Fan-motor assembly for producing pulsated air flow to ensure cooling of e.g. air-conditioning units of passenger compartment of car, has lid fixed on support-casing to define watertight case for covering motor housing

摘要

The assembly (1) has a ventilation duct comprising a part forming a volute-casing (2) and a part forming a support-casing (3). The support-casing includes a motor housing adapted to receive an electrical motor and/or a receiving housing adapted to receive a control module. A lid (31) is fixed on the support-casing and/or the volute-casing so as to define a watertight case for covering the motor housing and/or the receiving housing. The support-casing includes a peripheral vein surrounding the motor housing and/or the receiving housing.
