  • Patent number: 8164903
    Abstract: The present invention relates to a clamping member for pressing power components (9) against cooling surfaces of the cooling flanges (7) of a housing, particularly for receiving an electronic circuit. The clamping member comprises a housing frame (13) having at least one receiving chamber for the cooling flange (7) and the power semiconductor (9) to be contacted with the cooling flange (7), the receiving chamber being surrounded by the frame walls (14a, 14b, 15) of the housing frame. A pressure element (17) is disposed between a frame wall (14a, 14b) and the power component (9) disposed opposite thereof, or the cooling flange (7) disposed opposite thereof. A separating gap, into which an expanding element (18) can be introduced on one side non-positively and/or positively such that the power component (9) is pressed against the cooling flange (7), is provided between the pressure element (17) and the frame wall (14a, 14b).
    Type: Grant

  • Patent number: 7402925
    Abstract: A stator for an electric motor, in particular for an external rotor motor, includes a laminated stator core which is provided with a stator winding and having a connecting arrangement, which is arranged on one end side in the region of an end winding of the stator winding, for the purpose of electrically connecting winding wire ends of the stator winding and connecting wires of a temperature monitor connected upstream of the stator winding. The connecting arrangement has an insulating switching disk which covers the region of the end winding, in particular in the form of a cap. The temperature monitor is held in the switching disk in an integrated manner such that, on the end-winding side, it rests between the Mater winding and the switching disk such that it is in thermally conductive bearing contact with said stator winding.

  • Patent number: 7101157
    Abstract: The present invention provides a high-pressure blower comprising a fan arrangement which includes a fan, and a fan housing for conveying working air. An electromotor drives the fan via a motor shaft to provide motor self-ventilation by generating a cooling air stream flowing through the motor due to a cooling wheel driven by the rotor. A wall section separates the interior space of the fan housing accommodating the fan airtight from the interior space of the blower accommodating the electromotor so that the cooling air stream flowing through the electromotor is separated and independent of the air flow of the working air conveyed to the fan.

  • Publication number: 20040096339
    Abstract: The present invention provides a high-pressure blower comprising a fan arrangement which includes a fan (82), and a fan housing (83) for conveying working air. An electromotor drives the fan (82) via a motor shaft (72) with means for motor self-ventilation by generating a cooling air stream flowing through the motor by means of a cooling wheel driven by the rotor. A wall section (70) separates the interior space of the fan housing (83) accommodating the fan (82) airtight from the interior space of the blower accommodating the electromotor (2) so that the cooling air stream flowing through the electromotor is separated and independent of the air flow of the working air conveyed to the fan (82).
