Outline of Final Research Achievements |
This study examine the design approach of a dual winding wound-field synchronous machine under a new harmonic voltage injection-based sensorless drive at low speeds. In the proposed sensorless control method, the principle of high-frequency current generation for rotor postition estimation has not been theoretically clarified. In this study, the principle of high-frequency current generation is clarified both experimentally and analytically using a 16-pole-96-slot machine. The correlation between motor geometry, local magnetic saturation, dynamic inductance characteristics, and control stability will be systematically organized. From the results, motor design guidelines that maximize the position sensorless operation range are derived.
