Abstract
A spinning or twisting machine comprises at least one operating unit, which is driven by a drive motor mounted near an operating unit, at least one suction or air duct, a heat collecting jacket for a drive motor at least partially enclosing the drive motor, and at least one connecting air duct connecting the heat collecting jacket with at least one suction or air duct so that heat generated at the drive motor can be exhausted through the duct. The ventilators normally associated with the drive motors can be eliminated or reduced in output and energy consumption.
