Abstract (en)
[origin: EP0905382A2] An electric blower for a vehicle. E.g. a blower for supplying a secondary airflow into the exhaust system of an IC engine, has a lightweight impeller rigidly mounted on the metal shaft of the electric motor (11) using adhesive. The inside bore of the impeller hub is grooved (13) to hold strips of adhesive. The grooves can be straight or meandering and have a width typically 0.05 mm. No other fittings are required to secure the impeller. Several impellers can be mounted on the same motor shaft.
