Abstract: An electric machine including a closed chamber with a wall and enclosing a stator, a rotor and a first fluid and a heat exchanging unit stretching from the chamber through the wall to a fluid transporting passage. The heat exchanging unit includes conduits provided in a loop, containing a working fluid and equipped with evaporator channels and condenser channels, first heat transfer elements inside the chamber for transferring heat from the first fluid to the working fluid via the evaporator channels and second heat transfer elements in the passage for transferring heat out of the working fluid via the condenser channels to a second fluid, a first fluid propagating unit inside the chamber forcing the first fluid to circulate and a second fluid propagating unit in the passage forcing the second fluid to flow past the second heat transfer element.

Abstract: A method for identifying a fault condition in an electrical machine in which at least a stator or a rotor has parallel winding branches is disclosed. A measurement is carried out for obtaining a set of circulating current values between two parallel winding branches of which each winding branch includes a single coil. A frequency analysis is applied on the set of circulating current values to obtain at least one frequency component. A fault condition of the electrical machine is determined on the basis of the at least one frequency component.
