Explosion-proof Motor 1.1kW 1.5Hp

The Explosion-proof Motor 1.1kW 1.5Hp plays the role of converting electrical energy into mechanical energy, with high safety assurance in environments requiring explosion protection. Widely applied in many industries, this motor is a reliable choice. Let’s explore more about the explosion-proof motor product (explosion-proof motor / explosion-proof motor) in the article below!

Overview design of the Explosion-proof Motor 1.1kW 1.5HP

The Explosion-proof Motor 1.1kW 1.5Hp belongs to the product group of explosion-proof motors under 3.7kW, featuring an improved design with a thick, durable cast iron housing that protects the motor from environmental impacts and provides good impact resistance.

The internal wiring material of the electric motor is optimized with a large size, helping to increase high-temperature resistance.

In particular, the Explosion-proof Motor 1.1kW 1.5Hp has effective explosion-proof capabilities, ensuring safety in the event of electrical short circuits, bringing reliability in high-safety industrial applications.

Internal structure of the Explosion-proof Motor 1.1kW 1.5Hp

Every operating detail inside the equipment must pass a series of explosion-safety tests before leaving the factory to eliminate all potential risks.

• Stator: Stationary magnetic field block shaped from technical steel sheets to eliminate electrical energy losses. The tightly wound copper coil inside features Class F heat-resistant insulation, maintaining absolute safety when the device operates continuously for many hours.
• Rotor: Squirrel-cage rotating block made from solid steel alloy. This component is intricately computer-finetuned for dynamic balancing to eliminate physical friction phenomena generating electrical sparks during rapid rotation.
• Bearing: Industrial bearings accompanied by multi-layer dust-proof seal systems and specialized lubricating grease, helping to maintain smooth movement and preventing excessive heat generation for the shaft.
• Cooling system: The fan assembly mounted at the shaft end uses non-electrostatic synthetic plastic material, thereby completely eliminating the risk of electrostatic discharge when the blades cut through the airflow.

• Drive coupling: Use plum flexible couplings or hydraulic couplings to minimize the risk of ignition caused by metal friction.

Wiring guide for explosion-proof motors

Follow these 5 steps for safe and standard wiring:

Step 1: Cut off power and inspect parameters

Completely cut off the mains power. Read the label on the machine housing and refer to the electric motor video beforehand to understand the rated voltage, thereby choosing the appropriate cable type.

Step 2: Open the terminal box cover

Use tools to loosen the screws and take out the cover with the “EX” mark. Handle with care, absolutely avoiding tearing the rubber gasket edge at the box rim.

Step 3: Locate the copper terminals

Look inside the box, correctly locate the 3 terminals U, V, W. Check whether the copper strips are connected in delta or star configuration to see if they match the supplied power grid.

Step 4: Secure wires and ground connection

Crimp the cable lugs and connect them to the U, V, W terminals. It is mandatory to tighten the nuts firmly to prevent the risk of sparking. Next, connect an additional grounding cable to the specified terminal.

Step 5: Seal the protective cover tightly

Reinstall the cover, press it tightly against the rubber gasket edge, and tighten the bolts evenly at all corners. If you need to learn about the circuit diagrams of other equipment lines, check out the compilation videos on the Thanh Thai Motor channel.
