Abstract
A motor stator structure includes multiple teeth and multiple arched bridge sections respectively connected between the tooth roots of the adjacent teeth. Each of the arched bridge sections has an arched section extending along two adjacent sides of a predetermined parallelogram. The motor stator structure further includes multiple enlarged sections a respectively positioned at the tooth roots of the teeth. Each of the arched bridge sections is positioned outside the range of the corresponding enlarged section. The motor stator structure is composed of multiple small stators stacked on each other. At least two punched splits are respectively positioned between the tooth roots of two adjacent teeth to separate the adjacent teeth. The space of two ends of the arched bridge section is enlarged to increase the pass space of magnetic field.
