The invention relates to a motor housing for an electric motor with a stator as well as to an electric motor with a housing, whereby at least one multifunctional opening is arranged in the lower housing section and whereby electronics can be arranged in the housing, characterized in that, in order to cool the electronics, the multifunctional opening has a baffle by means of which an air flow can be directed towards the electronics, and, as an alternative, it has an offset on the side facing the upper housing section in order to mechanically connect the stator to the lower housing section.

The invention relates to a radial blower, with at least one axial air inlet port (1) and with a radial air outlet port (2). The radial blower has a housing subassembly and a fan subassembly with an electric motor (3) and a fan wheel (4). The housing subassembly has at least one holding part (5) arranged in the region of the axial air inlet port (1) for supporting reception of a carrying part (6), and two shell parts (71, 72) releasably connectable to one another. The holding part (5) is fastened between the shell parts. The electric motor (3) of the fan subassembly is an electronically commutated direct current motor. Control electronics (19) are arranged in a terminal box (13) for the reception of motor connections (12). The terminal box is fastened, to the underside of a lower shell part (72) of the housing subassembly.

Radial blower

The present invention relates to a fan blade for axial fans with a blade body comprising an inner inlaid part and an outer blade shaped part partially enclosing said inner inlaid part. The outer blade is made of a material of lower rigidity than the inlaid part. The inlaid part is constructed as a substantially flat metal part adapted to the shape of the blade body and in the fan blade base region has an unencapsulated smooth fixing section.

Fan blade

An electric motor, in particular an external rotor motor, comprising a stator which is attached by means of latching elements to a motor carrier using a plug-in joining operation. The elastic elements for isolating vibration are arranged in the connecting region between the stator and the motor carrier in a way that the stator is indirectly connected to the motor carrier by means of the elastic elements.
