Fig. 2 is the sectional view of Fig. 1.
Wherein, 1-end cap, 2-cooling liquid inlet, 3-stator core, 4-rotor, 5-cooling liquid outlet, 6-stator winding, 7-support liner, 8-sealing ring, 9-support overcoat, 10-axial notch, 11-cannelure.
Embodiment
Below in conjunction with accompanying drawing execution mode of the present utility model is described further.
Referring to Fig. 1-2, a kind of electric automobile main motor, it comprises casing, the casing two ends are provided with end cap 1, are provided with stator core 3 and rotor 4 in the casing, and described casing comprises support liner 7 and support overcoat 9, the inboard of support liner is provided with stator core, stator core is provided with stator winding 6, and the support liner outside is provided with cannelure 11, between the cannelure by axial notch 10 UNICOMs; Support overcoat bottom is provided with cooling liquid inlet 2 and cooling liquid outlet 5, axial notch on cooling liquid inlet, cooling liquid outlet and the support liner or cannelure UNICOM, and sealing ring 8 is equipped with in support liner and support overcoat junction.
The course of work of the present utility model is such: promptly automobile itself is used to cool off the cooling fluid of heat generating components such as storage battery, enter the top of the annular groove 11 arrival motors on the liner 7 from the cooling liquid inlet 2 on the support overcoat 9 by the pressurization of the pump on automobile back, converge the back and enter another annular groove by axial notch 10, flow out by cooling liquid outlet at last, in this cyclic process, take away the heat of motor stator winding 6, stator core 3 generations.
Protection range of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
