Below we will use the most conventional three-phase asynchronous motor wiring method to explain to you, a motor wiring method is connected into a star or into a triangle, should be carried out according to the manufacturer's regulations,  It can be viewed from the motor nameplate. The head and end of the three-phase stator winding are set in advance by the manufacturer and must not be reversed arbitrarily.

       Let's look at the wiring diagram first:

       Three-phase asynchronous motorThere are two types of wiring. One is the star connection method, the tail and tail of the three-phase winding are connected together, and the three heads are used as star points; Or the head and the head together, the three ends as stars; therefore6A joint refers to the connection3One can operate the connection mode, called the star connection, also known asYV-connection.

       if-will6The joint is divided into three groups, each group of two heads, in order to connect three contacts, respectively connected to the power supply, is a triangle; willU1W2-W1V2-V1U2The three contacts that come out in turn are respectively connected to the power supply, which is the triangle connection method, also called△Connect.
