Abstract
A fan has a sensor () for sensing at least one value of the air that flows through the fan (). The fan has a fan housing (); an electronically commutated external-rotor motor, arranged in that housing, having an internal stator () and an external rotor (); a fan wheel () coupled to the external rotor (); an air inlet opening () for the inflow of air that is to be moved by the fan wheel (); a circuit board () having a portion () that extends adjacent the air passage opening (); and conductors () arranged on that portion (), to which conductors the sensor () is connected, preferably by a Surface Mounted Device (SMD) method. Premounting the sensor on the circuit board facilitates automated manufacture and reduces cost.
