ABSTRACT:
Method of and apparatus for cooling the spinning units of open-end spinning machines driven by individual high speed electric motors. A cooling air flow is separated from the technological air flow, such cooling air flow being introduced into the housing of each unit in the space between the rotor of its motor and the spinning rotor connected thereto and dividing into two flows. One such flow travels between the stator and rotor of the motor; the other flow travels within the unit housing radially outwardly of the stator of the motor.
