FIELD: electric engineering, in particular, electric motors with constant magnets.
SUBSTANCE: electric motor with constant magnets includes stator with a winding wound on it and a rotor with magnets. Magnets of the rotor are made of different materials which have different energy values. Thickness of a strong magnet is less than thickness of weak magnets.
EFFECT: reduced growth of material costs of manufacture of magnets, improved torque and increased power of electric motor.
