Winding Connection

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

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

Outgoing terminal mark 

Voltage	Connection	L1	L2	L3	Connected
230V	2Y	T1,T7	T2,T8	T3,T9	(T4,T5,T6)
460V	Y	T1	T2	T3	(T4,T7) (T5,T8) (T6,T9)
230V	2△	T1,T6,T7,(T12)	T2,T4,T8,(T10)	T3,T5,T9,(T11)	--
460V	△	T1	T2	T3	(T4,T7) (T5,T8) (T6,T9)
