Description
Technical field
The utility model is related to motor with cup rotor technical fields, more particularly, to a kind of end cap and motor with cup rotor.
Background technology
Motor with cup rotor is called shadedpole motor, is one kind in single-phase AC motor, the casting of generally use cage modle skewed slot
Aluminium rotor.It is divided into according to the difference of stator contour structures as salient pole type shaded-pole motor and hidden pole type shaded-pole motor.
The stator core shape of salient pole type shaded-pole motor is rectangular, rectangle or circular field frame, and magnetic pole protrudes, often
There are one or more short-circuit copper rings to help out, i.e. split-pole winding on a magnetic pole.Concentratred winding conduct on magnet limbs
Main winding.
The stator core of hidden pole type shaded-pole motor is identical as the iron core of common single-phase motor, and stator winding, which uses, to be divided
Cloth winding, main winding are distributed in stator slot, and split-pole winding does not have to short-circuit copper ring, but be coiled into thicker enameled wire be distributed around
Group (voluntarily short-circuit after series connection) is inlaid in stator slot (about the 1/3 of total slot number), plays assisted group.Main winding and split-pole
Winding is in space at a distance of certain angle.After the main winding of shaded-pole motor is powered, split-pole winding also will produce induced current,
Magnetic pole of the stator is set to be rotated to the direction of quilt cover part with non-cover portion point by the magnetic flux of split-pole winding house portions.
The advantages of shadedpole motor is exactly simple in structure, does not have to separately add winding and capacitor, the disadvantage is that efficiency is low, slippage
Greatly.The draining pump that air-conditioning coil insertion device uses is typical motor with cup rotor, and fraction defective is low, and generic failure is that motor is dirty stifled.
In the prior art, motor side is stamped aluminium and suppresses, and during use, finds poor sealing, damping performance
It is bad.

Property body, the rubber of this namely traditional sense.
The definition of thermoplastic elastomer (TPE) is：Caoutchouc elasticity is shown at normal temperatures, is capable of the high score of plasticizing forming at high temperature
Sub- material.Therefore, this kind of polymer has certain features of thermoplastic elastomer and thermoplastic concurrently.Thermoplastic elastomer macromolecule
The basic structure feature of chain is it while connecting or being grafted the different plastics section (hard section) of certain chemical compositions and rubber segments are (soft
Section).Active force between hard section is enough to be aggregated into microcell (such as vitrifying microcell or crystalline domains), forms intermolecular physics and " hands over
Connection ".Soft segment is then the larger high-end property segment of own rotatory power.
Thermoplastic elastomer (TPE) TPE/TPR, also known as artificial rubber or synthetic rubber.Its product had both had the cross-linking vulcanized rubber of tradition
The high resiliency of glue, ageing-resistant, the every excellent properties of oil resistivity, while, processing method easy to process but also with common plastics is wide
Feature.The production of the processing methods such as injection molding, extrusion, blowing, 100% direct secondary use after mouth of a river corner crushes can be used.Both simple
Change process, and reduce processing cost, therefore thermoplastic elastomer (TPE) TPE/TPR materials have become the newest of the traditional rubber of substitution
Material, environmentally friendly, nontoxic, comfortable feel, exquisite appearance, makes product have more intention.Therefore it is also more hommization, a Gao Pin
The novel synthetic material and globalization standard environment-friendly materials of position.The thermoplastics processing equipment and technique of available standards
It is processed molding, such as squeezes out, injection, be blow molded.It is not required to vulcanize, production rubber product can be prepared, reduce vulcanization process, save
Investment, low energy consumption, and the simple for process, process-cycle shortens, and production efficiency improves, and processing charges is low.
In the alternative of the present embodiment, washer 2 is rubber material.
Rubber refers to the high elastic polymer material for having reversible deformation, high resilience at room temperature, in the external force of very little
Effect is lower to be generated compared with large deformation, and resilient after external force is removed.
The washer 2 of rubber material has certain self-tightening effect, and sealing effect is than more preferable, pressing force smaller.
