremely smooth surface machining and computer dynamic balancing to completely eliminate mechanical friction causing sparks inside the machine chamber.
• Bearings: Assembled with heavy-duty bearings from world-leading brands. The bearing system is integrated with multi-layer seals and uses non-flammable lubricating grease to prevent dust and gas from entering the shaft.
• Cooling system: The centrifugal cooling fan blade must be made of anti-static plastic or specialized aluminum alloy material to avoid generating static sparks when rubbing against the air.

Which gearbox does the 7.5kW 10Hp explosion-proof motor combine with?

Pairing the 7.5kW explosion-proof motor with drive equipment requires extremely strict safety factor calculations to ensure the gearbox is not broken under the pulling force of the 10Hp motor.

• Heavy-duty helical gearbox: This is a standard option. Large gearbox codes such as R67, R77 or K67, K77 fully immersed in oil are usually used to drive mining conveyor systems.
• Hollow shaft worm gearbox: Can be paired with vertical worm gearboxes codes WPA, WPS size 120 or 135 used in large capacity mixing tanks.
• Drive coupling: It is mandatory to use explosion-proof standard hydraulic couplings or steel disc couplings for smooth startup, eliminating mechanical load shock and preventing spark generation due to friction.

Instructions for wiring a 3-phase electric motor

Before proceeding with wiring, you should refer to electric motor videos to clearly understand the structure as well as the position of the terminal posts, helping operation to be more accurate and safer.

Step 1: Remove the terminal box cover of the electric motor

Use a suitable screwdriver to remove the 4 fixing bolts on the terminal box cover. When opening the cover, the system of wiring terminals will be exposed inside. For common 3-phase motors, this area usually has 6 wire ends clearly labeled.

Step 2: Identify the terminal posts and 380V power supply

The wire ends in the terminal box are arranged in two rows. The lower row, labeled U1, V1, W1, is the position used to connect the input power source for the motor.

Step 3: Connect 3-phase power to U1, V1, W1

Prepare 3 phase wires from the 380V power supply and proceed to connect them respectively to the U1, V1, W1 posts. It is necessary to ensure correct positioning for the motor to operate stably.

Important safety note:

Terminal lugs must be tightened to ensure good electrical contact, limiting electrical sparks causing short circuits and fires. Absolutely do not connect power to the upper terminal row (U2, V2, W2) as this may damage the motor windings.

Step 4: Close the cover and test run

After completing the connection, tightly close the terminal box cover and tighten the bolts to protect the equipment from dust and moisture. Power on to check operation. If the motor rotates in the reverse direction of desire, simply disconnect the power and swap the positions of two of the three phase wires to reverse the rotation direction.

Following the correct procedure not only helps the system operate stably but also ensures long-term safety. Electric motor videos from Thanh Thai Motor will be a useful reference source for users in practice.
