Using hazardous area motors with drives

If you use hazardous area motors with drives, there are a few things you need to think about: but with a motor and drive from ABB, they have already worked out the details for you

If you use hazardous area motors with drives, there are a few things you need to think about.

However, if you get the motor and the drive from ABB, there is no need for further action - we have already worked out the details for you.

ABB has blanket certification for motor and drive combinations for hazardous areas.

This means that no further testing is required once on site.

But if you match your own drive and motor combination, it may need to be independently tested by a notified body.

Variable speed operation gives higher temperature rise and higher voltage stress on the motor insulation, in combination with reduced cooling in self-cooled motors.

These factors combined could create a heat source powerful enough to ignite an explosion.

At ABB, we have designed our motors for use with variable speed drives for the last 30 years.

We have the experience to guarantee safe operation in hazardous areas - and we have the certificates to prove it.
