Abstract
The utility model discloses an external rotor-type AC electromotor, which comprises a rotor (1) and a stator (2), wherein, the stator (2) is arranged inside the rotor (1), an insulated framework (3) insulating with a fixing installation part of the stator is arranged on a lateral side of a loop of the stator (2), the insulated framework (3) is fixed on an iron core of the stator, and the loop of the stator (2) is fixed on the insulated framework (3). The insulated framework (3) is provided with a plurality of through holes (31) used for both ventilation and radiation, and connection, and the stator (2) is bounded on the insulated framework (3) through a threading and a plurality of through holes (31) on the insulated framework (3). Due to adoption of the insulated framework structure which is insulating with the fixing installation part of the stator arranged on the lateral side of the loop of the stator, causing the loop of the stator to be fixed on the insulated framework, the utility model can effectively prevent the loop of the stator from descending along the axial direction, resulting in safe application of the electromotor. The utility model is a new external rotor-type AC electromotor with the advantages of smart design and safe and reliable application.
Description
1, technical field:
The utility model is a kind of external-rotor-type alternating current motor, particularly a kind of external-rotor-type alternating current motor that is used for washing machine.
2, background technology:
The used external-rotor-type alternating current motor of existing washing machine is installed in rotor outlet structure in the rotor for adopting with stator, the shortcoming of its existence be motor in the course of the work, because vibration is bigger, its stator coil tends to the phenomenon that occurs in axial direction sinking, cause producing between rotor rotated and the stator coil friction, can cause stator coil short circuit or motor rotor to be stuck when serious, thereby make burn-down of electric motor.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of novel external-rotor-type alternating current motor that can prevent effectively that stator coil from axial direction sinking is provided.The utility model design is ingenious, safe and reliable.
Structural representation of the present utility model as shown in drawings, include rotor (1), stator (2), stator (2) is installed in the rotor (1), wherein the coil of stator (2) outside is provided with the Insulating frame (3) that can insulate with the fixed installation part of stator, Insulating frame (3) is fixed on the iron core of stator, and the coil stationary of stator (2) is on Insulating frame (3).
Have several both to can be used for ventilation and heat on the above-mentioned Insulating frame (3), can be used for the through hole (31) that connects again, the coil of stator (2) by several through holes (31) colligation of making on threading and the Insulating frame (3) on Insulating frame (3).
Above-mentioned Insulating frame (3) is arranged on stator coil one side away from Rotor carriage, and Insulating frame (3) is made by insulating material, makes the fixed installation part insulation of coil and stator.
Make several through holes (31) on the above-mentioned Insulating frame (3) and can be arranged on its side, also can be arranged on its end face, maybe can be arranged on its side and end face.
Above-mentioned Insulating frame (3) can also can glued joint by adhesive by being threaded with the iron core of stator, or by riveted and fixed on the iron core of stator.
The utility model is owing to adopt the stator coil outside to be provided with the structure of the Insulating frame that can insulate with the fixed installation part of stator, because of stator coil can be fixed on Insulating frame, therefore, it can prevent effectively that stator coil from axial direction sinking, thereby guarantees the safe handling of motor.The utility model is that a kind of design is ingenious, safe and reliable novel external-rotor-type alternating current motor.
