Claims20
A fan system having a three-phase claw-pole motor comprising a stator and a rotor, wherein the three-phase claw-pole motor provides with stator coils for three phases which are arranged on one plane.
An electric motor comprising a rotor, stator and a rotor shaft for supporting the rotor, wherein a portion of the rotor in contact with the rotor shaft is constructed with a non-conductor.
A three-phase claw-pole motor comprising a stator, a rotor and a rotor shaft for supporting the rotor, wherein the three-phase claw-pole motor provides with stator coils for three phases which are arranged on one plane, the rotor provides with a two-color molded magnet integrally molded of a permanent magnet and a dust core yoke, and the rotor provides with a permanent magnet which is spaced with a gap from the magnetic poles of the stator, and the permanent magnet being so shaped as to alter the gap circumferentially.
