Abstract
A miniature fan arrangement has a fan (10) including an electronically commutated drive motor (21), a first circuit board (52) associated with said motor, and a fan housing (30). The fan also has a mounting part arranged radially outside the fan housing (30), and has a membrane (32), made of an elastic material, that elastically connects the fan housing (30) and the mounting part (34) to one another. A second circuit board (54) is arranged between the mounting part (34) and the fan housing (30) and is electrically connected to the first circuit board (52). The structure provides space for additional motor control components, particularly in small-sized motors.
