摘要： An electric machine comprises a closed chamber (22A, 22B) with a wall (26) and enclosing a stator (30), a rotor (32) and a first fluid (F1) and a heat exchanging unit (10) stretching from the chamber through the wall to a fluid transporting passage (24). The heat exchanging unit comprises 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 (F2), a first fluid propagating unit (38) 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.

摘要： A modular crawler for inspecting a confined space that can be the air gap of a rotating electrical machinery has a main function module to which drive modules and other function modules that depend on the confined space configuration can be connected. When the confined space the air gap between the rotor and stator of a rotating machine the crawler can be used for operations such as visual inspection, wedge tapping and maintenance. The main module has cameras and on board electronics and can also have a tether to communicate with equipment located outside of the confined space, send video to that equipment and receive commands from an operator of the crawler. The drive modules have tracks that ride on the stator slots. The removable spacers between the modules are adaptive to fit the configuration that the track rides on. The other function modules provide certain other functions.

摘要： A missing stator slot wedge (10) in an electrical machine can be detected by analysing a current spectrum of the machine in a high frequency area. A current spectrum is provided from a current measurement, and values of the current spectrum in the high frequency area used to determine whether a stator slot wedge (10) is missing or not. The conclusion can be based on values of a relative current amplitude IdB or on presence of certain harmonics in the high frequency area.
