The invention discloses a double-stator magnetic field modulation permanent magnet motor comprising an inner stator, an outer stator, and a rotor. Air gaps are formed between the rotor and the inner and outer stators. The rotor is formed by magnetic conductors and non-magnetic conductors which are arranged alternately. The outer stator is formed by outer stator teeth, radial magnetizing permanent magnets, and an armature winding. The radial magnetizing permanent magnets adhere to the inner surfaces of the outer stator teeth. Adjacent permanent magnets on the same outer stator tooth have opposite magnetizing directions. The inner stator is just formed by inner stator teeth equipped with grooves along the circumferential direction and an armature winding in the grooves while not being provided with any permanent magnet. According to the double-stator magnetic field modulation permanent magnet motor, the two armature windings are used while the amount of the permanent magnets is not increased. Thus, an armature magnetic field is fully utilized and a power factor and the power density are increased. Compared with a product in the prior art, the double-stator magnetic field modulation permanent magnet motor is not provided with a rotor magnetic conductive yoke portion, decreased in rotor size and iron loss, and increased in the power density and efficiency, and can be used in power systems such as electric automobile, wind power generation or the like.
