Abstract:
A kind of electric machinery by using centrifugal force to produce rotor axial activation modulation is between the rotating shaft of the electric machinery and the electric machinery rotor or between the electric machinery rotor and the stator, or between the rotating shaft of the electric machinery and the stator, there is installed an axial activation mechanism by using centrifugal force and there is installed an axial pre-stressed spring, and to the rotating shaft of the electric machinery there can be selectively installed an axial position limitation structure, and by making use of the speed of the electric machinery rotor, to modulate the electric machinery rotor to produce corresponding axial displacement, and further to modulate the characteristics of the electric machinery between the electric machinery rotor and the electric machinery magnetic field, Its main constituents include:Electric machinery magnetic field F100: Including the constituents of DC or AC generators or motors structures; These structures include: F1: Between the poles of the electric machinery magnetic field and the electric machinery rotor of which the electric machinery magnetic field exhibits normal stable even distribution; or F2: Between the poles of the electric machinery magnetic field and the electric machinery rotor of which the axial single side or double sides exhibit different electric machinery magnetic field intensity; or F3: Between the poles of the electric machinery magnetic field and the electric machinery rotor of which the axial single side or double sides exhibit different gap structures with electric machinery rotor; or F4: Between the poles of the electric machinery magnetic field and the electric machinery rotor whose axial single side or double sides consist of multiple permanent magnetic poles or magnetic poles excited by magnetic windings W100 or combinations of both which consist of axial serial structures; or F5: The structures formed by two or more of the structures described in F1 through F4; The electric machinery rotor R100: Including single or mixed electric machinery rotors consist of various commonly used AC or DC generators or motors such as permanent, salient, hysteresis, wound, brush, turbo, squirrel-cage type AC or DC or brush or brushless, synchronous or asynchronous; Centrifugal pulling structure FCD100: Including the structures consist of commonly used axial pulling structure due to centrifugal force, and with pre-stressed spring SP100 which exhibit regression during deceleration that will pull the rotor to produce corresponding displacement depending on the speed of the electric machinery rotor, which will alter the relative positions between the electric machinery rotor R100 and electric machinery magnetic field F100, which will produce the relative settings between the electric machinery rotor R100 and the electric machinery magnetic field F100.
