Title
(EN) MOTOR STATOR
Abstract
(EN) A motor stator comprises multiples teeth (20 20  20 ) and multiple arch bridge portions (30 30  30 ) separately connected between tooth roots (21) of two adjacent teeth. Each arch bridge portions (30 30  30 ) has an arch ring (31 31 ) extending along at two adjacent side edges of a preset parallelogram. The motor stator also comprises multiple enlarged area ports (a) separately located on the positions of the tooth roots of the teeth (20 20  20 ). The arch bridge portions (30 30  30 ) are located beyond the ranges of the corresponding enlarged area ports (a). The motor stator is formed by stacking up multiple small stators (10 ). At least two pushing and cutting ports (40 ) are respectively located between tooth roots of two adjacent teeth (20 ) and the pushing and cutting ports (40 ) separate the adjacent teeth (20 ). By expanding the space at two ends of the arch bridge portions the motor stator increases the passing space of the magnetic field.
