Description of the invention: [Technical field of the invention] Structure between a component and a pole piece The present invention relates to a "structure of a motor", which mainly relates to a structure between a rotor mechanism and a stator mechanism, in particular The magnetic motor in the brush motor [previous technology]. The current fans can basically be divided into two types: (1) axial fan Axial (far〇' and (2)_shooting fan (centrifugal blower) (Ce coffee - b1〇wer) Among them, the axis_fan has a lower cost, but accounts for (4). Although the above-mentioned paving fan has thinner blades, the airflow density is higher, but the cost is higher and the noise is louder. The power unit can be placed on the surface type (and (2) carbon brush motor. The structure of the towel brushless motor is: the coil is: the stator and the rotor is set with magnetic components, which is the structure of the conventional carbon brush. The side is reversed. The rhyme rides on the rotor. The magnetic _ 牛, J... is on the raft, so the brushless motor does not have to be connected by the commutator and the carbon brush. Electricity and rectification, the forest needs the carbon brush of the love goods is..., month b After the power receiving coil is energized, it interacts with the magnetic field of the rotor magnetic element. Therefore, the current fan is not the axial fan or the radiating fan uses the brushless motor as the power unit. 1255605 Please refer to the first figure, which is a structure of a conventional fan. As shown, it mainly includes a rotor mechanism 11 and a stator mechanism 12', wherein the rotor mechanism u includes a driving portion 111 and a magnetic element 112' and the magnetic element The 112 series is disposed around the driving portion 111. In the preferred embodiment, the driving portion iii is bound to the fan blade 111C, the drive shaft 111d, and the hub portion 11l, and the drive shaft iiid is provided with a bearing 111e. The rafter 12 includes a pole piece 12 and a socket 123. The chip 121 is assembled on the socket (2), and the coil 122 is wound around the stator provided on the socket 123. Referring to the second figure, as shown in the figure, the holder 123 is connected to the outer frame 13 and the circuit board 123 is provided with a circuit board (2) & The magnetic f τ ο ect 112 is set in the hub of the rotating part (1), and then the bearing group The hollow chamber 123b opened on the socket 123 is finally pivoted on the stator mechanism 12 by the rotor mechanism 11, and the pole piece 2 corresponds to the magnetic element 112 without contacting 'to make the coil 122 energized and the magnetic element 112 achieves the effect of changing the phase operation. 隹The above-mentioned fan structure, because the magnetic element (1) and the pole piece 121 ^ and the arrangement of the clothes make the thickness of the hub, the wind feather industry is increasingly demanding light, Under the trend of thin, short, small and large air volume, _ the above-mentioned fan structure does have the necessity of light, thin, short and small improvement. According to this, the inventor of this case exhausted his mind to engage in the (4) Years of experience, the potential of 6 1255605 heart research, and finally successfully developed the invention of the enhancement of this function. The structure of the factory motor is actually one. [The object of the invention] The main purpose of this U is to provide a structure that can reduce the thickness of the brushless motor. The secondary purpose of this month is to provide a structure that reduces the weight of the brushless motor. ▲This 1st shape is designed to provide a structure that improves the efficiency of the brushless motor.
