将定子一种极数的磁场感应于转子绕组中的电流，通过集电环和电刷，但由另一种极数的磁场感应的电流，却自动流经另一闭合回路，而不通过集电环和电刷：于是，如果后一种极数是电动机的工作基波磁场，而把前一种极数作为用以起动的谐波磁场，则可以把起动电阻直接焊接在转子绕组上，而把集电环和电刷取消，从而出现了转子电路上无集电环、无电刷、无触点的谐波起动绕线型感应电动机。

When it was dark I set by my camp fire smoking, and feeling pretty well satisfied; but by and by it got sort of lonesome, and so I went and set on the bank and listened to the current swashing along, and counted the stars and drift logs and rafts that come down, and then went to bed; there ain't no better way to put in time when you are lonesome; you can't stay so, you soon get over it.

天黑了，我在营帐边上抽着烟，心里觉得挺满意的。慢慢地又感到有点儿寂寞。我便在河岸上坐下，倾听着流水冲刷河岸声，数数天上的星星，数数从上游漂下来的木头和木筏子，然后去睡觉。在寂寞的时候，这是消磨时间最好的办法了。你不会老是这样的，你很快就会习惯的。
