The use of inverter-based variable speed drives (VSD) in home appliances is forecast to double over the next five years according to IMS Research.

Currently, said IMS, appliances with VSD account for just one in eight new appliances - mainly room air-conditioners and washing machines. However, times are changing quickly, said an IMS report on the subject.

"While home appliance shipments have decreased globally, the use of electronics within them has not," commented report author Jason dePreaux. "One of the main drivers of this trend has been the global emphasis on energy efficiency. A large number of countries continue to amend minimum performance standards and comparative labeling schemes in an effort to curb electricity consumption," added dePreaux. "For example, the EU is currently revamping its label of refrigerators despite the fact that it was updated a mere four years ago. The swiftness of appliance efficiency rulemaking means that future appliances must be smarter in the way they use power."

In addition to increased efficiency, the report said that variable speed motor control also appeals to appliance makers’ desire for more reliable performance and quieter operation. Shipment growth of appliances with variable speed motor drives is forecast to grow rapidly over the next five years.
