To provide a synchronous drive motor that satisfies a high torque, a high output, and downsizing at a higher level. A synchronous drive motor includes: a stator including a stator core and windings, the stator core including a plurality of teeth that are spaced from each other by a slot formed therebetween with respect to a circumferential direction, the winding extending through the slot, each of the plurality of teeth including a portion wound with the winding; and a rotor including a permanent magnet part that forms a plurality of magnetic pole faces, the plurality of magnetic pole faces being provided on a surface of the rotor opposed to the stator. Each of the plurality of teeth includes a distal end portion that is opposed to the magnetic pole face. The distal end portion has a smaller circumferential width than a circumferential width of the magnetic pole face, the number of the magnetic pole faces being more than the number of the teeth. |
