PROBLEM TO BE SOLVED: To provide a motor capable of improving balance of induced voltages generated in single motor units of respective phases.SOLUTION: Each of single motor units constituting a brushless motor 10 includes: a rotor part configured by arranging a field magnet 23 between first and second rotor cores 21, 22 and allowing first and second rotor side pawl-like magnetic poles 25, 27 to function to alternately different magnetic poles; and a stator part configured by arranging a coil part 33 between first and second stator cores 31, 32 and capable of switching polarity of the first and second stator side pawl-like magnetic poles 35, 37 on the basis of energization to the coil part 33. The single motor units arrayed in a plurality of stages are comprised of two U-phase motor units Mu1, Mu2, one V-phase motor unit Mv and one W-phase motor unit Mw, and the U-phase motor units Mu1, Mu2 are arranged on both end stages in an axial direction. |
