How to Select a Speed Drive

When you attach a speed drive to a fan or pump, and power it from an electric motor, the drive can reduce your energy consumption up to 50 percent. It does this by lowering motor speeds. A speed drive controls motor speed, while running it on a setting less than full speed. The price of speed drives is going down (as of April 2011), but even with lower costs these drives remain unpopular. Buying and installing a speed drive requires thorough consideration and selection.

Instructions

- 1
  Consider whether you require fans or pumps that do not require a full running speed. If you have motor-driven equipment that can run on variable speed, without affecting the process much, then full speed is not required.
- 2
  Select a reputable supplier. A proper supplier will advise you as to what speed drive is most essential for your business.
- 3
  Check the local entries for speed drives in your area. Obtain the contact information and details of nearby authorized suppliers or manufacturers.
- 4
  Shop around and take quotes from various suppliers to get the best bargain.
- 5
  Contact authorized installers for the installation of a speed drive after making a selection. This will ensure your drive is installed correctly and swiftly.
