<p>An inner rotor type coreless generator has permanent magnets rotated by a rotating shaft and forming magnetic field poles, and also has armatures provided with coils arranged facing the permanent magnets. The armatures each have a coil sealed by heat resistant resin and formed in a circular plate shape having a center hole. The outer periphery of an armature, formed in the circular plate shape, is held by a heat radiative metal frame. The magnetic field poles are formed by arranging the permanent magnets in circular plate-shaped holders, in the center of which the rotating shaft is fitted, and the magnetic field poles are arranged in a radial pattern so as to face the coils of the armatures. The generator is small-sized and light-weighted, has good heat radiation ability, and has an increased power generation output.</p> |
