Abstract
An outer rotor type motor provides a rotor of an outer rotor type motor with an optimal and simple structure that can be assembled easily. A rotation shaft is supported in a bearing housing and a stator is formed of a field winding. A rotor disposed outside the stator to house the stator therein, has a yoke surface on which a permanent magnet for performing a magnetic interaction with the filed winding of the stator is installed. The rotor rotates around the stator. A shaft bushing connects the rotor and the rotation shaft. The shaft bushing to be fastened to a central portion of the rotor is formed to have a polygonal shape to prevent a loss of a rotary power of the rotation shaft and has an insulation member for an electrical insulation of the motor.
