　双速电机的6根线接法一般分为两组：高速线和低速线，每组各三根线。接控制器时需要根据具体的控制器类型和连接方式进行接线。以下是一种可能的接线方法：

　　先确定高速线和低速线。高速线通常标有H、HS、H1等标志，低速线通常标有L、LS、L1等标志。如果没有标志，可以通过测量线圈阻值或者直接试错来确定。

　　将高速线和低速线各自连接到控制器的高速输出和低速输出。具体的接线方式要根据控制器的输出类型来确定，常见的有继电器输出、晶体管输出、脉冲输出等。

　　将电机的公共端（COM）接地，即连接到控制器的GND端。

　　如果需要反转电机方向，可以通过交换高速线和低速线中的任意两根来实现。

　　需要注意的是，接线时要保证电源和控制器的额定电压和电机的额定电压相同，否则会影响电机的性能和寿命。此外，接线时还要注意电机的额定电流和控制器的输出电流是否匹配，以避免电机过载损坏控制器。
