Abstract

This invention relates to a device for cooling an electric motor for a turbo-fan unit. The motor has a shaft (16) which extends through the motor (10) and which supports a turbo-fan impeller (20) which is placed outside a shell (11) belonging to the motor. The turbo-fan impeller rotates with a speed above 50.000 rpm thereby creating a primary air flow which via an outlet (35) escapes from the turbo-fan unit. The turbo-fan unit (20) comprises means by means of which a secondary air flow is created which at least partly cools the electric motor and which from one or several cooling air inlets (28,30) separated from the primary air flow <IMAGE>
