Embodiment
Refer to Fig. 2, a better embodiment of disk type electric machine stator of the present invention is installed in the casing of a motor.Stator comprises some potsherds 1 in order to heat radiation and some coils 3 in order to conduction.The inside and outside both sides of potsherd 1 are blocked respectively in the inner ring of coil 3 and outer ring.Lead loop 3 is along the radial distribution of stator.The inner ring of wire is usingd epoxy resin as insulating body.
The internal edge of potsherd 1 is connected with coil 3, to derive the heat producing when coil 3 is worked.Potsherd 1 outer end stretches out the part of coil 3 and the annulus 2 of a grooved faces is connected.(around outer ring, forming an annulus), thus area of dissipation increased.One cooling system can be connected with metal ring 2.Cooling system can be the pipeline that liquid cools is used, and can be also the metalwork of heat conduction use.
In another better embodiment of disk type electric machine stator of the present invention, the one side of potsherd 1 press-fits heat radiating metal annulus 2, and another side is connected to the casing of motor by flexible material, in order to reduce vibratory impulse.Flexible material is rubber.
In another better embodiment of disk type electric machine stator of the present invention, heat radiating metal annulus 2 has hollow structure, and the inside is filled with coolant, to increase heat-sinking capability.
A disk type electric machine stator heat dissipating method, comprises the following steps: stator is provided with some potsherds 1 in order to heat radiation and some coils 3 in order to conduction.According to the overall dimension of the good thermal conductive ceramic plate 1 of stator disc size design; Copper conductor is turned on mould to required coil shape; Inner ring with epoxy resin cure coil 3; Potsherd 1 is inserted to coil 3 by outer ring, and the inner edge of potsherd 1 snaps into epoxy resin ring, and outside coordinates with metal ring 2, is assembled into stator disc.
The outside of potsherd 1 is waled to increase area of dissipation in coil 3 outer rings.Finally, stator is installed on the casing of a motor.
The present invention uses thermal conductive ceramic plate substituted epoxy resin, forms a ceramic stator dish, then copper conductor is stuck on potsherd.Simple, the convenient production in enormous quantities in enormous quantities of better embodiment technique of disk type electric machine stator of the present invention.The technique that potsherd 1 is assembled into stator disc is very simple, more simply too much than then solidifying with epoxy gluing, and potsherd can mass production, steady quality, high conformity.
The better embodiment of disk type electric machine stator of the present invention has good thermal conductivity.Thermal conductive ceramic is easy to reach the thermal conductivity of 20w/ (m*k), 200w/ (m*k) even, and epoxy resin only has the thermal conductivity of 0.2w/ (m*k) left and right, after adding heat conduction powder, also only has the thermal conductivity of 2w/ (m*k) left and right.So ceramic stator dish can transmit out by the heat in stator disc very soon.
