<P>PROBLEM TO BE SOLVED: To provide a motor capable of attaining miniaturization, improvement in efficiency, cost reduction and enhancement in quality by the motor that does not use permanent magnets or does not use fewer permanent magnets. <P>SOLUTION: In the motor, teeth for salient poles and a rotor including the salient poles consisting of a soft magnetic material are configured by three phases, full-pitch winding and concentrated winding so that each tooth 117, 118 and 119 for a stator 110 and the salient poles 161 and 162 constituted of the soft magnetic material of the rotor can generate an attraction force discretely in a high flux density. In addition, windings 111 to 116 are formed in a motor configuration, capable of being driven by a one-way current, and the motor can be driven at a low cost with high efficiency; and further, a magnetic saturation reducing measure that applies bias flux and approximately doubling the flux fluctuation range of the soft magnetic material is carried out, and a maximum torque can be increased. <P>COPYRIGHT: (C)2010,JPO&INPIT |
