Description

Motor stator

Technical field

The utility model is about a kind of motor stator, especially a kind of made motor stator of manufacturing process step of simplifying.

Background technology

Common on the market motor stator roughly can be divided into the stator of external-rotor motor and the stator of inner rotor motor at present; Wherein the manufacturing process of the stator of the stator of inner rotor motor and external-rotor motor and structure thereof are formed roughly the samely, therefore, below are example with the stator of inner rotor motor, and the manufacture method and the structure thereof that have motor stator now be describeds.

Please refer to shown in Figure 1ly, the step of manufacturing of existing motor stator 80 includes: in advance with several silicon steel sheets 81 of impact style moulding, and these several silicon steel sheets 81 are piled up mutually be combined as a whole; Secondly respectively at the two ends of these several silicon steel sheets 81 each in conjunction with insulating case 82 on one and insulating case 83 once; Prepare a coil groups 84 at last, this coil groups 84 is reeled simultaneously be incorporated into these several silicon steel sheets 81 again, the predetermined position of insulating case 82 and this time insulating case 83 on this, finish a motor stator 80 with manufacturing.

Generally speaking, the manufacture method of existing motor stator 80 still has many shortcomings as described below:

1, manufacturing step complexity: existing motor stator 80 during fabrication, must mold this several silicon steel sheets 81 one by one with impact style in advance, and it is actual when carrying out assembling operation, more necessary with after respectively this silicon steel sheet 81 mutually combines by stack manner, to go up insulating case 82 and this time insulating case 83 again and be incorporated into the respectively two ends of this silicon steel sheet 81 respectively, can carry out the winding operation of this coil groups 84 at last; Generally speaking, therefore the suitable very complicated of step of manufacturing flow process of existing motor stator 80, causes cost of manufacture raising and assembling convenience not good.

2, the bad of the finished product after the manufacturing: because existing motor stator 80 is finished this several silicon steel sheets 81, last insulating case 82 and down insulating case 83 in conjunction with after the operation, can carry out the winding operation of this coil groups 84, be subject to this several silicon steel sheets 81, last insulating case 82 and the restriction of the structure space of insulating case 83 down, as shown in Figure 1, can't more press close to causing several coils 841 distance each other of this coil groups 84 easily, therefore, be difficult for increasing the winding turns or the line footpath of this coil groups 84, also promptly when this motor stator 80 is applied to general motor configuration, then can't effectively improve the torsion and the rotating speed of motor.

3, coiling is difficult for: especially when making the stator 80 of existing inner rotor motor, because this silicon steel sheet 81 roughly is a toroidal ring structure, this coil groups 84 then must be finished winding operation in the medial surface of this toroidal ring structure, therefore, cause winding operation inconvenience, and derive and lose time and shortcoming such as human cost, moreover, easier in the process of winding operation careless this coil groups 84 of scratch, can reduce the quality of this motor stator 80 equally.

Moreover the motor stator 80 that manufacturing is finished by the above-mentioned steps flow process is by insulating case 82 on several silicon steel sheets 81,, once insulating case 83 and a coil groups 84 are constituted, and therefore, existing motor stator 80 has many shortcomings as described below:

1, be difficult for the reduction axial height: at present common on the market motor is gradually towards microminiaturized direction research and development design, but should existing motor stator 80 still includes numerous and diverse members such as several silicon steel sheets 81 that pile up mutually and upper and lower

insulating case

82,83; Therefore, cause the axial height of this motor stator 80 to increase on the contrary, when this motor stator 80 is applied to motor configuration,, cause this motor configuration to be difficult for being designed to more compactization the overall volume and the axial height of motor configuration can't effectively be reduced.

2, run stability is not good: when this motor stator 80 is applied to motor configuration to drive rotor when rotation, because this motor stator 80 includes silicon steel sheet 81, and this rotor is provided with a permanent magnet that is staggered and is formed by the N/S utmost point, therefore, when generation between the N/S of this permanent magnet utmost point and this silicon steel sheet 81 formed magnetic pole strengths relatively moves, cogging or uneven effect promptly can take place, also promptly be commonly called as magnetic torsion phenomenon (Cogging Torque), particularly under the slower situation of the rotary speed of this rotor, more be easy to generate oscillation phenomenon.

Please refer to shown in Figure 2ly, be M248128 number " combined-stator group mechanism " novel patent of TaiWan, China, disclose another kind of existing motor stator 90.This motor stator 90 comprises several magnetic conductive parts 91, and these several magnetic conductive parts 91 include a flank 911 and a beam arm 912 respectively.Respectively be arranged with coil 92 on the flank 911 of these several magnetic conductive parts 91; Beam arm 912 two ends of these several magnetic conductive parts 91 are provided with junction surface 913, so that by this junction surface 913 these several magnetic conductive parts 91 mutual groups are set as stator group mechanism.

The assembly method of the existing motor stator 90 of aforementioned another kind is to utilize in advance to make this several magnetic conductive parts 91 as the mode of powder metallurgy; It is inferior to winding coil 92 on the flank 911 of these several magnetic conductive parts 91; Must by this junction surface 913 these several magnetic conductive parts 91 be mutually combined again at last and be one.

Generally speaking, the existing motor stator 90 of this another kind in these several magnetic conductive parts 91 as yet not in conjunction with before, promptly carry out the winding operation of this coil 92, so can make the winding operation of this coil 92 more unrestricted.Yet, though the manufacture method of this existing motor stator 90 can promote the convenience of winding operation, but after finishing winding operation, still must assemble these several magnetic conductive parts 91 one by one, therefore, still have shortcomings such as the loaded down with trivial details and convenience of number of assembling steps is not good.In addition, the motor stator 90 that manufacturing is finished by the above-mentioned steps flow process still includes several magnetic conductive parts 91, therefore, also have cost of manufacture height as aforementioned existing external-rotor motor 80, be difficult for many shortcomings such as reduction axial height and run stability be not good and still wait to improve.
