Explosion-proof Motor 22kW 30Hp

The Explosion-Proof Motor 22kW 30Hp efficiently converts electrical energy into mechanical energy, helping machinery operate at maximum performance in environments with a high risk of explosion. This is a reliable solution widely used in industry thanks to its superior safety and high durability. Thành Thái Motor is a reputable distributor specializing in quality explosion-proof motors that operate stably and safely for customers.

General Design of the Explosion-Proof Motor 22kW 30Hp

The overall design of explosion-proof motor products above 3.7kW, specifically the Explosion-Proof Motor 22kW 30Hp, features a thick, sturdy cast-iron outer casing capable of withstanding heavy loads and protecting internal components from severe impacts. The internal wiring has a large cross-sectional area and high heat resistance, helping the electric motor operate reliably in harsh environments.

In particular, in the event of electrical faults such as short circuits, the motor ensures no sparks or explosions are generated, strictly meeting stringent safety standards in flammable environments such as mines, chemical warehouses, or areas containing easily combustible gases.

Internal Structure of the Explosion-Proof Motor 22kW 30Hp

To maintain continuous operating performance at 22kW and ensure absolute safety in chemical and gas environments, all internal parts of the motor must achieve explosion-proof certification (Ex d):

• Stator: The stationary magnetic field block is pressed from technical steel sheets with low core loss. Pure copper windings are coated with thick insulation, and multi-layer vacuum varnish impregnated (Class F or Class H) to withstand high temperatures and absolutely prevent electrical discharge phenomena.
• Rotor: The solid, one-piece cast squirrel-cage rotating core features an extremely smooth surface finish and computerized dynamic balancing to completely eliminate mechanical friction that causes spark generation inside the machine chamber.
• Bearing (Ball bearing): Assembled with heavy-duty bearings from world-leading brands (SKF, NSK, FAG). The bearing system integrates multi-layer oil seals and non-flammable lubricating grease to prevent dust and gases from entering the shaft.
• Cooling system: The centrifugal cooling fan must be made of anti-static plastic or specialized aluminum alloy material to prevent static spark generation when rubbing against the air.

What Gearbox Can the Explosion-Proof Motor 22kW 30Hp Be Combined With?

Pairing the 22kW explosion-proof motor with drive equipment requires extremely strict safety factor calculations to ensure the gearbox does not break under the pulling force of the 30Hp motor.

• Heavy-duty gearbox (R, K, F Series): This is the standard option. Large gearbox codes such as R87, R97 or K87, K97 fully immersed in oil are typically used to drive mine conveyor systems.
• Hollow shaft / worm gearbox: Can be paired with vertical worm gearboxes (such as WPA, WPS size 135 or 155) used in lifting mechanisms or mixing tanks.
• Drive coupling: It is mandatory to use a hydraulic coupling or ATEX explosion-proof standard steel disc coupling for smooth starting, eliminating mechanical shock loads, and preventing spark generation due to friction.

How to Wire an Explosion-Proof Motor

Below are practical, concise, and safe operational steps for you to easily follow:

Step 1: Read equipment specifications

Before getting started, carefully watch the beginning of the electric motor video to understand the motor’s technical specifications.

Step 2: Open the terminal box cover

Use mechanical tools to loosen the bolts and remove the protective cover (printed with a red “EX” letter) from the machine.

Step 3: Identify wiring positions

The copper terminals will be exposed inside the terminal box. You need to look closely and find the 3 terminals marked U, V, and W.

Step 4: Connect the power source

Take the 3 phase wires from the power source (red, yellow, and blue clamps can be used for easy identification) and connect them directly to the 3 terminals U, V, and W just located.

Step 5: Completion

You have completed the basic wiring process. If you need to learn more complex wiring diagrams or other machine lines, please refer to the technical compilation videos on the Thành Thái Motor channel.
