Answer / lokeshraj

The voltage aplied to a moter terminal is the line to line
(LINE VOLTAGE). In star connection the phase voltage is
Vph/root(3) and in case of delta connection in is
Vph=V(line). And the voltage applied to the each winding is
the phase voltage that is greater in case of phase
connection so higher speed.

Answer / a.k.rai

Motor speed is same in both delta as well as star connection.
What varies is the shaft power developed by motor.
