An inner core 62 and a resolver rotor 63 are secured to a rotary shaft 68 so that they are coaxial. A spacer 2, is provided between the inner core 62 and the resolver rotor 63. The spacer 2 and the inner core 62 are formed as a unit with separation, or space, between the spacer 2 and flange 41 of the inner core 62. The thickness of flange 41 is greater than the corresponding width of the corresponding part of the outer core, on which a rotary transformer input winding is wound. The resolver rotor 63 is a separate unit from the spacer 2 and the inner core 62, which facilitates automatic winding of the rotor. Grooves 3, 42 are formed in the spacer 2 and the flange 41 to accommodate a crossover wire 60.

An AC unipolar generator provides high power at high frequencies without requiring a source of high-frequency mechanical power. A rotor having a plurality of spaced magnetic disks and two sets of rotating capacitor plates is coupled to a source of mechanical power, the two sets of rotating capacitor plates being spaced apart along the outside of the rotor and electrically connected via a conducting channel. A stator surrounding a portion of the rotor that includes the magnetic disks and one of the two sets of rotating capacitor plates includes a magnetic stator core that forms a magnetic circuit with the magnetic disks of the rotor, a stator field coil, and a fixed set of capacitor plates that capacitively couple the stator field coil to the rotor conducting channel through one of the sets of rotating capacitor plates. A second fixed set of capacitor plates located outside of the stator capacitively couples the rotor conducting channel back to the stator field coil through the other set of rotating capacitor plates. The stator field coil and the two sets of capacitor plates form a resonant LC circuit that characterizes the AC frequency of the power generated by the generator.

A method of operating an alternator of a motor vehicle includes the steps of monitoring an amount of stored electrical energy available to operate the vehicle, estimating a vehicle electrical load, and regulating an output of the alternator based at least in part on the amount of electrical energy available to the vehicle and the estimated vehicle electrical load.

A non-linear magnetic harmonic motion converter apparatus for transferring non-linear motion into rotational motion for producing work from an interaction of at least two magnetic fields. An axial shaft is disposed in rotating relationship with at least one gimbal supported magnet that reciprocates in relation to the axial shaft. At least one rotor magnet is disposed to rotate in relation to the axial shaft in response to non-linear movement of the at least one gimbal supported magnet. A plurality of rotor magnet units may be proximally disposed to rotate about separate axial shafts, with each rotor magnet unit having a rotor magnetic field influenced by the non-linear movement of the at least one gimbal supported magnet disposed proximal to each rotor magnet unit. Movement of the each gimbal supported magnet creates repulsion and attraction of each respective rotor magnet, with inducement of axial shaft rotation, thereby producing rotational movement that is harnessed to perform work. Also disclosed are combinations of rotor magnet units disposed to rotate about respective axial shafts upon the reciprocation of a central gimbal supported magnet, for utilization in the operation of a fluid transfer pump and/or an electric generator.
