enerated voltage is a maximum when the inductors arein the position shown and one side of each coil is cutting lines offorce, the voltage is zero when the poles are in position y and is amaximum again but in the opposite direction when the polesare in the position z and the other side of each coil… … Fig. 277.—Magneto alternator. ductors is equivalent to a ten-pole revolving field machine. Sinceonly one side of each coil is active at any instant in the case of theinductor alternator, it is the heavier of the two machines for agiven output and is therefore used only when simplicity of…
