Abstract
A stator assembly includes a stator core. The stator core includes a yoke and teeth. Each of the teeth includes a neck and a tip. The neck includes a first stacking portion, a second stacking portion, a first plane and a second plane. The first stacking portion and the second stacking portion are arranged opposite to each other, and the first plane and the second plane are arranged opposite to each other. The first stacking portion and the second stacking portion are formed by stacking silicone steel sheets of the neck, and the first plane and the second plane are outer surfaces of silicone steel sheets at two terminal ends of the neck in a stacking direction.
