Abstract
An inner rotor brushless motor is miniaturized, flattened and made lighter without reducing motor performance. A rotor and a stator are enclosed inside a sealed case (i.e., a sealed space) assembled by covering an attachment base with a cup-shaped bracket. A motor substrate on which a motor driving circuit is formed is provided in a gap formed in an axial direction between (i) the rotor and the stator and (ii) a base portion inside a bracket opening of the bracket.
