Excerpt from Alternating Current Commutator Motors: Thesis Presented to the University Faculty of Cornell University for the Degree of Doctor of Philosophy
Before discussing the performance of repulsion motors, it is well to investigate a few of the properties common to all com mutator type, alternating current machines. It will be recalled that when current ows through the armature of a direct cur rent machine, magnetism is produced by the ampere turns of the armature current, such magnetism tending to distort the ux from the field poles. In the familiar representation of the magnetic circuit of machines, - the two pole model, - the arma ture magnetism is at right angles to the field magnetism, the armature current producing magnetic poles in line with the brushes. The amount of this magnetism depends directly on the value of the armature current and the permeability of the magnetic path. When alternating current is 'used, the change of the magnetism with the periodic change in the current pro duces an alternating e.m.f. Which being proportional to the rate of change of the magnetism will be in time-quadrature to the current. The armature winding thus acts in all respects simi larly to an induction coil.
