As commercial and industrial machinery has become more powerful and energy-efficient, the use of variable speed drives (VSD) has become more popular for a wide range of applications. You’ll now find VSD systems in everything from heavy industrial equipment to high speed commercial systems such as conveyors, fans, pumps, and blowers.
What many OEMs like about VSDs is their ability to save energy while providing more flexible control – in fact, with the rising cost of energy, many companies choose VSDs just for energy efficiency alone. Choosing the right motor drive is critical, though, to ensure cost-efficiency. While cost is a major consideration for choosing a motor drive, there are other factors, too, including harmonics, cabling and cooling costs, especially for high power systems.
