AC Drives Manufacturer Links

" Adjustable speed drive (ASD) is one of the most general terms applied to equipment used to control the speed of machinery. Adjustable speed drives are also known as variable speed drives (VSD).

Industrial machinery is often driven by electric motors that have provisions for speed adjustment. Such motors are simply larger, more powerful versions of those driving familiar appliances such as food blenders or electric drills. These motors normally operate at a fixed speed. If speed control is required that controller is called an adjustable speed drive." Click here to learn more.
