Abstract
Asynchronous motor with external rotor for washing machine of the utility model is provided with a rotor and a stator. A shaft hole utilized to connect a main shaft of the washing machine is arranged on an axial direction of a rotating shaft of the motor, the rotating shaft is sleeved with a bearing, the stator is fastened with a support arranged on outer ring of the bearing, the rotor is fastened with the rotating shaft and coaxially cover an outer circle of the rotor with a clearance. When the motor is mounted, the hollow rotating shaft of the motor is cooperatively connected with the main shaft of the washing machine, and a stator support is fastened with a base of the washing machine. As the main shaft of the washing machine is inserted into a shaft hole of the motor and directly connected with the motor shaft, vibration and noise are reduced, and transmission efficiency is improved. Furthermore, tests advise that application of internal stator and external rotor structured motor by a washing machine and arranging a rotor winding on original rotor yoke of an internal rotor type motor can obviously improve torque and efficiency of the washing machine.
Description
Technical field
The utility model relates to outer rotor motor.
Background technology
Present washing machine is mainly driven by common monopole asynchronous motor, motor mounting is in the inner side of washing machine, difficulty is installed machine shaft with the washing machine main shaft is concentric, normally the motor turning moment is transferred to the washing machine main shaft by belt gear, will make motor for the off-centre of washing machine the vibration that causes is installed is like this amplified greatly, the vibration that also exists belt transmission to have horizontal uneven pulling force to produce simultaneously to the washing machine main shaft, during work, the noise of vibration and reduction gearing is big, and the power transmission loss is big, efficient is low.
Summary of the invention
The purpose of this utility model provides and a kind ofly is easy to guarantee that machine shaft and washing machine main shaft are concentric installs, reduces vibration and noise, improves transmission of torque efficient, the use in washing machine asynchronous motor of outer rotor that reduces cost.
The asynchronous motor of outer rotor that is used for washing machine of the present utility model has rotor, stator, machine shaft axially be useful on the axis hole that is connected with the washing machine main shaft, in rotating shaft, be with bearing, stator is fastening with the support that is fixed on bearing outer ring, rotor and rotating shaft are fixed, cover on the cylindrical of stator coaxially, and gapped with cylindrical.
When motor was installed, the hollow rotating shaft of motor and washing machine main shaft were connected, and stator support and washing machine pedestal are fixed.Because the washing machine main shaft is inserted in motor axis hole, directly links to each other with motor shaft, can not only reduce vibration and noise, can also improve transmission efficiency.In addition, test shows, washing machine adopts internal stator, outer-rotor structure motor, and stator winding is placed the position of the former rotor yoke of inner rotor type motor, can obviously improve the moment and the efficient of washing machine.
Description of drawings
Accompanying drawing is the asynchronous motor of outer rotor structural representation that the utility model is used for washing machine.
Embodiment
With reference to accompanying drawing, the asynchronous motor of outer rotor that is used for washing machine has rotor 1, stator 2, and the rotating shaft 3 of motor has axis hole 8, is hollow rotating shaft, be used for linking to each other with the washing machine main shaft, usually, can in axis hole 8, establish keyway or teeth or make the cross section of axis hole be polygon-shaped, in rotating shaft 3, be with bearing 4, stator 2 is fastening with the support 7 that is fixed on bearing 4 outer rings, rotor 1 is fixing with rotating shaft 3, and covers on the cylindrical of stator coaxially, and gapped between cylindrical.In order to limit the rotor axial play, can in the rotating shaft that is positioned at bearing 4 two ends, install spring flange 6 and wavy spring 5 respectively.
