ABSTRACT:
A commutatorless DC machine has axially oriented magnetic flux in the air gaps between interleaved stator and rotor disks, and the rotor disks carry one or more radially oriented armature winding elements consisting of electrical conductors serially interconnected in serpentine fashion and terminated at a pair of slip rings. The magnetic flux incident upon the two opposed planar surfaces of any one rotor disk are oppositely directed, producing electromotive forces or torques which are directly additive, resulting in heretofore unrealized electromechanical transducer action. A number of illustrative and preferred embodiments describe single or multiple rotor disk configurations, and further describe armature winding arrangements having various numbers of individual armature winding elements arranged in parallel between the slip rings. The resulting DC machines exhibit superior electrical and mechanical performance due to, among other factors, the absence of limitations imposed by commutation; they also may be designed for a wide range of electrical and mechanical requirements simply by the addition or deletion of disk sections and/or armature winding elements.
