ロスフローフアン。 The end of the rotating cross-flow fin, which rotates in one direction and has a large number of fins arranged in an annular shape to suck in air from the circumferential direction and send air in the same circumferential direction, can be freely rotated to the main body of the single-phase brushless DC cross-flow fan. The single-phase brushless DC cross-flow fan body is arranged to face the circumferential surface of the rotating cross-flow fin so that the position where the wind is sucked in in the circumferential direction and the position where the wind is sent are at different angles. and an end wall for rotatably supporting the end of the rotating cross-flow fin, and approximately the center in the axial direction of the rotating cross-flow fin for rotatably supporting the rotating cross-flow fin. A cylindrical rotating shaft with an extremely small diameter that rotates integrally with the cylindrical shaft is formed, and 2P (P is an integer of 1 or more) magnetic poles of N and S poles are provided on the inner circumference of the cylindrical rotating shaft. A single-phase stator armature is disposed on the fixed side facing the field magnet with a radial gap in between, and the field magnet is rotated as a unit. one position detection element for detecting a magnetic pole and switching the energization of the armature coil of the stator armature; and energization for switching the energization of the armature coil based on a signal from the position detection element. A control circuit is provided, and a self-start processing means for self-starting rotation of the field magnet is provided, so that a single-phase brushless DC motor and an energization control circuit for controlling energization thereof are built in the rotating shaft. Single phase brushless DC cross flow fan.
