Abstract: Использование: бесконтактные электродвигатели постоянного тока предназначены для аппаратов аудио- и видеозаписи. Сущность изобретения: в двигателе магнитная система жестко установлена на валу ротора и состоит из немагнитного корпуса с размещенными внутри него элементами магнитопровода и вспомогательного магнита так, что образуется полость с однородным магнитным полем. Датчик положения ротора на датчиках Холла расположен в центральной части полости и неподвижен относительно статора. При вращении ротора с датчиков Холла снимаются строго синусоидальные сигналы, усиливаются и подаются на обмотки статора. Возникающие в обмотках токи, взаимодействуя с магнитным полем ротора, создают равномерный электромагнитный момент. Из-за относительной неподвижности магнитопровода и вспомогательного магнита магнитной системы в первом не возникают потери, связанные с перемагничиванием и токами Фуко. Поэтому магнитопровод можно выполнить из стали обыкновенного качества и нешихтованным и тем самым снизить затраты на материал и изготовление. 2 ил.
