Abstract
The invention relates to a radial impeller (1), preferably on an electric motor (10), especially an electric vacuum cleaner motor, with an impeller disc (8) on which are fitted preferably curved blades (2) with an outer curve (3) and an inner curve (4). Through apertures (6) are provided in the impeller disc (8). To reduce noise, the invention proposes that the through apertures (6) allocated to a blade (2) be formed on the outer curve (3).
