Abstract

PURPOSE:To provide a rotor of small inertial moment and good rotation balance, by making the rotor of a field magnet of resin and shaping the rotor to fit a rotary shaft in the center of the rotor. CONSTITUTION:The rotor 8 for an outer-rotor motor or the like comprises the magnet 11 and the rotary shaft 6 and rotates in a space defined between a stator 16 and a magnetic circuit member 25 fitted on the inside of a casing 1. The magnet 11 is made of a mixture containig ferrite powder and a thermosetting or or thermoplastic synthetic resin and is shaped like a cup so that the magnet has a cylindrical wall 11a and a bottom 11b. A boss 26 having a through hole 27 is integrally formed on the central part of the bottom 11b of the magnet. The rotary shaft 6 is tightly fitted in the through hole 27. such a construction can be applied to an inner-rotor or axial- air-gap motor as well.
