Abstract
Abstract A magnetic motor having at least one drive unit including first and second stationary magnets arranged with inverse directions of polarity and a movable magnet mounted for movement within the magnetic fields of the first and second stationary magnets. A diverter device is switched between two positions for alternately diverting the magnetic fields of the first and second stationary magnets. The movable magnet is alternately switched into alignment with the first and second stationary magnets, while the diverter diverts the magnetic field from the other magnet. In this manner a repulsion force is created which causes the continued movement of the movable magnet.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A magnetic motor having at least one magnetic drive unit, the drive unit comprising: first and second stationary magnets arranged with inverse directions of polarity; a movable magnet mounted for rotation within the magnetic fields of said first and second stationary magnets, said movable magnet being mounted about an axial member so as to enable its direction of polarity to be inversed as said movable magnet rotates; diverter means for alternately diverting the magnetic fields of said first and second stationary magnets for preventing such magnetic fields from influencing said movable magnet so as to enable only said stationary magnet having its direction of polarity in opposition with the polarity of said movable magnet to influence said movable magnet by creating a repulsion force between said magnets and thereby causing the movement of said movable magnet.
Claim 2
Dependent Claim
136 words
A magnetic motor having at least one magnetic drive unit, the drive unit comprising: first and second stationary magnets arranged with inverse directions of polarity; a movable magnet mounted for rotation within the magnetic fields of said first and second stationary magnets, said movable magnet being mounted about an axial member so as to enable its direction of polarity to be inversed as said movable magnet rotates; diverter means for alternately diverting the magnetic fields of said first and second stationary magnets for preventing such magnetic fields from influencing said movable magnet so as to enable only said stationary magnet having its direction of polarity in opposition with the polarity of said movable magnet to influence said movable magnet by creating a repulsion force between said magnets and thereby causing the movement of said movable magnet.
Claim 3
Dependent Claim
26 words
A magnetic motor as defined in claim 1 wherein said first and second stationary magnets are adjacently arranged and laterally offset with respect to one another.
Claim 4
Dependent Claim
63 words
A magnetic motor as defined in claim 2 wherein said first diverter means includes a plate member with separate first and second bars of a first metal material arranged therein and means for reciprocally moving said plate member such that said first and second bars are alternately positioned adjacent to said first and second stationary magnets, respectively, for interrupting the magnetic fields thereof.
Claim 5
Dependent Claim
39 words
A magnetic motor as defined in claim 3 wherein said stationary magnets and said movable magnet are horseshoe-shaped magnets and said magnets are arranged such that the open-side of said stationary magnets face the open-side of said movable magnet.
Claim 6
Dependent Claim
64 words
A magnetic motor as defined in claim 3 wherein said means for removing said plate member includes a spring coupled to one side of said plate member so as to move said plate member in one direction and solenoid actuated means coupled to the opposite side of said plate member for selectively applying a force for moving said plate member in an opposite direction.
Claim 7
Dependent Claim
102 words
A magnetic motor as defined in claim 3 wherein: there are a plurality of said drive units; each plate member of said units has an arm extending from one side thereof; said arms are coupled to a common rotatable shaft; said shaft has a plurality of cams, each coupled to a respective one of said arms, and said shaft and said cams constitute said means for moving said plate member; and said movable magnets are connected to a common said axial member, said movable magnets being mounted on said axial member so as to be offset from one another by equal angles.
Claim 8
Dependent Claim
64 words
A magnetic motor as defined in claim 3 wherein: there are a plurality of said drive units, said drive units being aligned along a common plane, said plate members of said units being connected together so as to be moved in synchronism; and further comprising a gear member concentrically mounted on each of said axial members, said gear members being interconnected with one another.
