PURPOSE:To attenuate a vibration and to reduce a noise by bonding a vibration damper to a platelike stator yoke. CONSTITUTION:A flat opposed type brushless motor is composed of a rotor made of a permanent magnet 1, a rotor yoke 6, and a rotational shaft 5, a stator made of a planar stator yoke 2, and a drive coil 6, and a housing 4. In this case, a silicon rubber sheet 7 is bonded to the yoke 2. Thus, an axial force is generated in the coil 3 by a magnetic flux of the vertical direction of the rotational shaft of the magnet 1 and a current flowed to the coil 3, the yoke 2 is elevationally deflected, and the vibration is attenuated by the sheet 7 to reduce a noise. |
