The utility model compared with prior art, has following major advantage:
1, when the motor winding to different capabilities and electric pressure detects, can be according to the different choice test voltage grade of the induction reactance of winding, equivalent no-load voltage ratio, sensing range is wider;
2, testing result can embody more intuitively by the mode of bright light, by different colours pilot lamp, increase the reliability of winding polarity testing result, reduce the polarity misjudgment phenomenon that traditional direct current break-make method is caused by human factor when detecting motor winding polarity, reliability is higher;
3, test voltage grade realizes a minute compression functions by divider resistance dividing potential drop and gearshift button, and due to resistance current limliting reason, and it is short to detect conduction time, even the pressure drop of winding self-resistance is very little after a period of time, also can therefore not cause power supply short circuit problem;
4, two covers detect loop only needs people's operation once to test the polarity detection that just can simultaneously complete motor three phase windings, and principle is simple, has improved test efficiency;
5, device is by storage battery power supply, lightweight, is easy to carry.
