YBX3 Flameproof Three-Phase Asynchronous Motor

The explosion-proof motors are among the best in the market as they meet the various standards laid out for an explosion-proof motor. Such include EX dl, Ex dllAT4, and EX dllBT4 standards. As such, these motors can work in different harsh conditions without exploding. The explosion-proof motors have a highly developed structure for handling different voltage ranges. The motors can handle voltages from 200V to 690V. As such, they will be ideal options for those who want motors for low, medium, and high voltage applications.

The explosion-proof motors have a highly developed structure for handling different voltage ranges.

The motors can handle voltages from 200V to 690V. As such, they will be ideal options for those who want motors for low, medium, and high voltage applications.

The explosion-proof motors are also available in different installation styles.

The most common include IM B3, IM B35, and IM V1. It is easy to see how versatile motors are to own today.

The use of die-cast iron material to make the motors improve their durability. Considering you would be using them in some harsh environments, any buyer wants a durable motor.

These motors are also impact-resistant and good at heat dissipation. For a motor to work effectively, it needs to work within its rated temperature. Since the motors are good at heat dissipation, you should no longer worry about them failing any time soon.

How can the Explosion Proof Motor be Used?

Some might be wondering, when do you need an explosion-proof motor?

Well, We recommend that you use them if you work in the following industries;

• Waste and wastewater industry
• Oil and gas industry
• Chemical industry
• Forest products industry
• Explosive atmosphere environment

Such explosion-proof motors would primarily be used to run pumps, conveyors, compressors, gear reducers, fans, and more.

What are the Common Maintenance Tips for Explosion Proof Motors?

Explosion-proof motors are designed with durability in mind.

Even if they are durable, they still need the best maintenance to keep them working correctly over the years.

The maintenance can be categorized into three major options. They include preventative motor maintenance, predictive motor maintenance, and reactive motor maintenance.

Preventive Explosion Proof  Motor Maintenance

For this type of maintenance, the user will help prevent the motor from failing prematurely and keep it operating reliably. It is a calendar-based type of maintenance. This is where a manufacturer tells you what you should do after a certain period.

You can achieve this maintenance by doing the following;

• Visually inspect the motor. Mainly looking for burn marks or burned odor from the motor overheating
• Check the bearings for signs of vibrations and noise
• Perform a motor winding test
• Always grease the bearings to provide better lubrication
• Look at the starter switch, fuses, and connections. Make sure they are all tightened properly
• Record the inspects, repairs, or replacements done on the motor for future reference
