Description
Technical field
The utility model relates to a kind of washing machine drainage pump motor, particularly a kind of drainage pump of washing machine electric machine with aluminium winding.
Background technology
Existing washing machine drainage pump motor adopts the copper enamelled wire as excitation winding usually, but along with the rising steadily of the in short supply day by day and copper valency of copper resource in recent years, for reducing production costs, has aluminium enamel-covered wire to replace the trend of copper enamelled wire gradually.Aluminium enamel-covered wire because self, moist or contain in the air ambient of acid and alkali substance and be corroded easily and oxidation, particularly aluminium enamel-covered wire and inserted sheet tie point with easy especially oxidation after air contacts.When being connected with inserted sheet because of aluminium enamel-covered wire, very easily forming with aluminium under the effect of the contact-making surface of these two kinds of metals with the cleaning solution in the washing machine environment and airborne other material is negative pole, copper is anodal primary cell, be that the exposed tie point of aluminium enamel-covered wire produces galvano-cautery, cause copper aluminium junction resistance to increase.The thermal coefficient of expansion gap of copper aluminium is very big in addition, in use through behind repeatedly cold (ambient temperature) heat (energising heat production temperature) circulation impact, thereby making tie point produce gap contact-segment resistance strengthens, motor operation contact-segment temperature raises and makes the corrosion oxidation aggravation, producing vicious circle causes contact-segment to occur smoldering, accident such as burn, have a strong impact on the useful life and the quality of washing machine drainage motor.
Chinese patent literature CN2011136Y provides a kind of " permanent magnetic synchronization motor for water discharge pump ", by adopting plastics or epoxy resin aluminium enamel-covered wire is enclosed in the container, has solved the easily oxidized problem of aluminium enamel-covered wire tie point.But motor in use, and aluminium enamel-covered wire heat and thermal stress of producing in the container of sealing can't discharge, and can cause the swell of being heated of plastic packaging closed container, has a strong impact on plastic packaging quality and outward appearance.In addition, the compression shock in the plastic packaging process can cause aluminium enamel-covered wire and pad to have the risk of damaging, and complex technical process, and cost is higher.
In addition, the aluminium enamel-covered wire in the stator module and hot protection need realize being connected by patching sheet in one, cause cost to rise and the operation increase.
In sum, in order to overcome risk and the cost pressure that drainage pump of washing machine permanent-magnetic synchronous motor stator coil windings aluminium enamel-covered wire plastic packaging brings, develop simple, the lower-cost a kind of drainage pump of washing machine electric machine with aluminium winding of technology.
