A permanent magnet motor includes a stator core including a core portion and chip portions each formed of dust core, a stator having a coil wound on the stator core and a rotor. The core portion includes steel plates stacked and secured to one another and an annular path portion and salient pole portions. The chip portions are attached to distal ends of the salient pole portions respectively, each chip portion having at least one axial end axially protruding from an axial end of each salient pole portion and one or more radially extending protrusions. The salient pole portions are magnetically routed by the path portion. The salient pole portions have distal end sides formed with recesses capable of accommodating the protrusions, respectively. The protrusions are accommodated in the respective recesses so that the chip portions are attached to the core portion. |
