The rotor housing 240 is more convenient at all times. The eye-and-see FIGS. 3 and 4 are the front view of the front view and the metal member of the second housing of the preferred embodiment of the present invention. As shown, the stator unit 230 of the present invention includes a plurality of metal members 23Q2 which are overlapped with each other and the shaft 220 passes through the center of the metal members 23〇2. Each of the metal members 23〇2 is provided with a plurality of magnetic pole portions 23022, and a plurality of magnetic pole portions 23022 are annularly distributed around the metal member 2302. The magnetic member 280 is located between the second housing 244 and the magnetic pole portion 23022. When the metal members 2302 are overlapped with each other, the plurality of magnetic pole portions 23〇22 are superposed as the magnetic pole arms 232, and the coils 234 are wound around the stacked magnetic pole arms 232. The present invention further comprises an insulating member 236. The insulating material can be made of paper or plastic, the insulating member 236 J is disposed between the adjacent magnetic pole arms 232, and the coil 234 is respectively wound around the adjacent insulating member 236'. When the coil 234 is wound around the stacked magnetic pole arm 232, the coil 234 does not contact the metal member 2302, so that short circuit can be avoided to prolong the service life of the motor structure 200. In addition, each of the magnetic pole portions 23 〇 22 includes a connecting portion 23024 and a magnetic conductive portion 23026. The connecting portion 23024 is annularly distributed on the outer edge of the metal member 2302 and is connected to the metal member 2302. The magnetic conductive portion 23026 is extended at the connection. The portion 23024 'places each of the magnetically conductive portions 23026 between the magnetic element 280 and the connecting portion 23024. The insulating member 236 is circumferentially fixed between the adjacent connecting portions 23024, and the wire 234 is wound around the connecting portion 23024' and the coil 234 is not connected to the connecting portion 23024 by the insulating member 236. The connection portion of the present invention is a long rectangle, so that the number of coils can be increased, so that the number of coils 234 is increased, thereby increasing the operating speed of the M443780. The two sides of the magnetic component 280 of the present invention are respectively a curved surface, and the magnetic component 28 is formed in a cross-sectional view, and the miscellaneous component 28 () is disposed on the second slot 244 after being fixed to the second housing 244. The inner wall. Further, the side surface of the magnetic conductive portion 23A is also a curved surface', and the magnetic conductive portion 23026 is opposite to the curved surface of the magnetic member 28''. In this way, the magnetic pattern generated by the plurality of magnetic elements 28G can be close to a sine wave, and when the rotor is in operation, the magnetic force of the magnetic conductive portion 23G26 does not have a fault phenomenon, so that the smooth operation of the rotor can be increased, and the motor structure can be increased. 2 运作 operational efficiency. In addition, the motor structure 2 of the present invention uses a high-voltage DC brushless motor, and the coil 234 in the motor structure 200 is selected to have a wire diameter ranging from 公25 mm to 〇. 29 mm between the coil 234 The number of laps is between 700 and 12 〇〇, the traditional fan is mostly the secret pressure brushless motor, the low voltage is not reached, the diameter range of the 234 selected is 0.25 cm ~ 〇 · 7 mm Between the coils, the number of turns of the coil is between 0匝300 E. The gap between the coils 234 of the magnetic poles m2 and the coils 234 is small, that is, the coil 234 has a large groove ratio, and the creation is large. The copper wire material is used less, thus saving manufacturing costs. The fan device of this creation is illustrated by a ceiling fan. This creation can also be applied to other fan devices, such as vertical fans, wall-mounted fans, etc., using different leaf assembly excitations, with the motor structure of the creation, not It is necessary to use the additional sensory benefit to use only the drive module 270 to drive the DC brushless motor structure. Although the embodiment of the present invention is disclosed as described above, it is not intended to limit the creation of the present invention, and any of the fresh-skilled artists, without departing from the spirit and scope of the supplement, will be referred to by the 12 M443780. The characteristics and quantity can be changed a little. Therefore, the scope of the application scope of this creation is subject to the definition of the application scope. month
