Abstract

PURPOSE:To eliminate the static cogging due to the change in the reluctance in fitting holes which are opened through the stator yoke of a flat motor to fit stator windings or the like, by providing holes or projections in angular positions diffrent from those of the fitting holes to set inverse phases. CONSTITUTION:The flat stator windings 8 are provided on plastic bobbins 9 which have fitting holes 10. The stator windings 8 face the annular magnet of the flat brushless DC motor or the like through an axial gap and are secured on the stator yoke 7 by screws 11 engaged in the fitting holes (tapped holes) 12 of the yoke 7. If the scews 11 are nonferrous, holes 13 are provided in the angular positions different from those of the fitting holes 12. If the screws 11 are ferrous, projections 13 are provided in the angular positions. The inverse phases are thus set to eliminate the static cogging due to the change in the reluctance in the fitting holes 12.
