Hey can any one please help me here,
smaller motors can either be connected in star or delta right, but how do you decide? I was taught that it depends on what it would be used for. Like star will give 220 across the windings and have less torque, Delta will have 380 across windings and give more torque. So delta if motor is going to work hard and star otherwise???? Is this way of thinking correct?
Other side is that it depends on the supply voltage.
3phase 220v or 3phase 380v, dictates the connection.
So please can any one clear this up for me.
O and if i have a drive that is supplied by 220 and in turn supplies a 3phase motor how should that motor be connected and y??
