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 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 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, 30b in the first and second air gaps.
