PURPOSE:To obtain a low-cost motor having excellent magnetic efficiency by inserting a coil into an approximately U-shaped portion which is made of a round bar comprising high-permiability material, thereafter forming magnetic poles by bending the both ends of the far into a specified shape. CONSTITUTION:A stator core 1 comprising a high-permiability round-bar material such as Permalloy and the like is formed in an approximately U-shape so that the distance C between opposing-end portions 2 and 3 becomes a specified distance. An exciting coil 4 having a coil frame 5 around which copper wire and the like are wound is installed in one portion of the stator core 1, e.g., the portion 2. Both ends of the opposing portions 2 and 3 of the stator core 1 are bent in a specified shape to form magnetic poles, with a specified space being provided from a rotor 6. |
