PROBLEM TO BE SOLVED: To provide a Lundell type rotor and a Lundell type motor that prevent a field magnet from being loaded and is capable of preventing the field magnet from being damaged during an assembly work.SOLUTION: A first and a second rotor cores 20 and 30 have through holes 21a and 31a formed at central parts of their core bases 21 and 31. A rotation shaft is press-fitted into the through holes 21a and 31a thereby the first and the second rotor cores 20 and 30 are fixed to the rotation shaft. A sleeve 41 with a length Dx in the axis direction which is longer than a length Dy in the axis direction of a field magnet is externally inserted to a part between the first and the second rotor cores 20 and 30 of the rotation shaft. The sleeve 41 is inserted in a through hole 40a of the field magnet 40 whose inner diameter Dt is larger than an outer diameter of the sleeve 41. The field magnet 40 is adhered to be fixed onto the sleeve 41 with hardening resin which no magnetic flux penetrates. |
