PROBLEM TO BE SOLVED: To provide an electric motor capable of suppressing generation of a strange sound.SOLUTION: In an electric motor 14, first and second rotor cores 43 and 45 having a plurality of first and second magnetic pole teeth 42 and 44 juxtaposed in a circumferential direction are combined, and a field coil 46 is arranged between the first and second rotor cores 43 and 45, and a rotor 23 making the first and second magnetic pole teeth 42 and 44 alternately function as a different magnetic pole by energization to the field coil 46 is provided. The second rotor core 45 has: a rotation core 53 in which the respective second magnetic pole teeth 44 are juxtaposed, and which is uniformly and rotatably fixed with the first rotor core 43 and a rotation shaft 41; and a fixing core 54 to which the field coil 46 is fixed. In addition, the fixing core 54 is fixed to a housing 21 so that a gap is formed between the first rotor core 43 and the rotation core 53, and a contact prevention member 61 made of a resin material having a self-lubricating property is provided to this gap. |
