Abstract
An electric machine (10; 100) comprises a rotor (14a, b) having permanent magnets (24a,b) and a stator (12) having coils (22) wound on stator bars (16) for interaction with the magnets across an air gap (26a, b) defined between them. The bars and coils are enclosed by a stator housing (42a,b; 102, 142a, b,146) that extends between the air gap and defines a chamber (52; 152) incorporating cooling medium to cool the coils.
