Explosion-proof Motor 45kW 60Hp

The Explosion-Proof Motor 45kW 60Hp converts electrical energy into mechanical energy, ensuring energy efficiency and explosion safety. This electric motor has been highly rated among explosion-proof series for many years. Let’s explore this product with Thanh Thái Motor!

General design of the Explosion-Proof Motor 45kW 60Hp

This explosion-proof motor features a special design with a characteristic gray/blue paint finish, providing clear identification. The motor housing is made of rigid cast iron, offering strong impact resistance and high durability in harsh working environments. The cast iron material also helps the motor resist corrosion, rust, and the effects of hazardous chemicals.

In particular, the Explosion-Proof Motor 45kW 60Hp is evaluated as superior to other explosion-proof motor lines in the same segment above 3.7kW due to its effective explosion-proof capability. This motor is specially designed to ensure safety in the event of an electrical failure, minimizing risks and enhancing reliability during operation.

Internal structure of the Explosion-Proof Motor 45kW 60Hp

To maintain continuous operation performance at 45kW and ensure absolute safety in chemical and gas environments, all internal components of the motor must meet explosion-proof certification (Ex d):

• Stator: Static magnetic field core pressed from low core-loss electrical steel sheets. Pure copper windings coated with thick insulation, multi-layer vacuum varnish impregnation (Class F or Class H) to withstand high temperatures and completely prevent electrical discharge phenomena.
• Rotor: Sturdy cast squirrel-cage rotor core, with extremely smooth surface machining and computer dynamic balancing to completely eliminate mechanical friction causing sparks inside the motor chamber.
• Bearings: Assembled using heavy-duty bearings from top global brands (SKF, NSK, FAG). The bearing system is integrated with multi-layer seals and non-flammable lubricating grease to prevent dust and gas from entering the shaft core.
• Cooling system: The forced centrifugal cooling fan must be made of anti-static plastic or specialized aluminum alloy material to avoid generating static sparks when rubbing against the air.
