ELECTRIC MOTOR GENERATOR WORKING WITHOUT BEARINGS

摘要

An electrical motors/generator system working without a bearing between the rotor and the stator is provided. The stator may substantially surround the rotor within a rotary cavity. The rotor may include a flywheel coupled to a flywheel shaft, wherein the flywheel shaft extends beyond the rotary cavity so as to rotably connect to mounted magnetized plates. The opposing ends of the flywheel shaft may be received by shaft recesses formed into each magnetized plate, wherein each recess is dimensioned and adapted to receive electromagnet and electromagnet coils along portions of the flywheel shaft in the shaft recess. Adjacent to the received electromagnets, an annular magnet is disposed about a portion of the flywheel shaft not in the shaft recess. The magnets are thus in the close proximity to the electromagnet/coils so that magnetic fields generated by the electromagnet coils generate a force on the magnets arranged around portions of the flywheel shaft of the rotor thereby causing the rotor to rotate in a magnetically controlled manner. Underneath the stator and the rotor a bottom magnet may be disposed so as to decrease the effect of the rotor self-weight

1. An electric motor-generator comprising:
a stator extending from a front sidewall to a rear sidewall; a rotary cavity formed between the front and rear sidewalls of the stator; a rotor centered in the rotary cavity, wherein the rotor comprises:
a flywheel shaft having a front end and an opposing rear end, each end extending beyond the rotary cavity, wherein each end is rotably connected to a magnetized plate;a flywheel coupled to the flywheel shaft; andan axis of rotation oriented generally parallel to the front and rear sidewalls; a shaft recess formed into each magnetized plate, wherein each shaft recess provides a plurality of electromagnets and electromagnet coils disposed about each end of the flywheel shaft; and an annular magnet dispose near each end of the flywheel shaft not in its respective shaft recess.
