Abstract
An electric generator is provided including a rotor having a surface with permanent magnets disposed thereon. A stator is provided having an electrical winding wound thereon in grooves in the stator. An air gap is disposed between the stator and rotor. The electrical winding of the stator is connected to a variable inductance. The value of the variable inductance is controlled by a control stage. The output of the variable inductance is connected to a rectifier which feeds direct electrical current to a current accumulator device, for example, a storage battery. The variable inductance is controlled by the control circuit such that the electrical current from the electric generator is maintained substantially constant for a particular load by the adjustment of the inductance of the variable inductance.
