Patent attributes
Disclosed is a brushless motor which allows easy positioning of an air core coil and facilitates quick assembling of the coil because the air core coil is positioned by fitting an air core portion of the air core coil to bosses formed in a coil plate. Moreover, since no jig is required for the positioning of the coil, the positional precision of the coil can be stably attained, thereby enhancing the positional precision of the coil. Furthermore, although the positioning of the coil becomes difficult as the coil is reduced in size, the present invention is capable of easily coping with the thinning and miniaturization of the coils, i.e., thinning and miniaturization of the motor. In addition, the thinning and miniaturization of the motor can also be attained by arranging a circuit board and a coil plate in parallel to each other.
