Abstract
The utility model relates to technical field of motors, particularly a kind of motor with assembled stator, comprise motor housing and be arranged on the stator core in motor housing, stator core is mutually assembled by stator core piece, there is the one or more locked groove extended along stator core piece length direction outside the yoke portion of stator core piece, the inwall of motor housing has the protruding lock tooth coordinating snapping with locked groove, and lock tooth comprises lock head and the connecting portion being connected lock head and motor housing.The beneficial effects of the utility model are: whole electric machine structure is firm, and stator core is reliably assembled, not yielding, and assembling is simple.
Description
Technical field
The utility model relates to technical field of motors, particularly a kind of motor with assembled stator.
Background technology
At present, the whole circular configuration that the punching of the stator core of alternating-current permanent-magnet servo motor adopts stamping-out shaping substantially, the stock utilization of silicon steel sheet is extremely low, if disregard the recycling counting rotor punching in, the utilance of usual punching stator punching is generally 30 ~ 40%, and needing to reserve the position that coiling line mouth passes through when coiling, the distance of line parlor is comparatively large, there is the problem that copper factor is low.For overcoming the problems referred to above, there is the assembled stator core structure of alternating-current permanent-magnet servo motor, assembled stator iron core is spliced into a full circle shape by multiple stator core piece, projection and groove is all offered in the side, yoke portion of stator core piece, preventing from misplacing when splicing, also needing clamp ring on cover outward at assembled stator iron core.There is complex structure in existing this assembled stator core structure, needs the defect of special splicing frock.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of motor with assembled stator, simplifies assembling difficulty, improves structural reliability.
The utility model solves the technical scheme that its technical problem adopts: a kind of motor with assembled stator, comprise motor housing and be arranged on the stator core in motor housing, stator core is assembled by stator core piece, there is the one or more locked groove extended along stator core piece length direction outside the yoke portion of stator core piece, the inwall of motor housing has the protruding lock tooth coordinating snapping with locked groove, lock tooth comprises lock head and the connecting portion being connected lock head and motor housing, the lock head of lock tooth embeds the locked groove of stator core piece, stator core piece is positioned.
Further restriction, the cross sectional shape of lock head is trapezoidal.
Further restriction, the aluminium section bar that motor housing and lock tooth are formed in one.
The beneficial effects of the utility model are: whole electric machine structure is firm, and stator core is reliably assembled, not yielding, and assembling is simple.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. motor housing, 1-1. locks tooth, 1-1-1. lock head, 1-1-2. connecting portion, 2. stator core piece, 2-1. locked groove.
Embodiment
As shown in Figure 1, a kind of motor with assembled stator, the stator core comprising motor housing 1 and be arranged in motor housing 1, stator core is assembled by stator core piece 2, there is the one or more locked groove 2-1 extended along stator core piece 2 length direction outside the yoke portion of stator core piece 2, the inwall of motor housing 1 has the protruding lock tooth 1-1 coordinating snapping with locked groove 2-1, lock tooth 1-1 comprises lock head 1-1-1 and the connecting portion 1-1-2 being connected lock head 1-1-1 and motor housing 1, the lock head 1-1-1 of lock tooth 1-1 embeds the locked groove 2-1 of stator core piece 2, stator core piece 2 is positioned, make the stator core that the assembled formation of stator core piece 2 is complete.
The cross sectional shape of lock head 1-1-1 is trapezoidal.
The aluminium section bar that motor housing 1 and lock tooth 1-1 are formed in one.
