Explosion-proof Motor 2.2kW 3Hp

The Explosion-proof Motor 2.2kW 3Hp helps convert electrical energy into mechanical energy, allowing the motor to operate at its maximum possible capacity. The safety of this electric motor is trusted and used across industrial sectors. Thanh Thai Motor will explore the explosion-proof motor product with customers in this article!

General design of the Explosion-proof Motor 2.2kW 3Hp

The Explosion-proof Motor 2.2kW 3Hp is a typical product belonging to the explosion-proof motor category under 3.7kW, optimally designed for harsh industrial environments.

The motor typically uses a thick and sturdy cast iron housing to protect the internal core, increase heat resistance, impact resistance, and ensure long-term durability.

With its special structure, the explosion-proof motor also uses larger copper windings to increase electrical conductivity efficiency while well meeting explosion safety requirements, especially in flammable or electrically hazardous environments.

Internal structure of the Explosion-proof Motor 2.2kW 3Hp

To ensure the equipment operates smoothly and without incidents in sensitive chemical environments, all core components of the machine undergo extremely strict explosion-proof testing.

• Stator: The stationary magnetic core is made of countless technical steel sheets pressed tightly together. The internal winding is made of pure copper, coated with Class F heat-resistant insulation to maintain stability when running continuously for hours.
• Rotor: The squirrel-cage rotating core combined with an ultra-hard wear-resistant steel shaft. The entire rotor assembly undergoes a strict dynamic balancing procedure to avoid dangerous vibrations or mechanical friction-induced sparks.
• Bearing: This part is selected from the world’s leading manufacturers, accompanied by multi-layer dust seals and explosion-proof lubricating grease to ensure maximum smoothness of the rotating shaft.
• Cooling system: The centrifugal fan at the rear of the machine uses antistatic plastic material, absolutely preventing the risk of charge accumulation when rubbing against the cooling airflow.

Which gearbox does the Explosion-proof Motor 2.2kW 3Hp combine with?

To transmit kinetic energy most effectively, the 2.2kW device needs to be paired with high safety factor gearboxes to prevent overloading from cracking gears.

• Helical gearbox: This method brings excellent mechanical durability. Users usually prioritize R37, R47 or K37, K47 codes immersed in specialized oil to drive conveyors.
• Worm gear reducer: This equipment is very suitable when assembled with WPA, WPS sizes 70 or 80 to serve basic lifting mechanisms in factories.
• Drive coupling: It is recommended to use flange couplings or explosion-proof hydraulic couplings to limit the risk of sparking caused by direct metal friction.

Wiring instructions for explosion-proof motor

Follow these 5 steps to ensure safety when performing wiring operations:

Step 1: Cut off power and check specifications

Turn off the main circuit breaker. Read the nameplate carefully and watch the electric motor video to determine the correct working voltage, thereby preparing the cable of appropriate size.

Step 2: Remove the terminal box cover

Use a wrench to loosen the bolts and remove the cover (printed with “EX”). Pay close attention to operate carefully so as not to damage or shift the rubber gasket at the edge of the box.

Step 3: Distinguish copper terminals

Observe inside to correctly identify the 3 connection terminals engraved with U, V, W. Check if the copper bars are wired in a star or delta circuit to match the current power grid.

Step 4: Connect cables and grounding

Crimp lugs for the wires and attach them directly to terminals U, V, W. A mandatory requirement is to tighten the screws tightly to prevent sparking. At the same time, do not forget to connect a wire to the grounding terminal.

Step 5: Close the box cover

Close the cover properly aligned with the rubber gasket and tighten the screws evenly. If you need wiring instructions for other equipment lines, look for compilation videos from Thanh Thai Motor to view more.
