Abstract

The present invention is directed to a flat brushless motor utilizable as a warning in a portable communication device. The center of gravity of the rotor assembly is displaced from the center of rotation so that, by the rotation of the unbalanced rotor assembly, vibrations can be generated and the. By elimination of an eccentric or the like for generating the vibrations, a manufacture in a flat and compact size, as well as a reduction in the number of component parts, can be attained.
