ABSTRACT:
Ventilation devices, in particular for electric motor drives regularly comprise a fan wheel (1), which is driven by a shaft via an electromagnetic induction coupling. In order to reduce the complexity of manufacture, a stack of magnetic sheets (2) is cast in the aluminum hub of the fan wheel (1). Thus, aluminum also assumes at the same time the function of a damper winding.
