Abstract
This invention relates to dish watching machine motor wire protection structure composed of glass fiber lead wire to protect wire from motor shell, wherein, lead wire is covered on lead wire from motor shell and stator coil set through motor shell extending outside shell with lead part at 20mm.
Description
Technical field
The present invention relates to motor, particularly relate to the motor windings lead-in wire.
Background technology
Motor is the device that converts electrical energy into mechanical energy, mainly is to provide the rotary machine energy by the parts that rotate under the effect of current field.Therefore, motor becomes many household electrical appliance, as the vitals of air conditioner, washing machine, dishwasher etc.In air conditioner, motor is that the power of cooling cycle system compressor operation and the running of air circulation system blowing fan provides the source.In washing machine, driven by motor cylinder or impeller rotate, and realize washing, rinsing and the dehydration of clothing.In dishwasher, the driven by motor pump operation ejects water on bowl tool, realizes the cleaning to the bowl tool.
In general, motor is made up of stator and rotor two parts, and stator and rotor are made of the iron core that silicon steel plate stacking forms respectively.It is cylindric that stator is, and rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the stator cylinder cavity, has the space to be separated by between stator and rotor.The winding that the enamelled wire coiled is arranged on the stator, stator winding is connected with external power, and stator produced magnetic field when source current passed through outside.When rotor has electric current to pass through, interact, produce electromagnetic torque and make rotor rotation with stator field.
The device that the dishwasher constant power is slightly little adopts monophase machine mostly.Be not with the enamelled wire winding on the monophase machine rotor, the electric current in the rotor is not supplied with by external power, but induce by stator field.Induced current and former magnetic field interaction produce electromagnetic torque and make rotor rotation.
Fig. 1 shows the profile of the dish-washing machine motor of prior art.As shown in Figure 1, motor is made up of stator 1 and rotor 2, and stator 1 is cylindric, and rotor 2 is cylindric, and 2 of stator 1 and rotors have air gap 3 to be separated by.The winding 4 that the enamelled wire coiled is arranged on the stator 1, stator winding 4 is connected by the outer brush copper sheet 6 of lead-in wire 5 and electric machine casing, and brush copper sheet 6 is connected with external power by commutator again.Draw from motor stator winding 4 for protection lead-in wire 5 and not to be damaged, pilot protection structure is set at the place of drawing of lead-in wire 5.Pilot protection structure comprises lead wire sheath 7 and fairlead 8.Fairlead 8 is a fiberglass products, wraps in the periphery of lead-in wire 5, places the junction of enamelled wire on electric machine casing lead 5 and the stator winding 4.Lead wire sheath 7 is made of rubber, wraps in the outside of fairlead 8 and lead-in wire 5, places in the electric machine casing outside and passes electric machine casing.
But the set lead wire sheath of the motor pilot protection structure for dish-washing machine of above-mentioned prior art is made of rubber, contains polluter, does not meet requirement on environmental protection, and being provided with of lead wire sheath increased material consumption.Therefore, the improvement of pilot protection structure becomes one of the content of the above-mentioned dish-washing machine motor design of prior art.
Summary of the invention
For overcoming the existing problem of above-mentioned motor pilot protection structure for dish-washing machine of prior art; the present invention has released improved motor pilot protection structure for dish-washing machine; by cancellation rubber lead wire sheath and prolongation fairlead, reduce material consumption and meet requirement on environmental protection to reach.
Motor pilot protection structure for dish-washing machine involved in the present invention is made of fairlead, and fairlead protection lead-in wire is drawn from electric machine casing and is not damaged.Fairlead is a fiberglass products, wraps in the outside of lead-in wire, passes electric machine casing from the junction of electric machine casing lead and stator winding enamelled wire and extends to hull outside.
Because motor pilot protection structure for dish-washing machine involved in the present invention is made of the fairlead of fiberglass products, cancels the former rubber lead wire sheath that contains polluter, meets requirement on environmental protection, and, receive the effect that reduces material consumption.

Embodiment
Existing accompanying drawings specific embodiments of the invention.
Fig. 2 shows the cross-section structure of dish-washing machine motor of the present invention.As shown in Figure 2, motor is made up of stator 1 and rotor 2, and stator 1 is cylindric, and rotor 2 is cylindric, and 2 of stator 1 and rotors have air gap 3 to be separated by.The winding 4 that the enamelled wire coiled is arranged on the stator 1, stator winding 4 is connected by the outer brush copper sheet 6 of lead-in wire 5 and electric machine casing, and brush copper sheet 6 is connected with external power by commutator again.Draw from motor stator winding 4 for protection lead-in wire 5 and not to be damaged the leaded pipe 8 in outside of lead-in wire 5.Fairlead 8 is a fiberglass products, wraps in the outside of lead-in wire 5, passes electric machine casing from electric machine casing lead 5 with the junction of the enamelled wire of stator winding 4 and extends to hull outside.Fairlead 8 is at the long 20mm of extension in the electric machine casing outside.
Claims (3)
