PROBLEM TO BE SOLVED: To provide a motor that is easy to change the number of poles and is able to obtain high quality output.SOLUTION: In a brushless motor, single motors Ma of the same configuration are axially arranged in three layers in the following order: a U-phase motor part Mu, a V-phase motor part Mv, and a W-phase motor part Mw. A rotor for each single motor Ma has a Lundell type structure, and is formed from an annular magnet 83 and first and second rotor cores 81, 82 having first and second rotor-side pawl-like magnetic poles 85 and 87. Additionally, a stator for each single motor Ma has a Lundell type structure, and is formed from a coil part 93 and first and second stator cores 91 and 92 having first and second stator-side pawl-like magnetic poles 95 and 97. |
