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!

Pitch是节距的意思. short-pictch 也译作短接
三相绕组的相带(说明)
在下面的图9里展示了一个简单的方法: 怎样用不同的方法完成三相绕组的节距/搭起(或连接).
a)阶梯线圈绕组的短节距/短接.
b)用不同的相带和没有短节距/短接的阶梯线圈(绕组)
c)通过两者的结合（这里没有显示,但基本上可行的）此外,它表明,a和b的电是完全等效.作为一个标准的短接率它等于带传播率,两个绕组的绕组系数必须相等!正常情况下,迭绕组在a)的情况下是首选的,特殊情况下,圈式绕组及波绕组在b)的情况下首选的, 因为正常所用的钢筋连接器的数量会比在a)情况下用的少, 尤其是如果使用了分数波绕组
