PROBLEM TO BE SOLVED: To provide a flat coreless motor in the casing, of which a wiring groove can be secured on the bottom for housing a flexible wiring sheet, and at the same time, the weight of which can be reduced sharply by reducing its thickness and accordingly, its casing. SOLUTION: A flat coreless motor is constituted by the use of a rotor provided with one or a plurality of armature coils, a shaft 23 positioned to the center of rotation of the rotor, field magnets faced to the rotor, and a casing 20 for housing them. A wiring space is formed on the bottom of the casing 20, and at the same time, projections 29 or projected lines are formed on the bottom of the casing 20 to support the field magnets. |
