Abstract (en)

[origin: DE4443045A1] The blower (50) arranged in a combustion chamber has a drive motor fixed to the blower housing (5). The motor, e.g. a collectorless external rotor motor, is connected to a blower electronics arranged on a printed circuit board. The circuit board includes openings (6) for drawing the air toward the electronics carrier (57) which is fixed to the stator (60) of the motor. A circular aperture (69) is provided between the inner edge of the PCB and a bearing carrier tube (52), to pass the air from the circular chamber (67) to the centre of the blower wheel.
