How do you determine the three-phase motor U-V-W

Premise is three-phase motor,if there is no any label,see terminal,open connection guide,top left first for U1,followed by V1,W1,and then the remaining 3 size is measured with a multimeter ohms range,in turn,the same for each of the corresponding winding tail.1 the three-phase asynchronous motor U,V,W between conduction? I use a multimeter test of three-phase asynchronous motor,U,V,W three terminal,why it is connected between the two? That is between each two phase is conduction,is this normal? Whether internal short circuit? Tong is certain,regardless of the delta connection or y connection,between them are interlinked,this is normal.Delta connection of resistor is equal to two coil series again and after wholesalemotor.blogspot.com the third parallel resistor,y connection is equal to the resistance after two coils in series.2 motor three-phase winding is same or U V to W almost no resistance,but after the power supply can operate properly,what reason is this? 

Electrical single phase asynchronous motor wiring has been disconnected.You can measure the dc resistance,generally winding dc resistance is small.In ac motor winding inductance coil,then it has impedance,so when it is bubbled into alternating current will not burn.3,a motor,in the case of no electricity,U,V two phase winding resistance value is 5.4 euro,W phase for the more than 100 thousand,this shows that 5kw permanent magnet generator what is the problem? Interturn problems,may be insulation electric motors price damage,check the winding,again,such as resistance balance again electrify,right?4 "2nd level of the motor insulation resistance in general in many megohm range? Cold insulation resistance should be greater than the general motor (1000 + U) / 1000.U for the winding of the rated voltage,resistance to (mge) insulation resistance value is much bigger in practice,it is affected by temperature and humidity of the air,but also the lowest not less than 1 megohm.
