Phase bands (Phase belts) for 3-Phase-Windings (Explanation)
In the Fig.9 below it is shown in a simple way,how the pitching of a 3-phase- winding can
be achieved on different ways:
a.) short-pitching of the winding step
b.) by different phase belts and no short pitching of the winding step
c.) by a combination of both (not shown here,but basically feasible)
In addition it is shown that from the electrical point of view a.) and b.) are absolutely equivalent.As the short pitching ratio of the example is equal to the belt spreading ratio ,the winding
factors of both windings must be equal too!
Normally for lap-windings case a.) is preferred,especially for coil-windings.For wave-windings case b.) is preferred because normally the number of bar-connectors is less than for case a.),especially if fractional wave windings are used!

3相线圈之相位带浅析
如下简图9中所示,3相线圈倾斜方式有多种：
a)绕向短倾
b)异种相位带代绕向短倾
c)二合一（此处未示意,但原则可行）
此外从电气角度看a)&b)方案可互换.因短倾率等于带展率,所以缠绕参数亦同.
通常绕式线圈多用a)方案,线绕线圈尤甚.波式线圈多用b)方案,因母线接点比方案a)少,特别是采用摩擦式波式线圈时.
