Alternator

Alternator, comprising in combination a housing, a hollow stator with windings fixed in said housing and having a conical inner shell, an axial rotary shaft in said housing, a rotor with a conical outer shell on said shaft and operating in conjunction with the conical inner shell of said stator, a slide between the shaft and the rotor for the axial motion of said rotor over the shaft and in said stator for the current control, a disc mounted on said shaft and dispersed near one end of said rotor, a compression spring for sliding said rotor over the shaft into said stator and arranged between said rotor and disc, a thrust plate movable over the shaft and disposed near the other end of said rotor, a thrust ring arranged around said shaft, a compression spring for sliding said rotor over the shaft out of the stator and arranged between said thrust plate and thrust ring, setting bolts working in conjunction with said thrust ring for the adjustment of the compression of said compression spring, and a centrifugal voltage controller for fine-adjusting the compression of said compression spring sliding said rotor out of the stator and keeping the induced current voltage the same, said controller fixed on said shaft and having swivel arms with weights to exert a pressure on the adjacent thrust plate and compression spring.
