単相ブラシレス直流クロスフローフアン。 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 air is sucked in in the circumferential direction and the position where the air is sent are at different angles. and an end wall for rotatably supporting the end of the rotating cross-flow fin, and substantially 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 the inner circumference of the cylindrical rotating shaft is provided with 2P (P is an integer of 1 or more) magnetic poles of N and S poles. A field magnet is fixed so as to rotate together, and a single-phase stator armature is arranged on the fixed side facing the field magnet through a radial gap, and the field magnet is Self-starting is possible by forming at least one of the N pole and S pole with a change in the length of the magnetic gap between the stator armatures facing each other via a radial gap, and the magnetic pole of the field magnet A single-phase brushless DC motor is built in the rotating shaft, and the single-phase brushless DC motor is equipped with one position detection element for detecting the current and switching the energization of the armature coil of the stator armature. Brushless DC crossflow fan.
