Abstract:
A stator assembly structure of a direct current brushless motor, comprising:a coil seat, wound with coils and provided with a fitting hole; an upper pole plate, located under the coil seat, the lower pole plate provided with pole ends and a magnetic conducting tube; a lower pole plate, located under the coil seat, the lower pole plate provided with pole ends and a magnetic conducting tube; at least one upper magnetic conducting plate, having pole ends and a positioning hole, the positioning hole allowing passage of the magnetic conducting tube of the upper pole plate, and the pole ends of the at least one upper magnetic conducting plate being provided with side walls extending toward a vertical direction; the magnetic conducting tubes of the upper pole plate and the lower pole plate passing through the upper magnetic conducting plate and the lower magnetic conducting plate, and then combining with the fitting hole of the coil seat, and said magnetic conducting tubes of the upper pole plate and the lower pole plate each having an outer diameter greater than the diameter of the positioning holes of the upper magnetic conducting plate and the lower magnetic conducting plate, so that the magnetic conducting tubes may be combined in a tight fit manner.
