Stator for a rotating electrical machine, uses grooved outer and inner faces on two concentric cylinders forming stator to provide passages for cooling fluid to circulate round stator

摘要

The stator for a variable reluctance machine is made from two concentric cylinders (2,3), the interior cylinder (2) having a grooved external periphery and the outer cylinder having a grooved internal face, with the grooves facing each other to form closed passages (10) for circulation of a cooling fluid.
