Selecting the Right Motor Drive Platform for Variable Speed Drive Systems

Posted by Dave Zendzian on Jun 4, 2013 12:32:00 PM

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.

Wireless Electric Vehicle Charging at CES 2011

This week Las Vegas is hosting the 2011 International Consumer Electronics Show, a trade show where hundreds of consumer oriented companies annouce their new products. While I'm not there, I am paying close attention to all of the news coverage.

One interesting product that has popped up is from Fulton Innovation's eCoupled product line. Their demo in Las Vegas includes wirelessly charging a Tesla Roadster. I believe that wireless charging of Electric Vehicles will greatly increase their adoption in the US. If I can pull into my garage every day, and let the car charge on its own, I'd be much more likely to make the switch to Electric Vehicles. Nothing to plug in - just park and walk away.
