PROBLEM TO BE SOLVED: To provide a motor producing high torque by reducing cogging. SOLUTION: A motor 10 is constituted of a shaft 11, a stator 30 fixed to the shaft 11, and a rotor 20 disposed so as to rotate around the shaft 11 against the stator 30. The rotor 20 has a magnet 23 so formed as to have 10×(n) magnetic poles ((n) is a natural number). The stator 30 holds a ring 33 fixed to a stator housing 31 and an insulator 35 wound with a coil 36, with its one end fixed to the ring 33 and the other end formed with a salient pole section 34b. The salient pole section 34b has an iron core 34 which constitutes a magnetic circuit together with the magnet 23 of the rotor 20. The magnetic core 34 is so disposed as to have 12×(n) magnetic poles ((n) is a natural number).
