The advantages that machining, therefore the upper extensive application such as motor, car wheel electromotor is controlled in (robot use).Currently, often
Centralized winding electric machine stator includes aluminum frame iron core and the terminal plate that is fixed on a shaft end of aluminum frame iron core, aluminium branch
The periphery wall of frame iron core is uniformly arranged in the circumferential direction multiple axial stator teeths, the gap shape between two neighboring stator teeth
At stator slot, insulation sleeve is equipped with around component, around component by upper insulation framework, lower insulation framework, interior insulation on each stator teeth
Paper, coil and external insulation paper composition, upper insulation framework are set to the top of stator teeth, and lower insulation framework is set to stator teeth
Bottom, interior insulation paper bag is wrapped in outside stator teeth, and coil is set around outside interior insulation paper, and external insulation paper bag is wrapped in outside coil, line
Two leads of circle are connect with terminal plate respectively by phase.The centralized winding electric machine stator of this structure has the following problems:
1) each two leads of the coil in component are directly connect with terminal plate respectively by phase, or by phase first by multiple windings
A piece lead of the coil in part, which links together, to be connected on terminal plate, regardless of which kind of mode used, all there is coil
The more random phenomenon of lead, is easy to cause the problem of puncturing between phase in this way；2) the centralization winding electric machine stator with
It is not directly connected between motor casing a little, fixation is unstable, and oscillation phenomenon is obvious.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of centralized winding electric machine stators, can effectively prevent phase
Puncture between position, and vibration can be effectively reduced.
The technical scheme of the invention to solve the technical problem is: a kind of centralization winding electric machine stator, including
Aluminum frame iron core and terminal plate are uniformly arranged in the circumferential direction multiple axial stator tooths on the periphery wall of the aluminum frame iron core
Portion, insulation sleeve is equipped with around component on the stator teeth, it is described around component by upper insulation framework, lower insulation framework, it is interior absolutely
Edge paper, coil and external insulation paper composition, the upper insulation framework are set to the top of the stator teeth, and described is lower exhausted
Edge skeleton is set to the bottom of the stator teeth, and the interior insulation paper bag is wrapped in outside the stator teeth, described
Coil is set around outside the interior insulation paper, and the external insulation paper bag is wrapped in outside the coil, it is characterised in that: around all
The periphery of the upper insulation framework is provided with an insulation annular fixing frame, is provided with three on the insulation annular fixing frame
A annular groove, a flat cable copper conductor is each provided in annular groove described in three, and the terminal plate is connected to described
It insulate on annular fixing frame, the W phase of the terminal plate, V phase, U are connected described in copper wire and three one a pair of flat cable copper conductor
It should weld, two leads of the coil are welded with flat cable copper conductor described in wherein two respectively by phase.
Be uniformly arranged in the circumferential direction on the periphery wall of the insulation annular fixing frame it is multiple be connected and fixed piece, the centralization
Winding electric machine stator is fixedly connected by the piece that is connected and fixed with motor casing.Pass through the periphery wall in insulation annular fixing frame
Upper setting is connected and fixed piece, is fixedly connected with the centralization winding electric machine stator with motor casing by being connected and fixed piece, in this way may be used
Increase torque, improves the stability maintenance of the centralization winding electric machine stator, vibration can be effectively reduced.
Compared with the prior art, the advantages of the present invention are as follows:
1) by the way that an insulation annular fixing frame is arranged around the periphery of all upper insulation frameworks, and in insulation annular fixing frame
Three annular grooves in a flat cable copper conductor is respectively set, the three of such connecting plate be connected copper wire respectively with three flat cable copper conductors
Be correspondingly connected with, and two leads of coil can be directly connect with wherein two flat cable copper conductors by phase, with this come realize coil and
The electrical connection of terminal plate, since the annular fixed mount setting that insulate is in the periphery of upper insulation framework, two leads of coil can
It is closely connect with wherein two flat cable copper conductors, the random phenomenon of two leads of coil will not be caused.
2) two leads of the coil due to each in component can closely be connect with wherein two flat cable copper conductors, because
This effectively prevents the problem of puncturing between phase.
