A stator for use in a brushless motor having a rotor, comprising: a stator yoke having a first surface, and a second surface opposite said first surface; a first printed substrate fixedly mounted on said first surface of said stator yoke; a second printed substrate fixedly mounted on said second sur

A stator for use in a brushless motor having a rotor, comprising: a stator yoke having a first surface, and a second surface opposite said first surface; a first printed substrate fixedly mounted on said first surface of said stator yoke; a second printed substrate fixedly mounted on said second surface of said stator yoke, said second printed substrate being provided separately from said first printed substrate; means for controlling driving of said brushless motor, said motor driving control means being mounted on said second printed substrate and electrically connected thereto; and a plurality of drive coils mounted on said first printed substrate and electrically connected thereto, an end of each of said drive coils to be connected to said motor driving control means being directly connected to said motor driving control means and being connected directly to said second printed substrate, wherein said stator is formed with at least one notch through which a part of said drive coils passes and through which said end of said coils is directly connected to said motor driving control means, and wherein said yoke is smaller in diameter than said first printed substrate so that said part of said drive coils does not contact with said stator yoke.
