  • Cooling arrangement for an electromotor
    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.

  • Electromotively driven blower and cooling arrangement for an electromotor
    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).
