<p>The device (1) has a motor (15) arranged outside an intake air flow, and a turbine (18) directly coupled to a shaft of the motor. A channel (24) surrounds the motor and is in communication with an outer air at a case (2) and with a depression zone inside the turbine. The channel is arranged to permit air circulation around the motor for ensuring the cooling of the motor. Suction orifices (20, 21) and an intake air deflection unit (26) are arranged in a manner to direct the inlet air in the case by the orifices towards inlet of the turbine.</p> |
