why single induction motor is not self starter?

Answer Posted / paras315

in single phase induction motor stator has single phase
winding,when we give single phase supply, it creats a
pulsating magnetic flux in the air gap but for rotor
rotation there should be a rotating flux.so it is not self
starting.
for starting either auxiliary winding or any means which
splits the single phase flux in at least 2 phase flux can be
used
