of these slotsdrawn to a larger scale. Two wires onthe armature, at a distance apart equalto the distance between adjacent northpoles, and subtending the angle q, Fig.105, have induced in them two electro-motive forces. These electromotive forcesare to be thought of as differing in phaseby 360°,… … Fig. 105. Enlarged Sectionof_Fig. 104 111 100 ALTERNATING-CURRENT MACHINERY Therefore, the phase difference of the electromotive forces inducedin the wires placed in slot a, and those induced in the wires placed in slot b, is — X 360; or, in other words, this angle is: q width of tooth + width of…
