    摘要: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a substantially cylindrical rotor core including an outer edge, an inner edge, and opposed first and second ends. The rotor further includes a first wall and a second wall defining at least one radial aperture extending radially through the rotor core. The rotor further includes at least one permanent magnet positioned within the at least one radial aperture. A first indentation is formed in one of the at least one permanent magnet and the first wall, the first indentation defining a first space between the at least one permanent magnet and the radial aperture first wall. The rotor further includes a first material positioned within the first space, the material configured to substantially prevent movement of the permanent magnet relative to the at least one radial aperture.

    摘要: A blower includes an impeller housing, an impeller rotatably secured to the housing and an electric motor. The motor has a motor housing with a central portion and a radially extending portion extending from the central portion, a venturi chamber adjacent the motor housing and opposed to the impeller housing, a stator secured to the central portion of the motor housing, a rotor rotatably secured to the central portion of the housing, and at least one heat generating electrical component secured to the radially extending portion of the motor housing. The impeller housing has a first air pressure therein and the motor housing has a second air pressure therein different that the first air pressure. The venturi housing and the motor housing define a passageway therebetween whereby the difference in air pressure generates air flow within the motor housing to cool the at least one heat generating electrical component.
