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

Interior insulation paper, coil and external insulation paper composition, the upper insulation framework is set to the top of the stator teeth, described
Lower insulation framework is set to the bottom of the stator teeth, and the interior insulation paper bag is wrapped in outside the stator teeth, institute
The coil stated 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
The periphery of all upper insulation frameworks is provided with an insulation annular fixing frame, is arranged on the insulation annular fixing frame
There are three annular groove, it is each provided with a flat cable copper conductor in annular groove described in three, the terminal plate is connected to institute
On the insulation annular fixing frame stated, the W phase of the terminal plate, V phase, U are connected flat cable copper conductor one described in copper wire and three
Two leads of one corresponding welding, 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 utility model are:
