Description

Technical Field

[0001] This utility model relates to the field of shaded-pole motor technology, and in particular to an improved circular two-pole shaded-pole motor. Background Technology

[0002] In the field of motor manufacturing, circular two-pole shaded-pole motors are widely used in devices such as fans and small household appliances due to their simple structure and low cost. However, traditional circular two-pole shaded-pole motors have many shortcomings in practical use and are difficult to meet the ever-increasing performance requirements of modern industry and life.

[0003] On the one hand, the existing protective structure design of shaded-pole motors is not perfect. The rotor and stator windings inside lack effective sealing protection, and external impurities such as dust and moisture can easily penetrate into the motor, accelerating winding aging and corrosion, leading to frequent motor failures and shortening service life. At the same time, the connection structure between the motor housing and various components is not stable enough. During long-term operation, affected by factors such as vibration and external impact, components are prone to loosening and falling off, further reducing the durability and reliability of the motor.

[0004] On the other hand, installation size is a major drawback of traditional shaded-pole motors. The excessively large structural dimensions, such as rotor height and stator winding height, restrict the product's range of applications and types, preventing the use of some electrical appliances in limited installation spaces. This limits the application of traditional shaded-pole motors in household appliances. Operating noise is another major drawback of traditional shaded-pole motors. During operation, the mechanical vibrations and electromagnetic noise generated by rotor rotation and stator winding electromagnetic interactions are significant, affecting not only the user experience but also potentially causing noise pollution to the surrounding environment.
