Detailed description of the invention
Embodiment, see shown in Fig. 1 and Fig. 2: be easy to the permagnetic synchronous motor of heat radiation, including housing 10, the axial line position of the inner chamber of this housing 10 is provided with rotating shaft 20, and the inner chamber of this housing 10 is provided with stator 30, this stator 30 includes the permanent magnet 31 of even number strip, and the trend of those permanent magnets 31 is same as the axial line of this housing 10, this rotating shaft 20 is provided with rotor 40, is provided with outer bearing 21 between both ends and this housing 10 of this rotating shaft 20.
Further saying, this permagnetic synchronous motor being easy to heat radiation also includes the first cooling tube the 50, second cooling tube 60 and radiating tube 70 prepared by stainless steel material. Meanwhile, this rotating shaft 20 is prepared for hollow pipe, and this first cooling tube 50 two ends of traverse and this first cooling tube 50 from the inner chamber of this rotating shaft 20 are respectively communicated with the two ends of this radiating tube 70. In order to not affect the rotation of rotating shaft 20, between this first cooling tube 50 and inner chamber of this rotating shaft 20, it is provided with inner bearing 51. Having gap between adjacent permanent magnet 31, the second cooling tube 60 two ends of traverse and the second cooling tube 60 from the gap between adjacent permanent magnet 31 are respectively communicated with the two ends of this radiating tube 70. This radiating tube 70 is positioned at the outside of this housing 10, and this radiating tube 70 is welded with some fin 71. Between the fin 71 that those fin 71 are preferably mutually parallel and adjacent, there is certain spacing. It is filled with coolant in this first cooling tube 50, second cooling tube 60 and radiating tube 70. Coolant can adopt common automotive antifreezing liquid, in some cases, pure water also can be adopted as coolant. Preferably, radiating tube 70 is furnished with circulating pump 72. So, after coolant circulation, after flowing through the first cooling tube 50 and the second cooling tube 60, take away the heat in this housing 10 respectively in a large number, make this motor have splendid radiating effect.
Continue to optimize, in order to not affect the layout of the first cooling tube 50, one end of this rotating shaft 20 is fixed with the first gear 81, the end of this housing 10 is installed with a universal driving shaft 90, one end of this universal driving shaft 90 is fixed with the second gear 82, the other end is stretched outside this housing 10, and this first gear 81 and this second gear 82 engage. So, the moment of torsion of this rotating shaft 20, after the transmission of the first gear 81 and the second gear 82, spreads out of from this universal driving shaft 90. Obviously, the axial line of this universal driving shaft 90 and this rotating shaft 20 is inevitable misaligned.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
