Abstract (en)
[origin: US2005098641A1] 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.
