PROBLEM TO BE SOLVED: To provide a rotor that can reduce cogging torque.SOLUTION: First and second rotor cores 21 and 22 and third and fourth rotor cores 31 and 32, which are plural pairs of rotor cores, are disposed in such a way that the rotor cores 22 and 31 of the same polarity are disposed adjacent to each other, and are shifted in a circumferential direction between the individual pairs of rotors 21, 22, 31 and 32.SELECTED DRAWING: Figure 2 |
