This invention proposes a method to eliminate disadvantages infesting prior art three-phase synchronous and induction electric motors. It also proposes a motor the stator and rotor of which are energized from separate three-phase high frequency electronic power sources. The invented motor could also operate as an angular positioner to advance or retard rotor precisely. The proposed frequency increase is behind replacement of traditional ferromagnetic cores in the stator and rotor with linear magnetic materials such as composites, plastics or even air. In the proposed motor traditional transfers of energy, from stator to rotor by induction, have been eliminated thus stator and rotor are energized from separate energy sources to improve the Torque v. speed and current vs. speed characteristics. The improvement includes torque independent from speed and current depending just from the load. Therefore the starting up current is not higher than of the max operating current. Also the proposed engine operates well on very slow speeds e.g. 0.000,001 rpm or very high speeds e.g. above 125,000 rpm. The max speed is limited by a stress caused by inertia of a fast rotating mass of the rotor, while the low speeds are limited by the quality of quartz used to produce high frequency three phase electric powers. Finally the invention discusses a dual high frequency three phase electronic power source of electricity to energize stator and rotor independently. The application of proposed motor is much wider than that of traditional induction or synchronous motors and includes areas not possible in prior art.
