An electrical machine (20, 48) comprises a first stator (22) and a second stator (24) spaced from the first stator (22), at least one of the first stator (22) and the second stator (24) including a guide arrangement (26, 50). The electrical machine (20, 48) 5 also includes a plurality of rotor elements (30, 46) located between the first stator (22) and the second stator (24) and cooperating with the guide arrangement (26, 50) for movement relative to the first stator (22) and the second stator (24). Adjacent rotor elements (30, 46) cooperate with each other so that the rotor elements (30, 46) form a rotor and at least one of the rotor elements (30, 46) includes a coupling element (32) 10 to transfer force to or from the rotor. Each rotor element (30, 46) includes a first support surface (30a) which faces towards the first stator (22) and defines a first air gap with the first stator (22), a second support surface (30b) which faces towards the second stator (24) and defines a second air gap with the second stator (24), and one or more magnets (34) mounted on each of the first and second support surfaces (30a, 15 30b) in the first and second air gaps. c-4 |
