Description
Technical field
The invention relates to a kind of Brushless DC motor and stator thereof, especially a kind of stator that omits the traditional silicon steel disc, and Brushless DC motor with this stator.
Background technology
Common on the market Brushless DC motor roughly can be divided into outer rotor-type motor and inner rotor type motor at present.Wherein external-rotor motor has simple in structure, characteristic such as thermal diffusivity is good and price is comparatively cheap usually; Inner rotor motor then has characteristics such as rotational stabilization is good.
Please refer to shown in Figure 1ly, existing external-rotor motor 8 roughly comprises a pedestal 81, a stator 82 and a rotor 83.This pedestal 81 has a central siphon 811; This stator 82 is incorporated into the outer peripheral face of this central siphon 811; This rotor 83 is provided with a permanent magnet 831, and this rotor 83 is rotatably in conjunction with this central siphon 811.Whereby, can produce the effect of magnetic interlinkage between this stator 82 and this permanent magnet 831, so that drive this rotor 83 rotation runnings.
In other words, please cooperate with reference to shown in Figure 2, the stator 82 of existing external-rotor motor 8 is made up of several silicon steel sheets 821, last insulating case 822, following insulating case 823 and a coil groups 824.These several silicon steel sheets 821 pile up mutually and are combined as a whole; Upward insulating case 822 and this time insulating case 823 are incorporated into the two ends of these several silicon steel sheets 821 respectively; This coil groups 824 reels simultaneously and is incorporated into these several silicon steel sheets 821, the predetermined position of insulating case 822 and this time insulating case 823 on this.
Generally speaking, existing external-rotor motor 8 and stator 82 thereof still have problems as described below when reality is used:
1, the high and assembling inconvenience of cost of manufacture: respectively this silicon steel sheet 821 is made moulding with impact style, and it is actual when carrying out assembling operation, more necessary earlier with after respectively this silicon steel sheet 821 mutually combines by stack manner, to go up insulating case 822 and this time insulating case 823 again and be incorporated into the respectively two ends of this silicon steel sheet 821 respectively, so can carry out the winding operation of follow-up this coil groups 824; Generally speaking, the member of existing stator 82 is quite various and structure is too complicated, therefore, causes the inconvenience that cost of manufacture is higher and assemble.
2, be difficult for the reduction axial height: at present common on the market motor is gradually towards microminiaturized direction research and development design, but aforementioned existing stator 82 still includes numerous and diverse members such as several silicon steel sheets 821 that pile up mutually and upper and lower insulating case 822,823; Therefore, cause the axial height of this stator 82 to increase on the contrary, when this stator 82 is applied to this external-rotor motor 8,, cause this external-rotor motor 8 can't be designed to more compactization with the overall volume and the axial height of this external-rotor motor 8 can't effectively be reduced.
3, run stability is not good: because this stator 82 includes silicon steel sheet 821, and the permanent magnet 831 of this rotor 83 is staggered by the N/S utmost point and forms, when generation between the N/S of this permanent magnet 831 utmost point and this silicon steel sheet 821 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 83, more be easy to generate oscillation phenomenon.
Please refer to shown in Figure 3ly, existing 9 of inner rotor motors roughly comprise a motor shell 91, a stator 92, a rotor 93 and a permanent magnet 94.This motor shell 91 is a hollow housing; This stator is installed in this motor shell 91 inside; This rotor 93 has a rotation axis 931, these rotation axis 931 rotatable this motor shell 91 inside that are incorporated into; This permanent magnet 94 is in conjunction with this rotation axis 931 and be positioned at this stator 92 inside.Whereby, can produce the effect of magnetic interlinkage between this stator 92 and this permanent magnet 94, so that drive this rotor 93 rotation runnings.
More in detail, please cooperate with reference to shown in Figure 4, the stator 92 of existing inner rotor motor 9 is made up of several silicon steel sheets 921, last insulating case 922, following insulating case 923 and a coil groups 924 equally.The stator 92 of this inner rotor motor 9 is formed roughly the same with the structure of the stator 82 of before taking off external-rotor motor 8; Therefore, the existing inner rotor motor 9 with this stator 92 still has cost of manufacture height as aforementioned existing external-rotor motor 8, assembling inconvenience, is difficult for problems such as reduction axial height and run stability be not good when reality is used.
