Abstract

PURPOSE:To obtain the motor having small high-frequency loss and high efficiency by a method wherein at least either of a stator core or a rotor core thereof is constituted of soft ferrite. CONSTITUTION:The stator 5 is formed with a disk-shaped soft ferrite of high permeability and small loss, and field windings 3 are arranged on the disk. The rotor 2 of permanent magnets is formed in a disk-shape, the angle thereof is divided to be magnetized in the axial direction to form plural poles, and is fixed on a shaft 1. The stator 5 and the rotor 2 are fixed respectively interposing a gap between them in the axial direction. Accordingly a yoke part formed with an iron plate is customarily fixed to the shaft 1 and is made to rotate synchronizing with the rotor in consideration of eddy current loss, but it becomes needless, and it can be formed as the stator 5 supporting the field windings 3 to simplify the structure.
