Description
The application is divisional application, and the original bill applying date is on June 19th, 2009, and application number is 200910147789.2, and denomination of invention is " motor stator and manufacture method thereof ".
Technical field
The present invention about a kind of manufacture method of motor stator, especially a kind of manufacture method of simplifying the motor stator of manufacturing process step, and by the simple motor stator of structure made by this manufacture method.
Background technology
Motor stator common on the market roughly can divide into the stator of external-rotor motor and the stator of inner rotor motor at present; Wherein the manufacturing process of the stator of inner rotor motor and the stator of external-rotor motor and structure thereof form roughly the same, therefore, below for the stator of inner rotor motor, manufacture method and the structure thereof of existing motor stator are described.
Please refer to shown in Fig. 1, the step of the manufacture method of existing motor stator 80 includes: in advance with the shaping several silicon steel sheet 81 of impact style, and several silicon steel sheet 81 is mutually stacking is combined as a whole by this; Secondly respectively at two ends of this several silicon steel sheet 81 respectively in conjunction with insulating case 82 on one and once insulating case 83; Finally prepare a coil groups 84, then this coil groups 84 is reeled simultaneously be incorporated into this several silicon steel sheet 81, the predetermined position of insulating case 82 and this lower insulating case 83 on this, to have manufactured a motor stator 80.
Generally speaking, the manufacture method of existing motor stator 80 still has shortcomings as described below:
1, manufacturing step is complicated: existing motor stator 80 during fabrication, this several silicon steel sheet 81 must be molded one by one in advance with impact style, and it is actual when carrying out assembling operation, more necessary by after respectively this silicon steel sheet 81 be combined with each other by stack manner, insulating case on this 82 and this lower insulating case 83 are incorporated into respectively the two ends of respectively this silicon steel sheet 81, rearmost can carry out the winding operation of this coil groups 84 again; Generally speaking, the suitable very complicated of steps flow chart of the manufacture method of existing motor stator 80, therefore, cause cost of manufacture improve and assembling convenience not good.
2, the bad of the finished product after manufacture: because existing motor stator 80 completes this several silicon steel sheet 81, upper insulating case 82 and lower insulating case 83 in conjunction with after operation, the winding operation of this coil groups 84 can be carried out, be limited to this several silicon steel sheet 81, the restriction of the structure space of upper insulating case 82 and lower insulating case 83, as shown in Figure 1, cannot more press close to easily causing several coils 841 of this coil groups 84 distance each other, therefore, not easily increase winding turns or the wire diameter of this coil groups 84, also namely when this motor stator 80 is applied to general motor configuration, then effectively cannot improve torsion and the rotating speed of motor.
3, coiling not easily: especially when manufacturing the stator 80 of existing inner rotor motor, because this silicon steel sheet 81 is roughly in a toroidal ring structure, this coil groups 84 then must complete winding operation in the medial surface of this toroidal ring structure, therefore, cause winding operation inconvenience, and derive the shortcomings such as a waste of time and manpower cost, moreover, easier in the process of winding operation careless this coil groups 84 of scratch, the quality of this motor stator 80 can be reduced equally.
Moreover being made up of insulating case 82, once insulating case 83 and a coil groups 84 on several silicon steel sheet 81, by the motor stator 80 completed manufactured by above-mentioned steps flow process, therefore, existing motor stator 80 has shortcomings as described below:
1, not easily axial height is reduced: motor common on the market is at present gradually towards microminiaturized direction R & D design, but this existing motor stator 80 still includes numerous and diverse component such as mutually stacking several silicon steel sheets 81 and upper and lower insulating case 82,83; Therefore, causing the axial height of this motor stator 80 to increase on the contrary, when this motor stator 80 is applied to motor configuration, by making the overall volume of motor configuration and axial height effectively reduce, causing this motor configuration to be not easily designed to more compactization.
2, run stability is not good: when this motor stator 80 is applied to motor configuration to drive a rotor to rotate, because this motor stator 80 includes silicon steel sheet 81, and this rotor is provided with and is staggered the permanent magnet formed by N/S pole, therefore, when producing relative movement between the magnetic pole strength that N/S pole and this silicon steel sheet 81 of this permanent magnet are formed, namely cogging or uneven effect can be there is, also magnetic torsion phenomenon (CoggingTorque) is namely commonly called as, particularly when the rotary speed of this rotor is slower, more easily vibrate.
Please refer to shown in Fig. 2, be TaiWan, China No. M248128 " assembled stator set mechanism " new patent, disclose another kind of existing motor stator 90.This motor stator 90 comprises several magnetic conductive part 91, and this several magnetic conductive part 91 includes flank 911 and a beam arm 912 respectively.The flank 911 of this several magnetic conductive part 91 is respectively arranged with coil 92; Beam arm 912 two ends of this several magnetic conductive part 91 are provided with junction surface 913, mutual for this several magnetic conductive part 91 group is set as stator group mechanism by this junction surface 913.
The assembly method of the existing motor stator of aforementioned another kind 90 utilizes the mode as powder metallurgy to make this several magnetic conductive part 91 in advance; It is inferior to winding coil 92 on the flank 911 of this several magnetic conductive part 91; Finally by this junction surface 913 this several magnetic conductive part 91 must be combined with each other again and be integrated.
Generally speaking, this another kind of existing motor stator 90, before this several magnetic conductive part 91 not yet combines, namely carries out the winding operation of this coil 92, therefore the winding operation of this coil 92 can be made more unrestricted.But, though the manufacture method of this existing motor stator 90 can promote the convenience of winding operation, but still must assemble this several magnetic conductive part 91 one by one after completing winding operation, therefore, still there is the shortcomings such as the loaded down with trivial details and convenience of number of assembling steps is not good.In addition, several magnetic conductive part 91 is still included by the motor stator 90 completed manufactured by above-mentioned steps flow process, therefore, also have cost of manufacture as aforementioned existing external-rotor motor 80 high, not easily reduce axial height and run stability is not good etc. that shortcomings is still waited to improve.
