Permanent Magnet Switched-Flux Machine

Description:

 

 

Background

With the ever-growing issues of energy security and climate change, there is increased interest in the use of renewable sources of energy which can be obtained using solar, geothermal, or wind-turbine technology. Although significant research has been made into each of those areas, prior art designs have typically not yielded the compact, economical, and efficient generators needed for, among other things, renewable energy sources (e.g., wind turbines).

 

Description

Researchers at the University of Nevada, Reno have developed a permanent-magnet switched-flux (PMSF) device where a single-phase PMSF device can operate as alternating current (AC) generators, while multi-phase PMSF devices can operate as either an AC generator or an AC motor.  This technology can be applied to synchronous machines which are commonly used as generators for large power systems such as turbine generators and hydroelectric generators.

 

Advantages

  • Our technology improves generation of voltage and torque in AC electrical devices.
  • Our device can provide or utilize low rotational speed of a rotor while still providing or utilizing relatively high-frequency alternating current.
  • Our PMSF device can be manufactured and maintained relatively easy, with relatively few components.
  • Our technology can be economical to both manufacture and use.
