Abstract

For cooling external-rotor motors as used for driving fans and blowers, an air current (17) is produced along a hollow inside a fixed post (3) inside the stator (2) of the motor so that heat is taken up by the air current from the inside of the stator and transported to the end (6) of the hollow post (3). At this end of the motor there is a plate (7), normal to the post (3) of the motor and designed for producing a radial air current in a space (9), i.e. because of the suction effect of the main outside air current (16) produced by the blower. The radial air current supports the flow of air in the hollow post (3), and heat is thereby removed from the stator. Heat pipes may also be used to remove heat from the stator. <IMAGE>
