Electric Motors

  • An electric motor is an electrical machine that converts electrical energy into mechanical energy.
  • Every electric motor is caused to turn by the interaction of two magnetic fields, one on the rotor and one on the stator, influencing each other. Different motor types create and control these fields differently.
