STATOR COOLING SYSTEM OF VALVE-TYPE ELECTRICAL INVERTED MACHINE

摘要

An electrical machine of inverted type comprising a casing, a rotor with a fan mounted therein, an air heat exchanger enclosed inside the machine casing outside the rotor and comprising coolers with fins, a stator mounted inside the rotor and fixed to the housing. The proposed machine is characterized in that the fans longitudinal axis of the air heat exchanger is directed at such an angle relative to the machine longitudinal axis that the air flow direction formed by the rotor rotation in running on lateral plane of fan fins coincides with the direction of air flow formed by the fan mounted in the rotor.
