The technical solution of the utility model is:
A kind of electric machine stand, this electric machine stand comprises support shell, axial support plate, connecting plate radially, support shell is the splicing construction of exterior panel, the cross section of support shell is polygon, axial support plate is connected with support shell, the every exterior panel inner side that forms support shell arranges axial support plate, and the stator core that is arranged in electric machine stand is supported by axial support plate; The axial support plate being evenly arranged and the exterior panel at its place are orthogonal, and the axis of axial support plate is by the center of circle of integrated motor stand structure; Between adjacent exterior panel and adjacent axial support plate, connect by connecting plate radially.
Described electric machine stand, axial support plate extends axially along frame shell inner side, and the supporting surface of axial support plate is on same cylinder.
Described electric machine stand, stator core is axially contacting completely with axial support plate, and axial support plate length is greater than stator core length.
Described electric machine stand, radially connecting plate is spaced apart vertically, and radially connecting plate internal diameter is greater than frame diameter.
Described electric machine stand, support shell is the splicing construction of six or eight exterior panels, the cross section of support shell is regular hexagon or octagon.
Described electric machine stand, is welding structure between exterior panel, every block of exterior panel inner side welding axial support plate.
Described electric machine stand, between adjacent exterior panel and adjacent axial support plate, by radially connecting plate welding.
Described electric machine stand, the stator core of electric machine stand and different length adapts, and axial support plate length is determined by the stator core of growing most.
Advantage of the present utility model and beneficial effect are:
1, the utility model, by axial support plate is set, supports continuously thereby realized axial contact, and support stiffness is good, under electric machine operation state, is difficult for deformation.
2, the utility model is simple in structure, and regular shape is easy to welding.
3, the structure-improved that adopts the utility model electric machine stand, the stator core that external diameter is identical, length is different can be used same electric machine stand, has simplified design and manufacture work flow.
4, the utility model space compactness, reduces motor volume, reduces plate wastage, cost-saving.
