Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, a kind of motor, comprise front end housing 5, rear end cap 9, support, stator module, rotor assembly, fan blade 10 and fan housing 11, rotor assembly has main shaft 1 and is fitted in the internal rotor 3 at main shaft 1 middle part, stator module comprises the stator support that is connected with support 6, the independent iron core unit 7 of the many group same structure of circumference uniform distribution on stator support, every group of independence iron core unit 7 comprises iron core piece 13 that is connected with stator support and the electromagnetism winding coil 12 that is around on the iron core piece 13, organizes the iron core piece 13 of independent iron core unit 7 and the outer round surface formation air gap of internal rotor 3 more.Internal rotor 3 adopts the dual permanent-magnet rotor, and front end housing 5 is installed in the left side of support 6, and stator support is fitted in the inner chamber middle part of support 6, and rear end cap 9 is installed in support 6 right sides, and main shaft 1 is installed in the interior cover of front end housing 5 and rear end cap 9 centre bore inner bearings 2; Fan blade 10 is contained in the right-hand member of main shaft 1, and fan housing 11 is fixed on the outer end of rear end cap 9.Bearing 2 is installed in respectively in the centre bore of front end housing 5 and rear end cap 9, stator support comprises non-magnet material dish type main support 4 and non-magnet material dish type assistant support 8, non-magnet material dish type main support 4 and non-magnet material dish type assistant support 8 all have the rack groove 16 of circumference uniform distribution, the central authorities of iron core piece 13 bottoms of every group of independence iron core unit are provided with U-lag 14, electromagnetism winding coil 12 is embedded in the U-lag 14 of iron core piece 13, the both sides of iron core piece 13 have raised line 15, the both sides raised line 15 of iron core piece 13 adapts with the rack groove 16 of non-magnet material dish type main support 4 and non-magnet material dish type assistant support 8 respectively, and the iron core piece 13 of every group of independence iron core unit all is riveted between non-magnet material dish type main support 4 and the non-magnet material dish type assistant support 8.
