BRUSHLESS MOTOR WITH VIBRATION TYPE CORE

摘要

PROBLEM TO BE SOLVED: To provide a brushless motor with a vibration-type core that can set an amplitude of vibration optionally without increasing cost and man-hour. SOLUTION: This invention relates to a brushless motor A with a vibration type core attached having a structure of an outer rotor type core-attached brushless motor of which one end 3a is supported by a bearing device 6 in such a way that it can freely rotate and the other end 3b is equipped with a shaft 3 fixed at the center of rotation of a rotor yoke 1, a circular core 4 arranged around the shaft 3 and the other end 3b of the shaft 3 makes a radiantly-cut shape toward an outer periphery form the fixed center of rotation of a rotor yoke 1 which is equipped with a side part 1b where a circular type magnet 2 is wholly or partially arranged in such a way that it counters with the core 4.
