Abstract

Methods for starting an AC motor with a variable speed drive and switching the motor to a higher voltage power source are described. Provided are AC motors with a stator having a plurality of coils, the plurality comprising a complete set of coils for each phase, the complete set comprising a first set of coils comprising first groups of coils connected in series, or parallel, or a combination, and a second set of coils comprising second groups of coils connected in series, or parallel, or a combination, wherein the output of a variable speed drive is connected to a tap on the complete set of coils such that the AC motor may be started with a variable speed drive, and an output of the power line is connected to the series of the first and second sets of coils.
