PURPOSE:To efficiently absorb the heat generated at an air cvore coil and to diffuse the heat in a rotor for a flat motor by molding a fibrous nonmagnetic metallic piece pressed in a flat shape with resin together with the air core coil, thereby forming the rotor. CONSTITUTION:An air core coil 12 is engaged with the slot of a pressed material 11 formed by pressing a fibrous nonmagnetic metallic piece in a flat shape, and is integrated with resin 14 from the upper and the lower surfaces, thereby forming a rotor 2 for a flat motor. Thus, the heat generated at the air core coil 12 is efficiently diffused through the material 11. |
