STRUCTURES OF A ROTOR AND A FERRITE CORE OF A MOTOR, PARTICULARLY CONCERNED WITH FORMING A PERMANENT MAGNET, A FERRITE CORE, AND A CENTER FIXING MEMBER IN ONE ENTITY

摘要

PURPOSE: Structures of a rotor and a ferrite core of a motor using a permanent magnet are provided to stabilize an output and to improve the efficiency of a motor by forming trapezoidal permanent magnet, a ferrite core, and a center fixing member in one entity. CONSTITUTION: A structure of a rotor of a motor using a permanent magnet includes a trapezoidal permanent magnet(101), a ferrite core(102), and a center fixing member(201). The trapezoidal permanent magnet is fixed by the ferrite core cooperating with the center fixing member. The trapezoidal permanent magnet, the ferrite core, and the center fixing member are formed in one entity.
