    摘要: A flat brushless motor utilizable as a warning means in a portable communication device such as a pocket bell. The flat brushless motor is such that the center of gravity of the back-yoke (5a) is displaced from the center of rotation so that, by the rotation of the unbalanced back-yoke (5a), vibrations can be generated and, by the elimination of a weight or the like for generating the vibrations, the manufacture in a flat and compact size as well as the reduction in number of component parts can be attained.
