ABSTRACT:
An improved fan useful for ventilating applications in motor vehicles features a modular structure, which facilitates quick replacement of any components likely to fail. A first module (110) is intended for permanent installation on the part that is to be cooled. A second module (110) is configured for quick engagement to and disengagement from the first module. The second module preferably comprises a hub (22; 362), an internal stator (60; 332) mounted on the hub, and one or more struts (74; 344) connecting the hub to a cylindrical casing part (76; 336) which surrounds but is spaced from the outside of the fan wheel (46; 348). The struts form a lattice (112) which can be easily grasped for swapping out the second module when repair or replacement becomes necessary. The fan has a Hall sensor (50) and a control circuit (156) which regulates fan speed according to PWM (Pulse Width Modulation) or DC voltage signals (164) supplied from outside and has means (186; 244) for generating a fault signal in the event of a fault state, and for sending the fault signal out on a control line (90).
