I've made lots of machines with old 1/4 or 1/3 horse motors out of appliances and never had to start one by hand or had one burn out.
G’day; Could it be that the motor which had to be hand started
had a) a faulty/dirty starter switch incorporated or lacked the
essential capacitor? Most AC motors of 1/4 hp and above have an
internal switch and a capacitor. They are called ‘squirrel-cage’
induction motors and don’t have brushes. Or b) the motor in
question was a 3 phase motor? If you try to operate those on a
two phase system they won’t turn. By the way; when a motor
‘burns out’ it means that someone has given it far too much work
to do - they have overloaded the poor thing. And if we are
heavily overloaded we blow a wire and soon burn out too. Don’t
we? Cheers.
