  • Publication number: 20210017977
    Abstract: An air blowing device includes a duct portion and a passage variable device. The duct portion forms a main passage through which an air flow passes, and an outlet is defined downstream of the main passage to blow out the air flow. The passage variable device is configured to change a passage area of the main passage so that the air flow becomes a pulsating flow and is blown out from the outlet.

  • Publication number: 20170324304
    Abstract: In an electric motor, a magnetic bearing generates an electromagnetic force between multiple permanent magnets and a coil and rotatably supports an other side of a rotation shaft in an axis line direction. The rotation shaft is configured to be capable of being inclined with a rotation center line using a bearing side of the rotation shaft as a fulcrum. An electronic control device controls a current that flows to the coil such that an axis line of the rotation shaft approaches the rotation center line due to a supporting force which is the electromagnetic force between the multiple permanent magnets and the coil. Accordingly, the rotation shaft is rotatably supported to be freely rotatable by a magnetic bearing and the bearing.
