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

A fan () consisting of an electric external rotor motor () and of a fan wheel (), the external rotor motor () consisting of a stator () encapsulated with an insulating material (), and a rotor () carrying the fan wheel () enclosing the stator () in a pot-shaped manner. The rotor () having ventilation openings in a front wall (). The stator () having projecting fins () on a front area () arranged and distributed over the circumference which is opposite the ventilation openings (). A gap () between a circumferential rim () of the rotor () opposite the front wall () and a stator carrier () forms a passage for a cooling air current flowing around the stator () during operation. During operation, the cooling air is swirled intensively between the ventilation openings () and the projecting fins () for cooling the motor.

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.

The present invention relates to an electric motor having a high degree of protection against the ingress of foreign particles and moisture, in particular an electronically commutated external rotor DC motor, having a stator (), having a rotor () and having an electronics housing () which extends transversely with respect to the motor shaft () and accommodates in its interior () a printed circuit board () having open-loop and closed-loop control electronics and commutation electronics. In this case, connection openings () are located in a base () of the electronics housing (), connection elements (), which connect the stator () and the printed circuit board () to one another, passing through the connection openings (), and a seal () seals at least the connection openings () in the base () of the electronics housing () through which the connection elements () pass. The seal () comprises a plate like partition wall () which is arranged on the base () of the electronics housing () and serves the purpose, on the one hand, of physically sealing the electronics housing () and, on the other hand, of sealing the gaps in the electronics housing ().

Electric motor having a high degree of protection against the ingress of foreign particles and moisture

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.

Electric motor with screwless plug-type mounting

The present invention relates to an arrangement for the vibration-isolating mounting of an electric motor (2) on a support part (6) via an essentially disk-shaped support element (12). The support element (12) has a motor-holding section (24) for connection to the electric motor (2) and a support-holding section (26) for connection to the support part (6), and the two holding sections (24, 26) are connected via elastic, web-like connecting pieces (28). The connecting pieces (28) are designed such that the two holding sections (24, 26) are elastically movable relative to each other three-dimensionally in all directions in space, specifically axially, radially and tangentially, over a certain movement play. The support element (12) has integrated stop means for the three-dimensional limiting of the elastic relative movements of the holding sections (24, 26) and/or an additional mass (110) to influence the vibration behavior.

Arrangement for the vibration isolating mounting of an electric motor

The present invention pertains to a stator for an electric motor, composed of a stator core assembly (2), stator windings (3) and, arranged at one end of the stator core assembly (2), an interconnecting arrangement (4) for the stator windings (3). An interconnecting arrangement (4) features an insulating part (9) with slotted chambers (11) in order to accept electrical connecting leads (12), insulated from each other, in order to interconnect the wire ends (7) of the stator windings (3).
