一、怎样检查绕组接线接反 电动机绕组接线接反有二种:一种是绕组的个别极相组或个别线圈嵌反;另一种为引出线首末端接反。 1.个别极相组或个别线圈嵌反的检查可用指南针判别法。取出电动机转子,将某相绕组两端接于3～6伏的低压直流电源上(如蓄电池)。用指南针沿定子内圆四周移动(必须逐槽进行),如果线圈未嵌反或接线正确,指南针经过每一个极相将会交替变化一次方向。如指南针经过相邻不同极相组时指针不变,则说明该极相接线有错;如指南针经过同一极相组不同位置时指针变化方向,则说明该极相组有线圈嵌反。
First, how to check the winding connection Reversing the motor winding connection There are two kinds of reverse: one is the winding of the individual pole phase group or individual coil embedded anti; the other is the first end of the lead wire termination. 1. Individual pole phase or individual coil embedded anti-compass can be used to check the law. Remove the motor rotor, the two ends of a phase winding connected to 3 ~ 6 volts low-voltage DC power supply (such as battery). With the compass along the inner circumference of the stator around the movement (must be slot-by-slot), if the coil is not embedded anti-reverse or wiring is correct, the compass through each phase will alternate direction once. If the compass through the adjacent polar phase group pointer unchanged, then the pole phase wiring error; such as the compass through the same pole phase group when the different direction of the needle change direction, then the phase group with embedded anti-coil.
