Abstract

Dual Halbach array element electric motor/generator with paired enhanced sides and substantially contiguous vertical and horizontal electromagnetic cores, comprised of a plurality of electromagnets arranged in Halbach array sequence, with horizontal cores equipped with fork-like prongs to provide substantial contiguity with vertical cores, assembled to serve as a circular or linear stator, rotor, or both, and a plurality of permanent magnets likewise arranged in a Halbach array sequence, assembled to serve as a circular or linear stator or rotor where required, with the enhanced sides of each Halbach array element, as rotor and stator, are paired together.

Claims

1. A method for harnessing both sides of a Halbach array sequence of electromagnets having substantially contiguous vertical and horizontal cores, as a component within a dual Halbach array element electric motor/generator with paired enhanced sides, to enable tandem functionality with an external or integrated complementary device, such as another Halbach array rotor, comprising:

(a) designing and assembling electromagnets arranged in Halbach array sequence, said electromagnets having vertical cores and horizontal cores, said horizontal cores having fork like prongs arranged to provide substantial contiguity with said vertical cores, said electromagnets further arranged in a manner that keeps both sides clear of obstacles,

(b) separating phase wiring of vertical and horizontal electromagnets, and attaching each set to dual channel motor controllers, or multiple motor controllers working simultaneously via a bus or signal network, or other similar apparatus,

(c) providing the inactive side of said electromagnets arranged in Halbach array sequence with an external or integrated complementary device matching that on the active side, such as an additional rotor, which may have electromagnets or permanent magnets, wherein the additional rotor may also be configured with its electromagnets or permanent magnets as Halbach arrays,

(d) switching the polarity, only of horizontal electromagnets, once, to cancel out the magnetic forces on the previously active side and elastically transfer the focus and power of said electromagnets arranged in Halbach array sequence to the other, formerly inactive side, towards said complementary device,

(e) switching or commutating simultaneously thereafter, via said motor controllers or similar apparatus, both vertical and horizontal electromagnets as needed, and

(f) repeating as necessary, the foregoing switching process for the correct operation of the motor/generator or device, with the elastic reallocation of magnetic flux in the cancelled and enhanced sides of electromagnets arranged in Halbach array sequence having substantially contiguous vertical and horizontal cores, and essentially function as a dual-sided stator component.
