Embodiment Construction
[0039] Various embodiments of the present invention will be described with reference to the accompanying drawings. In the description and drawings, elements with similar structures or functions will be denoted by the same symbol. It can be understood that the drawings are only used for reference and description, and are not intended to limit the present invention. The dimensions shown in the drawings are only for the convenience of clear description, and do not limit the proportional relationship or give an exhaustive description of the present invention, nor limit the scope of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention.
[0040] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a compone...

The invention relates to a single-phase motor. The single-phase motor comprises a housing, a rotor and a stator; the stator is fixedly installed on the housing; the rotor comprises a rotation shaft and a rotor main body sleeving the rotation shaft; the rotation shaft can be rotatably installed on the housing; the rotor main body can rotate under an electromagnetic force of the stator; the rotor main body is in loose fitting with the rotation shaft in order to make the main body of the rotor to slip relative to the rotation shaft when a motor is started; the single-phase motor also comprises an elastic member; one end of the elastic member is directly or indirectly connected to the rotor main body and the other end of the elastic member is directly or indirectly connected to the rotation shaft for making the main body of the rotor synchronically rotate with the rotation shaft in a delay manner. The motor of invention can arrange the elastic member inside an end cover of the motor, which makes the structure of the motor more compact, and a load impeller is directly connected to one end of the rotation shaft which projects out of the end cover. The single-phase motor and fan using the same is easy to maintain and replace.
Description
technical field [0001] The invention relates to the field of motors, in particular to a single-phase motor and a fan using the motor. Background technique [0002] Driven by a motor to rotate the impeller, it is widely used in fans, dishwashers and other fields. At present, the commonly used motor drives the rotation of the impeller. The impeller is usually installed on the rotating shaft of the motor, and the rotation of the impeller is driven by the motor. When the moment of inertia of the load is too large, the motor may fail to start because it cannot provide enough rotational torque at the moment of starting, and may damage the motor. [0003] If the motor is a synchronous motor or other motors with small output torque, it is more likely to suffer from the above problems. In order to solve the above start-up problem, our company previously designed to install a buffer device between the shaft and the impeller. However, installing the buffer device outside the motor m...
