<P>PROBLEM TO BE SOLVED: To provide a rotor capable of generating a magnetic field necessary for a claw-shaped magnetic pole of each rotator with a small number of components, and a motor. <P>SOLUTION: A rotor 3 of a motor includes a first rotator 4 having a plurality of claw-shaped magnetic poles 8 arranged at equal interval in a peripheral direction of the rotor, and a second rotator 5 which has a plurality of claw-shaped magnetic poles 11 arranged at equal intervals in the rotor peripheral direction as well and protruding to the opposite side from the claw-shaped magnetic poles 8, the rotators 4, 5 being incorporated such that the claw-shaped electrodes 8, 11 thereof are arranged alternately in the rotor peripheral direction. The first rotator 4 is formed of a soft magnetic material such as iron, the second rotator 5 is formed of a magnet, and magnetic moment is generated in the first rotator 4 with magnetic force of the second rotator 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
