4. How To Maintain Explosion Proof three phase Motors?

The design of an explosion-proof motor ensures sufficient durability and functionality. Despite this, it requires proper maintenance to keep it fully operative for a long time. You should consider the following maintenance options for this motor.

Predictive Maintenance

This maintenance deals with instant fault detection and solving. Different testing methods like vibration tests, thermal imaging tests, etc are reliable to find the defect at the right time.

You need to conduct these tests to predict the problem from time to time. Thus, you can significantly reduce labor and repair costs. Predictive maintenance takes care of motor problems and saves them from complete falling.

Figure 4- Explosion Proof Motor Maintenance

Preventive Maintenance

You need to apply some preventive measures to develop its maintenance. Such as:

  • Regularly conduct the motor winding test.
  • Inspect the motors visually to identify the burn signs. Besides, you can get a smell of burning due to overheating sometimes.
  • Keep the component’s joints tight.
  • Check the fuses and starter switches.
  • Keep the motor away from extreme noise and vibrations.
  • Use grease in bearings. It improves lubrication to a great extent.

Preventive maintenance prevents irregular shutdown of explosion proof motors and develops performance. You have to maintain this over a certain period based on the guideline of the manufacturer.

Besides, you have opportunities to apply reactive maintenance when the motor breaks. That means this process deals with replacing. It is required for you to make a balance among these options. Then, you can optimize the use of an explosion-proof motor.

5. What Is The Difference Between Explosion Proof Motors And Other Types Of Motor Enclosures?

Explosion-proof motor improves the use of electronic appliances in hazardous environments. It provides better performance than other types of motor enclosures because of its useful mechanism and materials.

Here, we are going to explore some considerable points that make this induction electric motor different from others.


Explosion proof motors are applicable in both indoors and outdoors with great durability. But, other motors, like ODF (Open Drip Proof) motors are used only indoors and in regular atmospheres. These motors have only open enclosures.

Figure 5- Explosion Proof Motor Applications

Figure 5- Explosion Proof Motor Applications


The maintenance of the enclosure used in an explosion proof electric motor is easier than conventional motors. Such as, washdown enclosures require regular maintenance to achieve optimum performance that is a time-consuming process.

Cooling Mechanism

Explosion proof motors have integrated cooling systems that ensure adaptability with high temperatures. In contrast to these motors, totally enclosed fan-cooled induction motors contain an external fan. Thus, TEFC motors can transfer air outside the motor. But, this is not as impressive as explosion proof three-phase induction motors.

Resistance To External Contaminants

Effective design and using robust materials turn the explosion proof motor’s enclosure resistant to external contaminants. That’s why air, moisture, liquid, etc can’t cause any adverse effects in its functioning. You also get an idea about its resistance from the IP rating (IP55).

On the contrary, a totally enclosed non-vented (TENV) induction electric motor enclosure is not reliable against a certain flow to water or dust.

Stress Management

Explosion proof induction motor shows outstanding performance in handling mechanical stresses. Its IK rating indicates the effectiveness of this motor in stress management. But, traditional induction motors don’t provide such robustness in dangerous environments.

6. How To Extend The Lifespan Of Explosion Proof Motors?

Explosion proof motors have a long lifespan that is significant in typical industrial sectors. You can keep these motors operative for more than their average lifespan if you maintain some instructions.

The following measures will help you to ensure smooth operation and prevent the sudden failure of an explosion proof induction electric motor.

Reliable Cooling System

Maintaining proper cooling is mandatory for running an explosion proof motor continuously. That’s why you should make sure that the existing cooling mechanism can transfer air outside the induction motor properly. Otherwise, you need to consult with your manufacturer to solve this issue.


Proper use of lubricants in explosion proof motors reduces friction and heat. Lubrication improves the dynamics of components to a certain extent. You need to make sure that the lubricant does not contain any debris and its viscosity level is perfect for the motor’s equipment.

Voltage Control

Excessive voltage supply and frequent changes in voltage are not supportive of the flawless functioning of electric motors. Especially, YBX3 series explosion proof electric motors require superlative voltage control. If not, these motors get hot and cause serious damage.

Proper Inspection

This is a vital part when you are trying to extend the lifespan of explosion proof motors. Trustworthy thermal and vibration tests are essential for the motor’s quality control. High vibrating pressures hamper the load distribution and component alignment.

So, you must check the mountings and make them tight to handle extreme stresses.

Proper Handling

You must follow the storage guideline provided by the manufacturer and properly handle the motors while using or storing. For example, explosion proof motors should be kept under 1000m altitude.

Most noteworthy, you need to provide sufficient heat while storing these motors. Usually, the ambient temperature should not exceed 40⁰C to achieve optimum reliability.
