Abstract:
1. An axial-flux electrical machine comprising a rotor-stator module of the machine, the rotor-stator module including a stator having first and second axially spaced stator portions, and carrying windings of an electrical conductor thereon, a rotatable member which extends at least between the stator portions, along the axis of rotation of the machine, and which is rotatable with respect to the stator portions, and a rotor mounted on the rotatable member, the rotor being located adjacent and between the stator portions, and including a series of circumferentially-distributed magnets thereon wherein the rotor-stator module includes a first cooling structure in contact with the first stator portion, the first cooling structure including channels therein for conveying a coolant fluid therethrough, and a second cooling structure in contact with the second stator portion, the second cooling structure defining channels therein for conveying coolant fluid therethrough.
