1. a motor (10,40,50,60), it possesses:

  • the first motor key element (12,64) with iron core (16,66) and a plurality of coil (18,68);

    And have a plurality of permanent magnets (20,70) that form a plurality of magnetic poles and second a motor key element (14,62) that relatively disposes with the above-mentioned first motor key element (12,64), this motor (10,40,50,60) is characterised in that,Above-mentioned a plurality of coils (18,68) of the above-mentioned first motor key element (12,64) are by supplying with the electric current of three-phase alternating current, thereby interact with above-mentioned a plurality of permanent magnets (20,70) of the above-mentioned second motor key element (14,62) and produce the thrust of this motor (10,40,50,60)Be formed with towards the outstanding a plurality of teeth of the above-mentioned second motor key element (14,62) at above-mentioned iron core (16,66), these a plurality of teeth comprise the main tooth (24,76) that is wound with above-mentioned coil (18,68) and the secondary tooth (26,78) that is not wound with above-mentioned coil (18,68), these main teeth (24,76) and secondary tooth (26,78) alternately disposeThe number of poles that is formed by above-mentioned a plurality of permanent magnets (20,70) of the above-mentioned second motor key element (14,62) is that 4m compares 3n with the ratio of the number of phases that the above-mentioned a plurality of coils (18,68) by the above-mentioned first motor key element (12,64) form, wherein, m and n are natural numbers arbitrarily, the situation except 2 to 3.
