Abstract:
1. A method for switching motor windings within a motor using a processor device, the method comprising: optimizing a dynamic reconfiguration-switching of a plurality of motor windings between a plurality of winding-configurations by selectively lowering resistance of a constantly used portion of one of the plurality of motor windings for trading off acceleration in favor of higher velocity upon detecting the motor is at an optimal angular-velocity for switching to an optimal lower torque constant and voltage constant thereby preventing a total back electromotive force (BE MF) from inhibiting further acceleration to a higher angular-velocity; and using m simultaneous-linear equations, having m number of unknown variables, for determining a plurality of voltage constants, the optimal time, and the optimal angular-velocity for performing the dynamic reconfiguration-switching between each of the plurality of winding-configurations, wherein a number of the m simultaneous-linear equations increases, starting with one equation for a three-winding- configuration of the motor and adding an additional simultaneous equation for each additional one of the plurality of winding-configurations, and a number of the plurality of voltage constants equal to the correlating one of the plurality of winding-configurations.
