Winding Connection

 

 

1. Common winding connection are △ and Star (Y).

 

                                          △                                                                                                                                                                                                                                                           Star (Y)

 

 

 

2. The winding commection of three phase double voltage single speed motor: 2△/△ and 2Y/Y

 

 

 

 Outgoing terminal mark
