<p>What is described is a support for a rotation sensor (12) in a motor-impeller unit (1) of an electric fan (3), of the type which includes a motor support mounting (7) which can be fixed to an outer wall (5) of a scroll-shaped casing (4) of the fan (3), the rotation sensor (12) being designed to interact, in use, with a magnet (13) rotating integrally with the motor shaft. The support comprises a seat (16) for removably retaining an electronic circuit card (14) including the sensitive part of the rotation sensor (12), and removable snap-fitting means capable of interacting with a profile of a through hole (11a) formed in the mounting (7), in such a way that the support is retained removably on the mounting (7), thus ensuring the correct positioning of the rotation sensor (12) and the rotating magnet (13) relative to one another.</p> |
