For most constant-speed applications the operating characteristics of polyphase motors are superior to those of ... However, the fact that the alternating current is continually reversing introduces complications. Considering any given armature conductor located in the flux of a field pole, we know that reversing either the current or the flux reverses the direction of the force produced, and hence theanbsp;...
