Full-voltage AC magnetic multi-speed controllers are designed to control recon- nectable squirrel-cage induction motors for operation at two, three or four differ- ent constant speeds depending on the construction of the motor . These con- trollers are available in combination and non-combination types. The speed of an induction motor is a function[...]

Auto T ransformer Starter Operation At starting, the auto transformer reduces motor terminal voltage to 50, 65, or 80 percent of line voltage. For a timed inter- val, a segment of the transformer coil is connected in series (as an inductor) with the motor . Then a contactor automatically connects the motor across the line and shorts out the inducto[...]
