Abstract
An electromechanical transducer, such as a motor (1), comprising a rotor member (4), a stator member (3) having an electrical winding (8), and isolating means (11, 9, 16, 12) isolating at least a part (18) of one of the members (3) from the other member (4), and cooling fluid in direct contact with said part (18) and isolated from the other member (4). The stator member (3) is preferably cooled by pumping liquid past it, whilst the rotor member (4) is isolated from the liquid. The rotor member (4) preferably operates in an evacuated chamber (48). A pump (5) is preferably provided to pump the cooling liquid around a cooling circuit (47, 6, 5, 47, 42).
