Abstract

Un motor EC con un estator y un rotor montados en un eje. El motor tiene un sistema de enfriamiento, un alojamiento de estator sobremoldeado, y un rotor optimizado. El estator tiene dientes con bobinas electromagnéticas enrolladas. Los dientes y las bobinas se distribuyen circunferencialmente con espacios entre bobinas adyacentes. El estator está sobremoldeado con plástico que forma pasajes de enfriamiento axialmente orientados entre secciones de bobina adyacentes. Luego, un ventilador impulsor aspira aire hacia el motor a través de entradas de aire conectadas a pasajes de aire. El ventilador impulsor dirige el aire a través de los pasajes de enfriamiento axialmente orientados en el estator y salidas de aire. Un rotor interior optimizado tiene imanes permanentes y laminados de acero al silicio espaciados circunferencialmente y que se extienden hacia afuera desde un eje central. Los imanes de forma rectangular se interponen en los espacios entre los laminados. Los imanes en forma de cuña están alineados radialmente con los laminados y entre los laminados y el cubo.
