introduction：（1）Motor triangle connection because there is no neutral point，The specific method is the motorThe head and tail of the three-phase winding are separately connected，There is only one voltage level，Line voltage equals phase voltage，The line current is equal to the phase current1，73times。 （2）Motor star connection because of the neutral point（The motor is generally three-phase symmetrical load, so it generally does not lead to a neutral line），The specific method is that the three tails of the three-phase winding of the motor are connected together，Three heads are connected to the power supply，There are two voltage levels，Namely line voltage and phase voltage，And the line voltage is equal to the approximate phase voltage1.73times，Line current equals phase current。 （3）It should be noted that the motor with the original star connection cannot be connected into a triangle，（If you make a triangle，Then the phase voltage rises to about1.73times，Long running will burn the motor）。
