Stator includes stator unit and the plastic packaging layer that is wrapped in outside stator unit, and the outer wall of plastic packaging stator is equipped with terminal clamp, rotor
Centre be equipped with armature spindle.
During the plastic packaging of stator unit, to enable the lower end surface of stator unit to be covered by plastic packaging layer, on mold cores
Equipped with step, sink after preventing stator unit to be put into mold, so there is a circle positioning step plastic packaging layer on the inner wall of plastic packaging stator.
Since step positions, the plastic packaging layer of the positioning step of plastic packaging stator is relatively thin, and when assembly is put into rotor, rotor is easy to scrape
Plastic packaging at broken step generates noise, and rotor and modeling to generate short grained plastic packaging particle when operating motor
A possibility that contact surface of sealing is larger, scratches plastic packaging is larger, so that need often to clear up the plastic packaging particle fallen, and after clearing up
Insulating layer on plastic packaging stator inner wall is destroyed, and needs to increase equipment and cost of labor to the inner wall japanning of plastic packaging stator.
Summary of the invention
The utility model mainly solves technical problem present in the above-mentioned prior art, provides one kind and exempts to clear up low noise
Plastic packaging motor.
Above technical problems of the utility model are mainly solved by the following technical scheme: one kind exempt to clear up it is low
The plastic packaging motor of noise, including plastic packaging stator and the rotor being mounted in plastic packaging stator, the centre of the rotor is equipped with rotor
Axis, the armature spindle and rotor are interference fitted, and the middle part of the plastic packaging stator is equipped with the cavity for accommodating rotor, the plastic packaging stator
Outer wall be equipped with terminal clamp, the plastic packaging stator includes end cap, stator unit and plastic packaging layer, and the plastic packaging layer is by end cap and fixed
Subelement is wrapped to form an entirety, and the end cap is equipped with axis hole, and the left end of the plastic packaging layer is equipped with and coaxial convex of end cap
Platform, boss envelope end cap, and the boss in a ring, is equipped with transition bench between the boss and plastic packaging layer, stator unit it is upper
End is evenly equipped with several locating slots on the inner wall of the plastic packaging layer, and the section of locating slot is trapezoidal, and the stator unit includes fixed
Sub- iron core, the stator core include ring-shaped yoke portion and teeth portion, are equipped with insulation protective board, the teeth portion between adjacent two teeth portion
On be wound with coil windings.
Mold cores corresponding with above-mentioned plastic packaging motor include end cap mounting portion and stator unit mounting portion, the stator
Several positioning jacking blocks are evenly equipped on the outer wall of unit mounting portion bottom, the section of the positioning jacking block is at trapezoidal, the positioning top
Block and the locating slot match.When plastic packaging, stator unit is covered on stator unit mounting portion, positioning jacking block withstands stator list
Member prevents stator unit from sinking, and end cap is placed on end cap mounting portion, and mold cores are then put into plastic packaging machine and carry out plastic packaging.
When the utility model has the advantages that stator unit plastic packaging, original step positioning is changed to jacking block positioning,
To make the positioning step on plastic packaging stator become locating slot, reduce the contact area of rotor and plastic packaging layer, rotor scratches modeling
A possibility that sealing, substantially reduces, and reduces a possibility that generating noise, while also reducing maintenance cost；Using end cap and stator
Unit integral structure, concentricity are guaranteed, the leakproofness of motor is strengthened, and are improved motor noise, and easy to assembly, are effectively mentioned
High efficiency；Equipped with the boss for enveloping end cap, the survivability of end cap is improved, improves the safety of motor；Coil
It is equipped with insulation protective board between winding, protects coil windings, it is difficult to be reduced manufacture by blastic deformation for coil windings when preventing plastic packaging
Degree.
