Abstract
An adaptive winding configurations and control method is disclosed for the electromagnetic poles of electric machines, including motors and generators. Motors utilizing the inventive adaptive winding configuration and control method are able to dynamically adjust their operating characteristics to maintain a constant rated power over a large operating speed range with high efficiency. Generators employing the inventive adaptive winding configuration and control method are able to dynamically adjust their operating characteristics in response to a variable driving force to achieve maximum power conversion efficiency. These generators are also able to dynamically change their output voltage and current (thus charging speed) when charging batteries depending on the charged state of the battery, and on the expected duration of the input power.
