<p>Disclosed is a rotator core having an improved quality and an improved reliability thanks to prevention of core crack of the rotator core. The rotator core (10, 25) provided with a laminate of substantially cylindrical core blocks (12, 13, 26, 27, 28) and magnets (20) is characterized in that the core blocks (12, 13, 26, 27, 28) have magnet-accommodating holes (16, 17) extending in the axial direction to the core blocks (12, 13, 26, 27, 28), the magnets (20) are accommodated in the magnet-accommodating holes (16, 17) and secured with resin and that the axial position(s) of the core block boundary surface(s) (23, 30, 30a) along which the core blocks (12, 13, 26, 27, 28) are in contact with each other (one another) and the axial position(s) of the magnet boundary surface(s) (22, 31) along which the magnets (20) are in contact with each other (one another) are different.</p> |
