Abstract
Abstract A direct current electric motor system employs a controlled energizing circuit having a plurality of sources of direct current, one of which is connected with alternate ones of the other sources to energize the stator winding while the other of the alternately connected sources is simultaneously placed in a charging circuit. The motor comprises a plurality of stators and a corresponding plurality of rotors with the rotors mounted on the common shaft and angularly disposed relative one another so that there is a time overlap in their periods of influence by their corresponding stator field windings.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A direct current motor system comprising: a motor including a stator having at least one pair of pole members, a rotor mounted for rotation within said stator, and a pair stator windings permanently serially connected and individually disposed on separate ones of said pole members, first, second and third sources of direct current for energizing said stator windings, first switching means for connecting said first and alternately one of said second and third sources to said stator windings, diode means, second switching means for alternately connecting the other of said second and third sources and said diode means to said windings in an opposite polarity sense to the connection of said first source, and third switching means for interrupting the circuit established by said first switching means to effect a changing relationship between said windings and said alternately connected other source of direct current.
Claim 2
Dependent Claim
144 words
A direct current motor system comprising: a motor including a stator having at least one pair of pole members, a rotor mounted for rotation within said stator, and a pair stator windings permanently serially connected and individually disposed on separate ones of said pole members, first, second and third sources of direct current for energizing said stator windings, first switching means for connecting said first and alternately one of said second and third sources to said stator windings, diode means, second switching means for alternately connecting the other of said second and third sources and said diode means to said windings in an opposite polarity sense to the connection of said first source, and third switching means for interrupting the circuit established by said first switching means to effect a changing relationship between said windings and said alternately connected other source of direct current.
Claim 3
Dependent Claim
23 words
A direct current motor system as set forth in claim 1, wherein said first, second and third sources of direct current are batteries.
Claim 4
Dependent Claim
20 words
A direct current motor system according to claim 1, comprising commutator switch means including said first and second switching means.
Claim 5
Dependent Claim
28 words
A direct current motor system according to claim 1, wherein said third switching means comprises a commutator for momentarily opening the circuit established by said first switching means.
Claim 6
Dependent Claim
181 words
A direct current Motor system according to claim 1, comprising a plurality of other stators each of which has at least one pair of pole members, a plurality of other rotors individually associated with said other stators, all of said rotors mounted for mutual rotation and angularly displaced from one another, a plurality of pairs of other windings permanently serially connected and disposed on separate pairs of said pole members of said other stators and connected to said first and second switching means, and a plurality of other diode means each of said other diode means associated with a separate pair of said other windings, each of said diode means connecting its associated pair of windings to said second switching means, and wherein said third switching means includes a plurality of contacts each of which is connected between a separate pair of said stator windings and said first source of direct current, whereby said pairs of windings are energized out of phase with one another and deliver charging current to said other alternately connected source out of phase with one another.
Claim 7
Dependent Claim
31 words
A direct current motor system according to claim 5, comprising a shaft commonly mounting all of said rotors, said rotors being angularly displaced on said shaft with respect to one another.
