Patent number: 9109610Abstract: 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.Type: GrantFiled: March 25, 2010Date of Patent: August 18, 2015Assignee: ebm-papst Mulfingen GmbH & Co.

Patent number: 9022753Abstract: A fan (1) consisting of an electric external rotor motor (2) and of a fan wheel (4), the external rotor motor (2) consisting of a stator (6) encapsulated with an insulating material (14), and a rotor (8) carrying the fan wheel (4) enclosing the stator (6) in a pot-shaped manner. The rotor (8) having ventilation openings in a front wall (18). The stator (6) having projecting fins (24) on a front area (22) arranged and distributed over the circumference which is opposite the ventilation openings (20). A gap (34) between a circumferential rim (36) of the rotor (18) opposite the front wall (18) and a stator carrier (38) forms a passage for a cooling air current flowing around the stator (6) during operation. During operation, the cooling air is swirled intensively between the ventilation openings (20) and the projecting fins (24) for cooling the motor.Type: GrantFiled: March 17, 2011Date of Patent: May 5, 2015Assignee: EBM-Papst Mulfingen GmbH & Co.

Publication number: 20100254826Abstract: The invention relates to a radial blower, with at least one axial air inlet port (1) and with a radial air outlet port (2), consisting of a housing subassembly and of a fan subassembly which comprises an electric motor (3) and a fan wheel (4), the housing subassembly having at least one holding part (5), which is arranged in the region of the axial air inlet port (1) and serves for the supporting reception of a carrying part (6) of a fan subassembly, and two shell parts (71, 72) which are connectable releasably to one another and divide the air inlet port (1) and between which the holding part (5) is fastened in the assembly state. In order to improve the mass/power ratio of a blower of this type, it is proposed that the electric motor (3) of the fan subassembly be an electronically commutated direct current motor.Type: ApplicationFiled: March 25, 2010Publication date: October 7, 2010Inventors: Gunter Streng, Rainer Müller

Patent number: 6028379Abstract: 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.Type: GrantFiled: December 23, 1998Date of Patent: February 22, 2000Assignee: Ebm Werke GmbH & Co.Inventors: Thomas Bertolini, Jurgen Schone, Gunter Streng, Martin Baer
