Abstract
The fan (20) includes: a drive motor (26), a shaft (28) coupled to the drive motor (26), a wheel (30) supported by the shaft (28), a support structure (24), including: an outer body (38), a duct (40) including a sidewall (48), the duct (40) defining, with the outer body (38), an inner space (50), and a housing (46) situated in the inner space (50) and in contact with the sidewall (48), the housing (46) defining an inner volume, a ball bearing (32, 34) inserted between the shaft (28) and the support structure (24), and a sensor (36) for measuring a mechanical parameter representative of the dynamic behavior of the bearing (32, 34), the sensor (36) being positioned in the inner volume defined by the housing (46).
