Abstract
PURPOSE: To permit a motor blower to be air cooled even from the interior of shaft and eddy current to be reduced by providing longitudinal or lateral through-slits in a straight, hollow pipe shaft of motor blower.
CONSTITUTION: A shaft 1A is a straight, hollow pipe provided with longitudinal and lateral slits 20, 21. Hence, secondary air flow which is guided by air flow sucked by a fan 12 and accelerated by air flow discharged out of a housing 7 on the basis of its negative pressure as shown by the dotted line, passes through the shaft 1A to cool an armature 1 from the interior thereof. Thus the cooling effect of armature windings 2 and a commutator 4 is improved to permit a motor blower to be effectively cooled. Also, since the shaft 1A is hollow, the volume of the shaft as conductor can be reduced to lessen the generation of eddy current and the rise of temperature.
