The motor of by only two triangular method

Motor delta connection reward points:5 - time of settlement:the 2010-6-12 six 09:31 motor terminal:U1,W1,U2,V1,V2,electric motor cooling fan W2.Now getting into a triangle,it should be end to end,namely W2 U1,U2 V1,W1 meet V2.But if I pick up my V2 U1,U2 V1,W1 meet W2.So what could be happening? Motor start electric motor cooling fan up? Electricity chance to burn? Question ID:52153 questioner:empty sky - senior level 2 best answer motor connect triangle only two configurations:positive sequence and negative sequence.Positive sequence U1V2 V1W2 W1U2 connect together,negative sequence U1W2 V1U2 W1V2 connect together.Remove the two connection and other connection is wrong.W1 W2,W phase winding by without current.Motor access only U V two phase winding,motor stator winding can only form a pulsating magnetic field,motor open www.dongfeng-motor.com phase starts,burning motor.
