Abstract: A calculation function, which optimizes a dynamic reconfiguration-switching of motor windings between winding-configurations, is dynamically configured. Acceleration is traded off in favor of higher velocity upon detecting the electric motor is at an optimal angular-velocity for switching to an optimal lower torque constant and voltage constant. The total back electromotive force (BEMF) is prohibited from inhibiting further acceleration to a higher angular-velocity.
