A method of manufacturing a rim assembly for either a rim-driven-fan for an electrically powered fan engine or a rim-driven wheel device powered by means of electromagnetic motors. The method comprises: providing a rim 26, wherein the rim is a bladeless rim; mounting a plurality of magnets 24 around the rim; and attaching a non-magnetic retaining band 34 in tension around the plurality of magnets. Attaching the retaining band in this way may pre-stress, or pre-load the rim. The term “bladeless” is used herein to mean a rim without blades or spokes attached to it. By attaching the non-magnetic retaining band to the magnets mounted around the bladeless rim, the residual stresses at rest are reduced. Therefore, the blades can be designed differently and their weight can be reduced by using a reduction in material and even different materials,
