<p><P>PROBLEM TO BE SOLVED: To provide a blower motor capable of efficiently dissipating heat generated from the entire of components mounted on a substrate. <P>SOLUTION: The blower motor has a structure in which a rotor R and a stator S are housed in a motor case, a motor substrate 9 having a motor drive circuit formed thereon is disposed in a space Q formed in an axial direction between the rotor R/the stator S and an opening bottom 2b of a bracket 2, and a heat-generating component 16 mounted on the motor substrate 9 abuts on the opening bottom 2b of the bracket 2 via a heat dissipation member 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
