Background technique

As shown in Figure 1, the conventional motor structure includes:

A rotor 10 is combined with a rotating shaft 101 .

A shell base 11, inside the shell base 11 is provided with a rotor placement groove 111, for the rotor 10 to be placed therein, and a support piece 112 is provided at the bottom of the rotor placement groove 111, the support piece 112 can be a bearing or a shaft sleeve... and other components, One end of the rotating shaft 101 for supporting the rotor 10 rotates at its center.

A cover body 12 is arranged on the top of the housing seat 11 in a corresponding manner, and a support member 121 is arranged in the center of the cover body 12. The support member 121 can also select components such as bearings or bushings to support the other end of the rotating shaft 101 rotate in its center.

In addition, the outer peripheral wall of the housing base 11 is respectively provided with an even number of radially corresponding fixing pieces 113 for fixing the coil 13 to form a stator, and the outer peripheral wall of the housing base 11 is provided with a motor induction drive assembly 14, so that the coil 13 Form magnetic induction with the rotor 10 to drive the rotor 10 to rotate.

However, the stator of the above-mentioned motor structure must be respectively fixed on the outer peripheral wall of the housing base 11 through an even group of coils 13, thus deriving the following disadvantages:

(1) Manufacturing and assembling are inconvenient: because the stator of the conventional motor structure must fix the even groups of coils 13 on the outer peripheral wall of the housing base 11 respectively, so when the motor structure is manufactured, the even groups of coils 13 must be wound first, and then Fix the even groups of coils 13 on the outer peripheral wall of the housing 11 one by one. If the number of coils 13 is two groups, the process of fixing the coils 13 must be repeated twice. If the number of coils 13 is four groups, the process of fixing the coils 13 must be repeated four times. The process of the coil 13 not only requires several processes in manufacture, but is also relatively inconvenient in assembly.

(2) The coil is easy to fall off: the coil 13 of this conventional motor structure is fixed on the outer peripheral wall of the housing base 11, and only relies on the fixing member 113 to stick to it. If it is affected by the vibration generated by the rotation of the rotor 10 for a long time, it is easy. And fall off.

(3) Difficulty in alignment: The even group of coils 13 and the motor induction drive assembly 14 of this conventional motor structure are independently fixed on the outer peripheral wall of the housing 11, so when assembling, special attention must be paid to whether there is accurate alignment between these components. Otherwise, it will cause difficulty in starting the motor.

Therefore, in order to completely solve the problems of the conventional motor structure, it is necessary to think more actively and develop a new motor structure to simplify the manufacturing and assembly process of the motor structure, reduce the manufacturing cost and improve the production efficiency.
