An axial flux machine (100) is provided, in which the rotor (104) is cooled via air cooling, provided by impeller blades (140) located on the opposite side of the rotor (104) to the stator (102). An impeller cover (142) covers the impeller blades (140) such that air channels are defined between adjacent blades. The air channels have an air inlet (146) at an inner radial portion of the rotor (104), and an air outlet (146) at the outer radial extremity of the impeller blades (140). As the rotor (104) turns, the air is drawn through the air channel from the air inlet (144) to the air outlet (146). The motor (100) may be enclosed within a housing (120), in which case air ducting (150,152) may be used to guide air to the air inlet (144), and from the air outlet (146) to the outside of the housing (120). |
