PROBLEM TO BE SOLVED: To improve vibration detection precision when used in a washing machine, by eliminating deviation when a magnet is fixed to a yoke for improved fixing-position precision, related to a brushless DC motor which comprises a surface magnet rotor and is driven by an inverter. SOLUTION: A plurality of magnets 9 facing the stator 1 are fixed to a yoke 11 by molding with a resin 10, constituting a rotor 12. Related to the rotor 12, a recessed part 13 is formed on the outer peripheral surface near the proximity part of the adjoining magnets 9. |
