按,目前常見之馬達結構,可分為內轉子還是外轉子型態,其結構主要由轉子以及纏繞有電樞線圈之定子所組成;其中,轉子係具有一永久磁石,以內轉子為例,該轉子係相對設置在定子中心軸孔處,當馬達運轉時,係先讓該定子所纏繞之電樞線圈產生磁場,並與轉子之永久磁場交互作用產生電磁力,使轉子被驅動而運轉。According to the current common motor structure, it can be divided into an inner rotor or an outer rotor type, and its structure is mainly composed of a rotor and a stator wound with an armature coil; wherein the rotor has a permanent magnet, taking the inner rotor as an example, The rotor system is oppositely disposed at the central shaft hole of the stator. When the motor is running, the armature coil wound by the stator first generates a magnetic field, and interacts with the permanent magnetic field of the rotor to generate an electromagnetic force, so that the rotor is driven to operate.
至於,一般內轉式定子之結構,主要具有一呈圓環狀的本體10,於本體10周緣設有複數相連的軛部11,於各軛部11中央處設有朝本體10中心延伸的定子齒12,且於各定子齒12尾端形成一相互圍繞呈一軸孔狀的靴部13,再藉助模具及繞線機等裝置,將漆包線通過相鄰定子齒12之兩靴部13間隙14,依預設的繞線方向繞在內轉式定子的線軸上,且堆疊形成具有厚度之線圈組15,於使用時,係透過控制電路的控制,令內轉式定子與轉子形成相互作用電磁場,使馬達得以正常運轉。As for the structure of the inner-rotating stator, there is mainly a body 10 having an annular shape, a plurality of yoke portions 11 are provided on the periphery of the body 10, and a stator extending toward the center of the body 10 is provided at the center of each yoke portion 11. The teeth 12 are formed at a rear end of each of the stator teeth 12 to form a shoe portion 13 which is formed in a shaft hole shape, and the enamel wire is passed through the gaps 14 of the two shoe portions 13 of the adjacent stator teeth 12 by means of a die and a winding machine. Winding on the bobbin of the inner-rotating stator according to a preset winding direction, and stacking the coil group 15 having a thickness, and in use, through the control of the control circuit, the inner-rotating stator forms an interaction electromagnetic field with the rotor.
