複雑でコスト高の原因となるという欠点があった。The conventional stator winding frame is as shown in Figures 1 and 2.
A resin molded piece having a U-shaped cross section was fitted into the core 3 to form the winding frame 4. However, as shown in Figure 2, magnet 2
Of the magnetic flux, only φ1 passes through the core 3, and the magnetic flux φ2 emitted from the part of the magnet 2 outside the core 3 becomes leakage flux, and there is a large amount of magnetic flux that does not effectively link to the winding 5, reducing efficiency. was bad. Therefore, in order to improve efficiency, conventionally, the plates at both ends of the core 3 were bent and the magnet 2 was bent as shown in Figure 3.
An improvement has been made in which a portion 3a facing the magnetic field is provided to utilize φ2' as an effective magnetic flux. However, this method also has the disadvantage that the number of types of laminated iron plates constituting the core 3 increases to three in order to provide the bent portion 3a, and the bent portion 3a has a complicated shape and causes high costs. Ta.
