1. Field of Invention
The invention relates to a stator structure and the magnetically conductive element thereof. In particular, the invention relates to a magnetically conductive element integrally formed as a single unit by using a magnetic powder and the stator structure using the same in a motor.
2. Related Art
The basic structure of a motor includes a stator structure and a rotor structure. With reference to
However, the conventional method of forming the magnetically conductive element of the stator structure is complicated. Therefore, the manufacturing cost is high and the yield and the product quantity are low.
Therefore, it is an important subject of the invention to provide a stator structure and the magnetically conductive element thereof that can reduce the manufacturing cost and enhance the performance of the motor.
In view of the foregoing, the invention is to provide a stator structure and the magnetically conductive element thereof. The magnetically conductive element is integrally formed from at least one magnetic powder. It reduces the manufacturing cost, maintains the characteristics, and enhances the performance of the motor.
To achieve the above, the invention discloses a stator structure including a magnetically conductive element and a winding. The magnetically conductive element is integrally formed as a single unit from at least one magnetic powder. The winding winds around the magnetically conductive element.
To achieve the above, the invention also discloses a magnetically conductive element, which is integrally formed as a single unit from at least one magnetic powder.
As mentioned above, the disclosed stator structure and magnetically conductive element of the invention involving at least one magnetic powder (e.g., Fe—Si material) are formed via a molding process, and under predetermined pressure and temperature conditions. The magnetically conductive element is integrally formed as a single unit (by powder metallurgy, thermal press molding or injection molding) after a thermal process. In comparison with the prior art, the integrally formed magnetically conductive element does not involve complicated manufacturing and assembly processes. Therefore, the invention reduces the manufacturing cost. At the same time, the characteristics (such as the DC resistance and core loss) of the motor can be maintained and the performance of the motor can be enhanced.
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
