Detailed description of the invention
The specific implementation method of the present invention is as follows:
Motor stator winding is the major heat producing components in stator running, but stator
Good heat dissipation bad influence the radiating effect that motor is overall, because the heat of rotor is also
Major part needs to be dispersed by motor stator transmission, so, the radiating effect of motor stator
Very big for motor integral heat sink and power influential effect, for improving dissipating of motor stator
The radiating efficiency of the thermal efficiency, particularly stator winding, the present invention proposes the double of a kind of stator
Winding electric machine stator structure and processing technology thereof, illustrate the present invention below in conjunction with the accompanying drawings

It is illustrated in figure 1 the partial schematic diagram of traditional double winding electric machine stator structure, described
First stator core 1 and the second stator core 2 are overrided to form by punching, yet with folded
The precision of pressure limits, and between each punching, existence laminates irregular, and this results in described first
Air void is left between stator core 1 and described first insulation framework 3, described second
Also air void, Er Qieyou is left between stator core 2 and described second insulation framework 4
Will not fit completely during coiling institute in described first coil 5 and the second coil 6
State the first insulation framework 3 and the second insulation framework 4, the most described first insulation framework 3 with
Air void, described second insulation framework 4 and institute can be had between described first coil 5
