PURPOSE:To attain thinning by introducing stator coils arranged in a petaline manner into petaline holes slightly larger than the stator coils mounted to sections of a chassis oppositely faced to the stator coils. CONSTITUTION:Stator coils 5 are disposed on a stator yoke 4 in a petaline manner. Holes 9 in size slightly larger than the size of the stator coils 5 are formed where corresponding to the stator coils 5 on a chassis 8, and the stator coils 5 are housed. The stator yoke 4 and the chassis 8 are superposed and bonded, and faced oppositely against a magnet 1 for a rotor 2. Accordingly, length in the direction of a shaft 3 is shortened only by the thickness of chassis, thus allowing thinning. |
