定子和旋转变压器
摘要：
定子（10）具有定子铁芯（12）和多个线圈，所述定子铁芯（12）具有多个环形地设置的磁极齿，所述多个线圈分别由电线缠绕在多个磁极齿上而形成，其中：用于单个相位的线圈组由多个线圈串联而成，从而使得磁通量分布为正弦波分布；所述用于单个相位的线圈组由多个线圈匝构成，所述线圈匝由缠绕在两个相邻磁极齿上的两个线圈串联而成；从定子的内部看，缠绕在两个磁极齿上的、组成每个线圈匝的两个线圈彼此按相反方向缠绕；从每个线圈的末端绕组伸出的电线连接至与该线圈的起动绕组相连的电线，再连接至沿相反方向缠绕的下一线圈的起动绕组，然后连接至接线端子。
摘要（英）：

A stator (10) has a stator core (12) with a plurality of magnetic pole teeth arranged annularly, and a plurality of coils formed by respectively winding electrical wires around the plurality of magnetic pole teeth, wherein a coil group for a single phase is formed by serially connecting a plurality of coils so that resulting magnetic flux distribution is a sine wave distribution, the coil group for a single phase is constituted by a plurality of coil sets, formed from two coils that are wound around two adjacent magnetic pole teeth, connected in series, two coils that are wounded on the two magnetic pole teeth and constitute each coil set are wound in opposite directions to each other looking from the inside of the stator ,and an electrical wire extending from an end winding of each coil is connected to an electric wire connected with a start winding of the coil, then is connected to a start winding of the next coil wound in the opposite direction, and then is connected to a connection terminal.
