A stator core of a fan motor comprises: a back yoke body; and a plurality of teeth which are spaced apart from each other inside the back yoke body, wherein each of the plurality of teeth comprises: a neck coupled to the back yoke body; and a shoe protruding from the neck and facing the outer circumference of a rotor, and each of a plurality of insulators of the fan motor comprises: a neck insulator surrounding the neck; a first barrier protruding from the neck insulator in an axial direction; and a pair of second barriers protruding from the neck insulator towards the inner circumference of the back yoke body.

In a motor stator, terminal wires of a coil are led out respectively from a feed-side and a neutral-side coil end. With three circumferentially adjacent first-, second-, and third-phase coils as one set, the leading end portion and intermediate portion of one of three terminal wires led out from the neutral side are connected to each of the remaining terminal wires. A structure wherein the first- and second-phase terminal wires are connected together in one position, and the second- and third-phase terminal wires are connected together in a different position from the one position, is adopted, thus compacting the size of one wire connection portion.

A gravity energy generator that provides a better and efficient way to use electricity as a source of power. The gravity energy generator includes a horizontal casing, a plurality of magnets and a plurality of wiring. A magnet is positioned on a midpoint of a centered shaft that is adapted to rotate along the centered shaft from an electromagnetic field from the first pair of magnets placed on the first end and the second end within the interior of the horizontal casing. Other embodiments of the gravity energy generator include a horizontal casing, a plurality of magnets, a battery and a pair of copper plates as well as a horizontal casing, a plurality of magnets and a pair of magnetic push and pull devices.

A linear generator includes a permanent magnet array having at least two magnets arranged end-to-end. A set of conductive coils is arranged around the permanent magnet array. A four-phase full wave rectifier is configured to accept alternating current inputs from the set of conductive coils and to produce one or more direct current outputs. A summing circuit is configured to aggregate the one or more direct current outputs from the rectifier to produce a combined, rectified direct current output.
