Abstract

PURPOSE:To reduce the fluctuation of a rotary speed by providing a plurality of permanent magnets to be arranged in a casing of a rotor while composing these permanent magnets of magnet material of small specific gravity. CONSTITUTION:A fan driving electric motor has a rotor 4 and a stator 5 formed by providing a coil 40 for generating a rotating magnetic field. A plurality of permanent magnets 20 are arranged in a casing 15 of the rotor 4. These permanent magnets 20 are formed of a magnet material of ferrite or the like with small specific gravity, being magnetized in the radial direction further in a manner wherein surfaces next to each other are mutually different in the internal peripheral surface making the magnet face to the stator 5.
