ABSTRACT:
An improved direct-current electrical dynamotor wherein the brushes are sufficiently wide to simultaneously abut a multiplicity of commutator segments. The winding sections extend independently from one commutator segment to a commutator segment that is approximately 180 electrical degrees away whereby the brushes each simultaneously collect a plurality of currents induced in the winding sections extending to the commutator segments abutted by the pair of positive and negative brushes. Each pair of brushes is installed on each side of the magnetic neutral. All of the coil sections are completely independent of each other with no electrical interconnections aside from the commutator brushes.
