The quest for energy efficient electric motors has generated a lot of interesting ideas. One of the latest is said to push the efficiency of induction motors to better than super-premium levels by ...

A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...

Geothermal power offers a stable, continuous source of renewable energy that could help power millions of homes while reducing dependence on fossil fuels. As governments worldwide pursue ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...

Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...
