Abstract
Official abstract text for this publication.
Dynamic reconfiguration-switching of motor windings is optimized between winding-configurations. Acceleration is traded off in favor of higher velocity upon detecting an 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for switching motor windings within an electric 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 for trading off acceleration 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 thereby preventing a total b…
