Electromagnetic brake assembly for a vehicle with a wheel 2 comprising a hollow section 4 and a rim 6, the rim comprising a first portion 9 comprising an electrically conductive material, such as silver or copper, and a second portion 10 comprising a plurality of a permanent magnets and a stator 12 comprising at least one electromagnetic coil, (15, fig 3) located within the hollow section 4 of the wheel 2, wherein the stator 12 is moveable between a first position in which the at least one electromagnetic coil 13 is inductively coupled to the first portion of the rim 9 when the wheel 2 is rotating relative to the stator 12, and a second position in which the at least one electromagnetic coil 13 is inductively coupled to the second portion of the rim 10. The stator may also be in a third position, in which at least one electromagnetic coil 13 is inductively coupled to the first portion 9, and a different electromagnetic coil is coupled to the second portion 10. |
