Abstract
A brushless motor includes a rotor. The rotor includes a first rotor core, a second rotor core and a field magnet. The first rotor core includes a plurality of first magnetic pole portions arranged in a circumferential direction. The second rotor core includes a plurality of second magnetic pole portions arranged in the circumferential direction. The field magnet is arranged between the first rotor core and the second rotor core in an axial direction. When the field magnet is magnetized in the axial direction, the first magnetic pole portions function as first magnetic poles and the second magnetic pole portions function as second magnetic poles.
