Single phase motors opreates on netural and line and are
not self started as they have pulasting emf. where as the
three phase motors opreates on three phases and are self
started and are used in industrial applications two phase
motors are very reared used

Answer / jain c

for producing rotating magnetic field we need minimum two
phases. In single phase motor, we are calling single phase
motor but we are splitting the single phase into two phases
by capacitor. The phase angle between that two is 90 degree.
In case of three phase motor the R,Y,B phases produces
rotating magnetic field. The angle between three phases is
120 degree.
