Three-phase asynchronous motor wiring diagram

Three-phase asynchronous motor wiring diagram:three-phase three-phase motor stator winding of each phase winding has two thread ends.A head is called the head end,on the other side called terminal.Provisions of the first phase winding head end use D in table 1 ,end in 4 D; The second phase winding head end with D2,said end D5 said; The third phase winding end of the first represented respectively with D3 and D6.The electric vehicle motors ix thrum import terminal block wiring Column,the terminal marked accordingly D1~D6 tag,as shown in figure (1).Six of the three-phase stator winding end three-phase stator windings can be a star or triangle,y connection is a three-phase winding End up in parallel,the D4,D5,D6 three terminal with copper link together,and the three-phase winding head end access three-phase ac power supply respectively,the D1,D2 and D3 access A and B,respectively C power supply,as shown in figure (2).And triangle by law is the first end of the first phase winding to the 1 D connected to the end of the third phase winding D6,access to another phase power; The second phase winding head end with D2 At the end of the first phase winding connected D4,access to the second phase power; Head end of the third phase winding D3 connected to the end of the second phase wholesalemotor.blogspot.com winding D5,and access to the third phase power supply.In the wiring board will be answered Line column and D6 D1,D2 and D4,D3,and D5 with copper connected respectively,then access to the three-phase power supply respectively,as shown in figure (3).An electric motive is pick a star or triangular,should regard factory rules For,available from the motor nameplate.Is the first of the three phase stator winding end manufacturers set beforehand,never can be arbitrary,but a first end of the three-phase winding up can be reversed, For example will be the motor fan end of the three-phase winding D4,D5,D6 upside down as the head end,D1,D2 and D3 as an end,but never separate the ends of the head of a phase winding upside down,otherwise will produce wrong wiring. If wrong wiring junction box found raw,or winding end of the first mistake,light can't the normal starting motor,long electricity causes starting current too big,motor heating is serious,affect the life, Or burning motor winding,or cause the power short circuit.
