摘要： Disclosed herein is a swing-arm type linear d.c. brushless motor, wherein at least one coreless type armature coil such as an air-core armature coil is arranged on the inner wall of a linear motor body and a field magnet is formed by magnetizing a magnet member with a single pair of N/S poles so as to permit the generation of thrust in a predetermined direction face to face with only one active conductor of said at least one armature coil and which does not contribute to the generation of reverse thrust. The field magnet is opposite through an air-gap in the axial direction to only the active conductor portion, and is supported relatively and swingably through the air-gap. It is suitable for use in small, economical and high-speed magnetic head positioner mechanisms more useful in small-capacity magnetic disk units and the like and capable of performing position detecting, feed control, etc.

摘要： A laser scanning motor includes a coreless flat brushless motor disposed in a rotatable polygonal mirror having polygonal outer mirror surfaces. A light beam applied to the polygonal mirror is deflected by controlling the rotation of the coreless flat brushless motor. Poles and a bearing holder of the coreless flat brushless motor in a rotor assembly are formed of a plastic magnetic material. When manufacturing the laser scanning motor, the poles and the bearing holder are formed simultaneously by filling the plastic magnetic material in one operation, and then firmly securing the poles and bearing holder to the rotor assembly.
