The following problem points: Since the front and rear end walls 22 of the motor housing 20 are in a combined configuration, there is already a fitting tolerance therebetween, and the bearing 10 and the front and rear end walls 21 of the housing 20, 22 sets of perforations between 2丨〇 and 22〇 are also combined evils (the part shown by B in Fig. 1 is the combined part thereof), so another fitting tolerance will be generated, and the rotor 30 axis 31 and The two bearings 10 are pivoted and in a state, so that another matching tolerance is generated, and the combined state of such multiple tolerances obviously causes the phenomenon that the overall motor combination accuracy is difficult to meet the required standard, and then the 'motor combination state' Accuracy, the first weight of its rotor 30 axis 31 and stator set 40 The flatness between the inner walls 41, however, the former 5 M357794 describes the motor structure combination type, which will easily lead to the misalignment of the axis 30 of the rotor 30 and the loss of the precise alignment relationship between the stator group 40. Bad state, which in turn affects the operational efficiency and service life of the finished motor. Therefore, in view of the problems existing in the above-mentioned conventional motor structure, how to develop an innovative structure with more ideal and practicality, the relevant industry players must strive to develop the goal and direction of breakthrough. In view of this, the creators have been engaged in the manufacturing and development of related products for many years.
