what is the differences between single phase ind. motor and three phase ind.motor?..

Answer / manish gupta

there is much difference in single phase induction motor and three phase induction motor. First,single phase induction motor is not self starting it requires some capacitor to create voltage difference to start.While three phase induction motor is self starting it do not require capacitor to start.
second single phase induction motor is used for small load eg. fan etc. while three phase induction motor for large load eg. lift,elevator etc.
third single phase induction motor uses less power while 3-phase induction motor uses much power.1-phase are smaller in size while 3-phase induction motor are bigger in size
