Abstract:
1. A stator structure comprising: a main body comprising: a continuous-unity cylindrical waist post having a first end and a second end; a plurality of first salients spaced at intervals, connected to the first end and located on a first plane, wherein each first salient comprises a first straight side and a second straight side, the first straight side is larger than the second straight side, and the first straight side connects the second straight side to form a first angle; and a plurality of second salients spaced at intervals, connected to the second end and located on a second plane, wherein each second salient comprises a third straight side and a fourth straight side, the third straight side is larger than the fourth straight side, the third straight side connects the fourth straight side to form a second angle, each projected first salient is placed between two adjacent second salients when the first salients project onto the second plane along the axial direction of the continuous-unity cylindrical waist post, and the continuous-unity cylindrical waist post, and the first and second salients are a monolithic piece formed by pressing, hot pressing, centrifugal molding, or integrally pressing; an insulator disposed on the continuous-unity cylindrical waist post; a coil wound around the insulator; a circuit board positioned under the second salients; and a stator bracket connected to the continuous-unity cylindrical waist post for securing the stator structure thereon.
