DYNAMIC RECONFIGURATION-SWITCHING OF WINDINGS IN AN ELECTRIC MOTOR |
摘要 |
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. |

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 back electromotive force (BEMF) 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 the dynamic reconfiguration-switching. |
