Embodiment
Primary and foremost purpose of the present invention is to provide a kind of manufacture method of new stator, also can be described as a kind of method that overcoat is set at stator module.Its scheme of taking is:
A kind of manufacture method of stator comprises following operating procedure:
S1: the enamelled wire coiling to stator core, and then is arranged lead-in wire and/or circuit board at the winding that the enamelled wire coiling forms, and be fixed with insulating tape, obtain stator module;
S2: winding plastic film 20 and so that plastic film 20 extends to respectively two outer ends of stator module 10 on the outer peripheral face of stator module 10 forms an annular plastics groove 20 ' that is wrapped in stator module 10 outer surfaces with heater heating of plastic film 20 so that plastic deformations occur plastic film 20 again;
S3: the stator module 10 that outer surface is provided with annular plastics groove 20 ' is put into mould injection moulding curing molding at the periphery of stator module formation casing.
In this application; stator module 10 to be simplified regard a hollow cylinder as; such as Fig. 1; structure shown in 2; the outer peripheral face of indication refers to the outer side surface that this hollow cylinder is axial; the width of selected plastic film 20 is greater than the axial dimension of this hollow cylinder; like this after plastic film 20 is wrapped in the outer peripheral face of stator module 10; plastic film 20 will form an extension in two outer ends of this hollow cylinder; namely such as Fig. 3; structure shown in 4; the heater heating is so that plastic film 20 produces plastic deformation; the plastic film 20 of 10 liang of outer ends of stator module shrinks and the end face of 10 liang of outer ends of stator module fits so that extend to; form the annular plastics groove 20 ' of sealing; such as Fig. 5; 6; structure shown in 7, thereby to enamelled wire; lead-in wire and circuit board form protective effect.The notch of the annular plastics groove 20 ' that forms when concrete operations can be made as the closing in shape.
Should choose the generation plastic deformation at actual mechanical process effective, the temperature of plastic deformation should be higher than the operating temperature of injection moulding curing molding when the periphery of stator module formation casing, and the plastic packaging motor after need guaranteeing simultaneously to make up runs well.Therefore, the applicant finds through long term test, and the thickness that adopts the PVC material to consist of is that plastic film 20 effects of 0.06～0.08mm are best, and the thickness 0.06～0.08mm of indication refers to the thickness of one deck plastic film 20.This kind plastic film 20 not only plastic deformation is effective, can be effectively attach mutually with the outer surface of stator module 10, and the annular plastics groove 20 ' that forms after the moulding is breakdown voltage resistant for 2500V/60S, not flicker, can effectively guarantee the safe handling of plastic packaging motor.
