Abstract
Abstract A magnetic motor which includes a rotor, having a preselected number of polarized magnetic poles spaced about its periphery rotating with respect to an armature having a differing, preselected number of circumferentially spaced, magnetic poles, the motor utilizing at least four pole-polarity switching circuits responsive to the rotation of the rotor each of which circuits will selectively reverse the polarity of the armature poles to continue the rotation of the rotor with respect to the armature.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A magnetic motor comprising: a rotor having 18 or whole number multiplies thereof polarized magnetic poles spaced about the periphery thereof in alternating polarity fashion; an armature comprising 16 or whole number multiples thereof circumferentially spaced electromagnetic poles connected in four selectively energizable circuits each having an equal number of poles; and polarity switching means for activating each of said four circuits responsive to the rotation of said rotor whereby a continuous force is exerted by said armature poles against said rotor poles to maintain rotation of said rotor with respect to said armature.
Claim 2
Dependent Claim
94 words
A magnetic motor comprising: a rotor having 18 or whole number multiplies thereof polarized magnetic poles spaced about the periphery thereof in alternating polarity fashion; an armature comprising 16 or whole number multiples thereof circumferentially spaced electromagnetic poles connected in four selectively energizable circuits each having an equal number of poles; and polarity switching means for activating each of said four circuits responsive to the rotation of said rotor whereby a continuous force is exerted by said armature poles against said rotor poles to maintain rotation of said rotor with respect to said armature.
Claim 3
Dependent Claim
24 words
The magnetic motor as claimed in claim 1 wherein all armature circuits are energized at one polarity or the other except during switching time.
Claim 4
Dependent Claim
46 words
The magnetic motor as claimed in claim 2, said circuit polarity switching means including means providing selectively spaced voltage pulses selectively energizing said armature circuit poles first to one polarity and then to the opposite polarity as said rotor is rotated with respect to said armature.
Claim 5
Dependent Claim
74 words
The magnetic motor as claimed in claim 3, said circuit polarity switching means further including circular grid means, and wiper means responsive to rotation of said rotor and operable with said grid means to actuate selectively one armature circuit every 20* of rotation by said rotor so that a continuing force against said rotor poles by said armature poles is maintained and a switching circuit is activated every 5* of rotation by the rotor.
Claim 6
Dependent Claim
46 words
The magnetic motor as claimed in claim 1, said circuit polarity switching means including means providing selectively spaced voltage pulses selectively energizing said armature circuit poles first to one polarity and then to the opposite polarity as said rotor is rotated with respect to said armature.
Claim 7
Dependent Claim
75 words
The magnetic motor as claimed in claim 4, said circuit polarity switching means further including circular grid means, and wiper means responsive to rotation of said said rotor and operable with said grid means to actuate selectively one armature circuit every 20* of rotation by said rotor so that a continuing force against said rotor poles by said armature poles is maintained and a switching circuit is activated every 5* of rotation by the rotor.
Claim 8
Dependent Claim
42 words
The magnetic motor as claimed in claim l, each of said armature poles having a plurality of spaced-apart openings therein, and force-exerting means positioned in said openings to exert a mechanical stress within said armature poles and thereby increase the permeability thereof.
