Abstract

Abstract An electric motor module for converting electromagnetic energy into rotational mechanical energy having at least one snap-in electromagnetic coil fixed radially about a rotating member on a shaft with the north-south polar axis disposed circumferentially relative to the shaft. A printed or laminated circuit plate takes the place of the usual hub commutator and is fastened on one side of the member to complete the circuit with the coil. The shaft is rotatably coupled to a transparent frame having a plurality of fixed magnetic members also having their north-south polar axis circumferentially disposed about the shaft and sufficiently adjacent said coil to provide magnetic interaction between the coil and the fixed magnetic members for rotating the shaft. Contact members mounted on one or both side plates constituting the frame extend to the contact surface of the circuit plates thereby completing the circuit for the reception of electrical current. Terminal posts also used as plugs either receive current wire or a negative wire for use of electricity or plug into another module to multiply the H.P. rating of the motor.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 134 words
An electric motor comprising: a stator frame; contact brushes in said frame; a shaft rotatably mounted in said frame; a rotor keyed on said shaft surrounded by said frame; a plurality of individual electromagnetic coils plugged in said rotor and spaced from the axis of said shaft and moveable in a circumferential path about said shaft, the magnetic north-south polar axis of each coil aligned substantially circumferentially about said shaft axis; a disc-like commutator carrying a printed circuit removably mounted on said rotor, said disc having alternate insulated and conductive areas and being contacted by said brushes; a plurality of magnetic members in said frame, the magnetic north-south polar axis of each member aligned substantially circumferentially to said shaft axis and sufficiently adjacent the path of said coils to electromagnetically interact with said coils.
Claim 2
Dependent Claim 134 words
An electric motor comprising: a stator frame; contact brushes in said frame; a shaft rotatably mounted in said frame; a rotor keyed on said shaft surrounded by said frame; a plurality of individual electromagnetic coils plugged in said rotor and spaced from the axis of said shaft and moveable in a circumferential path about said shaft, the magnetic north-south polar axis of each coil aligned substantially circumferentially about said shaft axis; a disc-like commutator carrying a printed circuit removably mounted on said rotor, said disc having alternate insulated and conductive areas and being contacted by said brushes; a plurality of magnetic members in said frame, the magnetic north-south polar axis of each member aligned substantially circumferentially to said shaft axis and sufficiently adjacent the path of said coils to electromagnetically interact with said coils.
Claim 3
Dependent Claim 46 words
A motor according to claim 1, wherein said magnetic members are of general ''''c'''' shape and are positioned opposite one another thereby defining an ''''o'''' shaped arcuate path in which said rotor rotates whereby maximum flux density is provided, said stator frame completely surrounding said members.
Claim 4
Dependent Claim 60 words
A motor according to claim 1, wherein said rotor consists of a ring gear having internal toothing, there being a central gear keyed on a rotating shaft in said frame and equally spaced planetary gears mounted on stationary shafts between the ring gear and the central gear, said planetary gears being enmeshed with said ring gear and said central gear.
Claim 5
Dependent Claim 23 words
A motor according to claim 3, having a contact plate with a plurality of contact fingers, said plate rotating with said rotating shaft.
Claim 6
Dependent Claim 15 words
A motor according to claim 3 wherein said frame is of transparent, heat resistant plastic.
Claim 7
Dependent Claim 27 words
A motor according to claim 1, wherein said coils are encased in a tellurium-copper casing with a sheet of insulating material between the coils and the casing.
Claim 8
Dependent Claim 15 words
A motor according to claim 1, wherein said coils are encased in a plastic casing.
Claim 9
Dependent Claim 27 words
A motor according to claim 3 having a plurality of equally spaced idler wheels in contact with the outer periphery of said ring gear for minimizing friction.
