Summary:PROBLEM TO BE SOLVED: To provide a brushless motor which can hold stator side magnets in a stable manner.SOLUTION: A brushless motor (vernier motor) set to satisfy a formula: the number of slots on a rotor side=the number of slots on a stator side±the number of pole pairs of a coil, includes a pair of magnet holders 36a and 36b formed of a nonmagnetic material, for sandwiching and supporting stator side magnets 34 from both side in an axial direction. The pair of magnet holders 36a and 36b are positioned by being abutted on a housing 11.
