Permanent Magnet Generator with Mechanical Controller

The power generating efficiency of conventional automotive generators is about 50%. To install vehicles with larger high-power generators that are able to satisfy electrical demand would be difficult. This research project created a generator that uses a permanent magnet (PM) for the rotor and incorporates a new mechanical controller that obtains a generating efficiency of 90% and is capable of maintaining a constant voltage. An air-gap controller between the rotor and the stator was adapted to control the magnetic force in order to adjust the voltage to changes in speed and load.
