Stator winding structure of brushless coreless disk permanent magnetic motor and motor with the stator winding structure

Abstract

The invention relates to a brushless coreless disk permanent magnetic motor and a stator winding structure therein; the brushless coreless disk permanent magnetic motor comprises two groups of unit coil sets, wherein the unit coil sets are staggered in included angles and laminated downwardly in order along a clockwise direction to form a sealing annular structure; each unit coil set includes three coils that are staggered in the included angles and laminated upwardly in order along the clockwise direction; each coil includes a pair or more than a pair of magnet strafing edges that are straight-line segments, and internal-external invalid edges connected with inner and outer end portions of the magnet strafing edges; the magnet strafing edges of each coil are arranged radially and circumferentially to form a toroidal surface; all magnet strafing edges of the winding are located in the same plane and consistent in height; and the internal-external invalid edges of each coil are laminated mutually to form internal and external superimposition parts of a lower bump. Because all magnet strafing edges of the winding are located in the same plane and consistent in height, the slot fullness of the coils and the utilization rate of the generated electromagnetic field are higher, the efficiency of the motor is improved greatly and the heat productivity of the motor stator is reduced.

Description

technical field [0001] The invention relates to a component of a brushless iron-coreless disc permanent magnet motor, in particular to a winding structure of a stator therein and a motor with the stator winding structure. Background technique [0002] Motor stators now include iron-core motors and iron-less motors. The stator of a motor with an iron core is composed of an iron core and a coil wound on the iron core. Due to the irregular shape of the part of the coil exposed on the top and bottom surfaces of the iron core, there is a little hindrance when installing the rotor in the stator, that is, The rotor cannot be installed, or even if it is installed, the operation of the rotor will be affected. In addition, when the stator is installed in the stator shell, these irregularly shaped partial coils that expose the top and bottom surfaces of the iron core will also affect the installation of the stator itself. Therefore, in After the stator is socketed with wires each time...
