An inductor alternator is adapted to generate high-frequency ac power. Inductor alternators have no electrical connection or permanent magnets on the rotor. The alternator is provided with a stator having a circular array of major teeth, each major tooth being slotted to define several minor teeth. Surrounding each major tooth in the array is an armature coil. The array is divided into sets each having a like number of major teeth. Surrounding each set of major teeth is an excitation winding to which an excitation voltage is applied to establish lines of magnetic flux passing through the minor teeth. Associated with the stator is a rotor having a circular series of small rotor teeth that project to face the minor teeth on the stator. When the rotor is driven, the rotor teeth then travel past the minor teeth on the stator to intercept the lines of magnetic flux, thereby inducing in the armature winding a high-frequency voltage.
