<p>A DC motor (11) with an armature coil for generating torque capable of increasing motor efficiency and generated torque while reducing a size and a thickness, comprising magnets (23A) to (23D) and armature coils (31A) to (31C) and (32A) to (32C), wherein, for example, a magnet portion is used as a rotor (12). The stator (13) of an armature coil portion comprises an inner coil group formed by arranging, parallel with each other, hollow inner coil bodies (31A) to (31C) on the peripheral side surfaces of a magnet yoke (22) and the magnets (23A) to (23D) as a virtual disk by a specified quantity and an outer coil group formed by arranging, parallel with each other, hollow outer coil bodies (32A) to (32C) by a specified quantity while covering the inner coil group. The peripheral side surface of the inner coil group is made flush externally with the peripheral side surface of the outer coil group.</p> |
