Combining motors and drives

Combining motors and drives Of the approximately 10 million motors installed in UK industry, only some 3 percent are controlled by variable speed drives. Despite the huge energy savings to be gained, often in excess of 50 percent, many companies are still not making use of variable speed drives to run their motors. Yet, process operators cannot simply connect a drive to any old motor and expect huge energy savings overnight or even a successful motor and drive match. To minimise the risk that the selected motor will fail, users need to understand the required operating and environmental characteristics of the application. Motors have to cope with all sorts of environments, from high ambient temperatures, to being immersed in sewage, to operating in dust or gas hazards. Special designs exist for all of these cases and the user must ensure he follows the motor manufacturer's instructions. Getting all the help you can from motor and drive manufacturers is also a good idea in general; their experience with motors and drives will help find the most compatible motor and drive combination. Many will have local service representatives that can help set up the drive. Users installing their own drives need to read up about the issues that exist when connecting AC motors and drives.
