具体实施方式 Detailed ways

本实用新型的马达铁心结构,如图2所示,该铁心主要由一概呈环状的轭部10、多数个概呈T状的齿部20所构成,其中:该轭部10为一体成型,其内环处的壁面设置有与齿部20数量相对的嵌合槽11,本实用新型中以鸠尾槽为其实施例。 The present invention is a motor core structure, shown in Figure 2, the primary core 10, takes the form of a plurality of T-shaped tooth portion 20 is constituted by an annular yoke portion not and will form, wherein: the yoke portion 10 are integrally formed, the inner wall surface thereof at the number of teeth 20 is provided with opposing fitting groove portions 11, the present invention is to dovetail its embodiment.

各齿部20为一体成型,且齿部20尾端设置有与嵌合槽11对应的嵌合部21,本实施例中为鸠尾导轨。 Each tooth portion 20 is integrally formed, the tooth and the trailing end portion 20 is provided with a fitting portion 11 corresponding to the fitting groove 21, dovetail guides for the present embodiment.

如图3所示,组设时,主要通过一治具,将各齿部20后方的嵌合部21与轭部10上的嵌合槽11相对应后,一同将各齿部20嵌设于轭部10的内环中,进而构成一铁心。 3, when the group is provided primarily by a jig, after 11 corresponding to the fitting groove 20 on the rear side 10 of each tooth fitting portion 21 and the yoke, with the teeth portions 20 embedded in the the inner yoke 10, thus to constitute a core.

如图2及图3所示,整体铁心于绕线动作时,可预先于各齿部20直接进行绕线的动作,或是进一步于一绝缘线架30上预先进行绕线,再将绕线完成的绝缘线架30套设于齿部20外侧,而利用治具将齿部20与绝缘线架30一同压入轭部10中,同时通过嵌合部21与嵌合槽11的对应,使齿部20不易脱离轭部10,即可构成一完整铁心结构。 2 and 3, when the entire core in a winding operation, the operation may advance directly to the winding 20 of the teeth, or on a further insulating the winding bobbin 30, and then winding advance accomplished simultaneously by fitting the fitting portion 21 corresponding to the groove 11 of the insulating bobbin 30 is sleeved on the outer teeth portion 20, and the tooth portion by using the jig 20 and the insulating bobbin 30 with pressed into the yoke 10, the tooth portion 20 easily from the yoke portion 10, to form a complete core structure.

值得一提的是,本实用新型中的使齿部20与轭部10各自进行冲片制造,因此当齿部20在绕线的过程中,不会受到空间的限制,甚至可于齿部20外直接套设一已预先进行绕线的绝缘线架30,再将齿部20嵌设于轭部10中,如此不但能大大改善传统铁心加工性差的问题,也可增加铁心制造上的产能。 It is worth mentioning that, in the present invention, the teeth portion 20 of the yoke 10 for punching each sheet manufacturing, so that when the tooth portion 20 during the winding, the space is not restricted, even in the tooth portion 20 an outer sleeve disposed directly for a pre-insulated winding bobbin 30, and then the teeth part 20 is embedded in the yoke 10, so not only can greatly improve the problem of poor workability conventional core, also increase the manufacturing capacity of the core.
