Technical field
The present invention relates to washing machine technology field, particularly washing machine directly drives induction machine.
Background technology
Current washing machine industry direct driving motor used is brshless DC motor, and non-direct drive motor used is induction machine.
When brshless DC motor runs, need supporting special drive plate, overall cost is relatively high, and electronic component required for drive plate is more, and rate of breakdown is also relatively high, and product reliability is relatively low; Equipment required for brshless DC motor manufactures is more, and required precision is higher, and manufacture difficulty is comparatively large, and manufacturing cost is higher, so use the washing machine cost of brshless DC motor higher, popularity rate is lower.
Non-direct drive motor is induction machine, needs belt to be connected with decelerating clutch of washing machine and drives, and for internal rotor drives, axial dimension is comparatively large, and moment of torsion is relatively little.
Summary of the invention
The object of the invention is: provide a kind of washing machine directly to drive induction machine, to reduce washing machine direct driving motor cost, also reduce failure rate simultaneously.
According to above-mentioned purpose, basic technical scheme of the present invention is: a kind of washing machine directly drives induction machine, comprises stator and cage rotor, and stator and cage rotor are arranged with one heart, it is characterized in that: described cage rotor is positioned at the outside of stator.
Described cage rotor comprises inner electrical steel strip and the aluminium ring of outside, is connected outside described cage rotor with rotor case.
Described stator comprises inner electrical steel strip and the electromagnetic wire of outside, is connected in described stator with stator set casing.
Described rotor case is installed with cage rotor is concentric, and the center of described rotor case is provided with the connecting hole concentric with cage rotor.
Together with described electrical steel strip and aluminium ring are connected by the form of aluminium die casting.
Described stator set casing is installed with described stator is concentric, and described stator set casing is provided with dowel pins pump ring and stator installing hole.
Together with described electromagnetic wire and electrical steel strip are connected by the mode of rule.
Compared with prior art, advantage of the present invention and beneficial effect:
1, the present invention directly drives when induction machine runs and does not need supporting special drive plate, and reliability is relatively high, and its manufacturing process relative maturity, equipment needed thereby is less, and manufacture difficulty is relatively low, and cost is lower, easily popularizes.
2, the present invention directly drives induction machine and uses external rotor electric machine, moment is relatively large, is also convenient to be directly installed on clutch coupling of washing machine, saves axial installation dimension, the overall volume of washing machine can be done relatively less, and the entirety reducing washing machine takes up room.
