Movable vane wheel and rotor assembly are connected as avoiding and determine impeller and wipe mutually, so needing to pave with pad and be supported on bearing with axle sleeve, and with nut locking, and need between support and casing to be screwed.Because movable vane takes turns high speed rotating, so material is required to be the aluminum alloy materials that lightweight intensity is high, and determine impeller because of volume big, it is necessary to using PA66 injection moulding, matter is soft, it is therefore desirable to is connected with support and fixes, and causes operation various.
Summary of the invention
The present invention is various in order to solve existing motor component, and assembly process is complicated, affects the problem that the factor of its stability is various, it is provided that a kind of integral type that is equipped with determines a kind of New-type electric machine of impeller assembly.
In order to solve above-mentioned technical problem, the present invention provides a kind of New-type electric machine, including casing, rotor assembly, stator module, and determine impeller, movable vane wheel and fan housing, casing is overlapped even stator assembly and rotor assembly successively, determine impeller and include blade and bearing chamber, the axle sleeve joint bearing of rotor assembly, bearing is placed directly in bearing chamber, bearing outer face abuts axle sleeve, axle sleeve abuts movable vane axle hole limit, determine impeller, movable vane wheel and axle sleeve all axles centered by axle, it is coaxially disposed, axle head is sequentially connected with pad and lock nut near movable vane wheel, fan housing cover cap determines impeller and movable vane wheel, buckle with casing, determine impeller blade inner face and abut casing, outer face abuts fan housing inner face.
Further, determine impeller to be formed in one structure.
Further, determining impeller be material is BMC material.
Further, New-type electric machine includes end plate, diverter, insulating paper.
Further, New-type electric machine includes terminal stud.
Compared with prior art, the beneficial effects of the present invention is: case component overlaps even stator assembly and rotor assembly successively, determine impeller and include blade and bearing chamber, the axle sleeve joint bearing of rotor assembly, bearing is placed directly in bearing chamber, bearing outer face abuts axle sleeve, axle sleeve abuts movable vane axle hole limit, determine impeller, movable vane wheel and axle sleeve all axles centered by axle, it is coaxially disposed, axle head is sequentially connected with pad and lock nut near movable vane wheel, fan housing cover cap determines impeller and movable vane wheel, buckle with casing, determine impeller blade inner face and abut casing, outer face abuts fan housing inner face.Above-mentioned electric machine structure eliminates support member support, the rubber sheet gasket playing cushioning effect and various connecting bolt, the parts making motor simplify, installation step simplifies, therefore the factor affecting its stability decreases, improve the work efficiency of motor, reducing noise, new construction motor eliminates support member support simultaneously, also refer to the guide effect determining impeller to input radiation air.
