Inverters include energy-saving technology for no extra cost

Optimum efficiency for standard AC asynchronous motors is achieved around full load, and the efficiency falls steeply at partial loads; however, Lenze says that for machinery with substantial load variations, reduced running costs can be achieved by using the company's 8400 series frequency inverters.

Control for permanent magnet motors

For decades, induction motors have been the first choice for the majority of commercial and industrial applications. Now, however, attention is starting to shift to permanent magnet synchronous motors. But what are the benefits of using these, and how easy are they to control? Stephen Takhar of Vacon UK has the answers.
