Non-direct drive motor is induction machine, needs belt to be connected and to drive with decelerating clutch of washing machine, and for internal rotor drives, axial dimension is larger, and moment of torsion is relatively little.
Summary of the invention
The purpose of this utility model 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 utility model is: a kind of washing machine directly drives induction machine, comprises stator and cage rotor, and stator and cage rotor arrange with one heart, it is characterized in that: described cage rotor is positioned at the outside of stator.
Described cage rotor comprises the aluminium ring of inner electrical steel strip and outside, and described cage rotor outside is connected with rotor case.
Described stator comprises inner electrical steel strip and the electromagnetic wire of outside, in described stator, is connected 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 the aluminium ring form by aluminium die casting is connected.
Described stator set casing and described concentric installation of stator, described stator set casing is provided with dowel pins pump ring and stator installing hole.
Together with described electromagnetic wire and the electrical steel strip mode by rule is connected.
Compared with prior art, advantage of the present utility model and beneficial effect:
When 1, the utility model directly drives induction machine operation, do not need supporting special-purpose drive plate, reliability is relatively high, and its manufacturing process is relatively ripe, and equipment needed thereby is less, and manufacture difficulty is relatively low, and cost is lower, easily universal.
2, the utility model 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, has saved axial installation dimension, the overall volume of washing machine can be done relatively littlely, and the integral body that has reduced washing machine takes up room.
