ADJUSTABLE ASSEMBLY OF ROTOR AND STATOR AND APPLICATIONS THEREOF WITH A VARIABLE POWER GENERATOR

摘要

A variable power generator comprises one of a stator and a rotor which is adjustably movable through an infinite number of positions from being proximate to one another so that their magnetic fields overlap to a position such that the rotor is most distant from the stator and has little overlap of magnetic field strength. The variable power generator in operation may comprise one of a rotor and a stator being out of phase with one another by an angle, for example, the one of the rotor or the stator leading or lagging the other. In this instance, a motor such as a servo motor may be used to rotationally compensate for the out-of-phase angle by radially moving the rotor with respect to the stator or vice versa. The variable power generator may be also be applied in a cam-controlled speed converter and a wind or marine hydrokinetic turbine. The variable power generator may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner). Moreover, the variable power generator may be applied to advantage in electric motors and internal combustion engines for speed control and other purposes.
