PROBLEM TO BE SOLVED: To provide an electric motor capable of preventing deterioration of insulation resistance.SOLUTION: An electric motor includes: a yoke (10); a permanent magnet (11) fixed to inside the yoke; a rotor (20) having a commutator (22) and supported rotatably in the yoke; and a brush (15) for supplying current to the commutator (22). A coat (110a) having electrical insulation properties and a coat (110b) having low friction resistance are stackedly formed in order from the permanent magnet side on the surface of the permanent magnet (11). |
