Manufacturing cost.
From the aspect of motor volume is reduced, insulating barrier 2 can be respectively provided with the bottom wall 11 of electric motor end cap and side wall 12, this
Sample can reduce the distance between bottom wall 11 and side wall 12 of stator winding and electric motor end cap simultaneously, make footpath of the motor along motor shaft
Reduce to the size of direction and axial direction.And the mode that insulating barrier 2 is arranged on bottom wall 11 and side wall 12 has a variety of
Selection, as shown in figure 4, can be operated using the outer shape auxiliary mould X corresponding with the interior shape of electric motor end cap,
Specifically, megohmite insulant can be first coated on auxiliary mould X, then the megohmite insulant and motor side that will be coated with auxiliary mould X
Lid contact, extruding auxiliary mould X make megohmite insulant be adhered to electric motor end cap to form insulating barrier 2, or, also can be by auxiliary mould
Preset clearance (gap can be the thickness of insulating barrier 2) assembling between X and electric motor end cap, then by megohmite insulant (such as insulating cement)
Injected from gap to form insulating barrier 2 on the bottom wall 11 of electric motor end cap and side wall 12, as shown in figure 4, the injection of megohmite insulant
Mouth Y can be the close position intersected of inclined side of side wall 12 and auxiliary mould X.It can be accelerated in motor side using auxiliary mould X
The speed of insulating barrier 2 is set simultaneously on the bottom wall 11 and side wall 12 of lid, improves operating efficiency.
It is understood that also can according to during real work to the installation requirement of motor size, in bottom wall 11 and side wall 12
One of it is upper insulating barrier is set, accordingly even when also can not quickly set insulating barrier 2 on electric motor end cap by auxiliary mould X.
The material of insulating barrier 2 has multiple choices, it is preferable that the insulating barrier 2 is by insulating cement, insulating paper and casting glue
One is formed.Wherein, insulating cement and casting glue can be arranged on electric motor end cap by auxiliary mould X mentioned above.Insulating paper
It can be directly placed on the bottom wall 11 of electric motor end cap.And preferably, the thickness T of the insulating barrier 2 is 0.5-1.0mm.
Certainly, insulating barrier 2 can be set directly on the flat interior surface of electric motor end cap, however, it is preferred that the side wall 12
And/or the groove for accommodating the insulating barrier 2 is provided with the bottom wall 11.Set groove conveniently to position, make insulating barrier 2
Set location it is more accurate.And preferably, the span of the depth of the groove is 0.5-1.5mm.Due to above
The thickness T for mentioning insulating barrier 2 can be 0.5-1.0mm, that is to say, that the span of the depth of groove is more preferably greater than insulating barrier 2
Thickness, such groove can not only play a part of positioning, as shown in figure 5, the depth in groove is identical with the thickness of insulating barrier 2
When, the inwall of electric motor end cap is more smooth, convenient to install stator module.
The utility model second aspect provides a kind of motor, what the motor stretched out including casing 10, from the casing 10
Motor shaft 20, rotor assembly and stator module 30 in the casing 10 on the motor shaft 20, the stator pack
Part 30 is set around the rotor assembly, and the casing 10 includes two above-mentioned electric motor end caps, and two electric motor end caps
Connected by the flange 13.Because the motor employs above-mentioned electric motor end cap, make the stator winding and electric motor end cap of motor
On insulating barrier can contact, that is to say, that without reserved electric clearance and creep age distance between machine winding and electric motor end cap, make
With more securely and reliably, manufacture and assembly difficulty are on the one hand reduced, on the other hand due to reducing stator winding and motor side
The distance between the bottom wall of lid and/or side wall, it can also reduce the volume of motor and reduce manufacturing cost.
Because motor inevitably produces vibrations in normal work, therefore, between two electric motor end caps
Connection must be reliably secure, it is preferable that is provided with through hole on the flange 13, fastener is by the through hole by two electricity
