METHOD, COMPUTER PROGRAM PRODUCT AND CONTROLLER FOR STARTING-UP A SWITCHED RELUCTANCE MOTOR, AND ELECTRICAL APPARATUS IMPLEMENTING SAME |
摘要 |
A method of starting-up a switched reluctance, SR, motor is provided. The method comprises simultaneously energizing a plurality of phases at a first time point with respective phase voltages that are substantially the same, until the motor rotor is stabilized in alignment with either one of the plurality of phases; simultaneously de-energizing the plurality of phases at a second time point that follows the first time point; monitoring a decrease of respective phase currents in the plurality of phases from a third time point that follows the second time point by a first predetermined time interval; determining a phase of alignment of the rotor using evaluation of the decrease of the phase currents following simultaneous de-energizing of the plurality of phases; and, initiating rotation of the rotor from the determined phase of alignment of the rotor. |

1. A method of starting-up a switched reluctance, SR, motor having a rotor and a stator, wherein the stator has a plurality of coils, wherein electrically coupled coils form a plurality of phases with at least a first phase and a second phase, the method comprising:
simultaneously energizing the plurality of phases at a first time point with respective phase voltages that are substantially the same, until the rotor is stabilized in alignment with either one of the plurality of phases; simultaneously de-energizing the plurality of phases at a second time point that follows the first time point; monitoring a decrease of respective phase currents in the plurality of phases from a third time point that follows the second time point by a first predetermined time interval; determining a phase of alignment of the rotor using evaluation of the decrease of the phase currents following simultaneous de-energizing of the plurality of phases; and, initiating rotation of the rotor from the determined phase of alignment of the rotor. |
