ABSTRACT:
A bobbin comprises three hollow-cylindrical sections, specifically a middle body section, and two lateral body sections. The middle body section has its diameter diminished compared to the two lateral body sections thus forming an annular recess which allows a magnet wire to be wound with an additional number of turns around the bobbin without increasing a motor size. With this bobbin structure, when the number of turns of a magnet wire is set to remain unchanged, the diameter of flanges of the bobbin can be reduced resulting in a downsized motor.
