Answer Posted / sasi karthick a
it is standard 6 terminal with 3Starting and 3ending points
of windings. Plz refer the below link for connection
diagram.
for low voltage motors,
Upto 2HP/1.5kW - star
above 2HP/1.5kW - Delta
With the same winding, power of the motor varies 3:1 ratio
in Delta to star.
