<p>Device, such as a device for compressing fluids or for refrigeration, comprises a rotor (1) in a rotor chamber (2) in a stator. The rotor performs in operation a cyclic movement which movement comprises a rotational component (φ) and a translational component (T). The rotor has means for generating a rotor magnetic field and the stator has means (3) for generating a stator electro-magnetic field which extends in the rotor chamber. In operation the stator electro-magnetic field creates a force field applied to the rotor which field is synchronous with the movement of the rotor, the force field comprising a rotational as well as a translational component. Preferably the stator field is generated by electro-magnets which can be magnetically coupled and decoupled.</p> |
