Electric motor - Electric motor - Permanent-magnet motors: The magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor. In some motors, these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap Permanent magnet (PM) motors are used in many high-end applications, such as in electric and hybrid vehicles. An important design limitation is that the magnets are sensitive to high temperatures, which can occur through heat losses caused by currents, particularly eddy currents Because you always have a rotor magnet, you always have a drag on the rotor wither it is energized or not. An induction motor looses drag because shutting down the Stator field eliminates the Rotor magnetic field.
