Abstract:
A two-dimensional electric motor comprising:a first array of a multiplicity of permanent magnets having north and south poles distributed in both first and second directions;a second array of a multiplicity of permanent magnets having north and south poles distributed in both said first and second directions;wherein said north poles in said first array are aligned with said south poles in said second array and said south poles in said first array are aligned with said north poles in said second array; andat least two coils, each coil having at least a portion thereof between said first and said second arrays of permanent magnets, each coil being responsive to electric current to cause said coils and said first and said second arrays of permanent magnets to move relative to one another such that said first and said second arrays of permanent magnets are stationary with respect to each other, andwherein an edge permanent magnet on an edge of said first array has a strength approximately equal to one-half a strength of an interior permanent magnet which is part of said multiplicity of permanent magnets in said first array.
