METHOD FOR THE OPERATION OF SYNCHRONOUS MOTORS, AND ASSOCIATED DEVICE |
摘要 |
Synchronous motors are controlled using a three-phase AC power controller. According to the invention, a fundamental wave having the desired frequency is defined for the first phase, and corresponding fundamental waves which have the same frequency as the frequency in the first phase but are out of phase by specific values are defined in the other phases. The triggering times during which the generated current pulse concurrently has the same polarity as the respective fundamental wave in two of the phases are determined for each phase and are used. Two of the three fundamental waves are generated in phase opposition when the desired frequency amounts to half the system frequency. |
