A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
AC motors convert electrical energy into that of mechanical. ... Most AC motors produce the current by using induction. An electromagnet causes the magnetic field and uses the same voltage as the coils do.
