ABSTRACT:
A fan has a sensor (86; 186) for sensing at least one value of the air that flows through the fan (20; 120). The fan has a fan housing (22, 24; 122, 124); an electronically commutated external-rotor motor, arranged in that housing, having an internal stator (30; 130) and an external rotor (46; 146); a fan wheel (56; 156) coupled to the external rotor (46; 146); an air inlet opening (58; 90; 158) for the inflow of air that is to be moved by the fan wheel (56; 156); a circuit board (68; 185) having a portion (66; 188) that extends adjacent the air passage opening (58; 158); and conductors (82, 84; 182′, 182″) arranged on that portion (66; 188), to which conductors the sensor (86; 186) is connected, preferably by a Surface Mounted Device (SMD) method. Premounting the sensor on the circuit board facilitates automated manufacture and reduces cost.
