摘要

Title of the invention Method of manufacturing a micro-blower for a respiratory assistance device The invention relates to a method of manufacturing a micro-blower (1) for a respiratory assistance device (100), comprising a electric motor (2) rotating a rotary axis (3) carrying a paddle wheel (4), said paddle wheel (4) being arranged in a volute (8) comprising the steps of fitting the paddle wheel (4) ) on the motor shaft (3); to balance the impeller (4) on the axis (3) of the motor so that the flutter is between 0 and 0.1 mm, and the static unbalance is between 0 and 20 mg.mm; and controlling the clearance between the impeller (4) and the upper volute (8a) so that said clearance is between 0.1 and 0.5 mm.
