Title
(EN) MOTOR STATOR
(FR) STATOR DE MOTEUR
Abstract
(EN) A motor stator structure includes multiple teeth 20, 20', 20" and multiple arched bridge sections 30, 30', 30" respectively connected between the tooth roots 21 of the adjacent teeth. Each of the arched bridge sections 30, 30', 30" has an arched section 31, 31' 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 20, 20', 20". Each of the arched bridge sections 30, 30', 30" is positioned outside the range of the corresponding enlarged section a. The motor stator structure is composed of multiple small stators 10" stacked on each other. At least two punched splits 40" are respectively positioned between the tooth roots of two adjacent teeth 20" to separate the adjacent teeth 20". The space of two ends of the arched bridge section is enlarged to increase the pass space of magnetic field.
