Abstract
A linear electric machine includes a mover and a stator. The mover includes permanent magnets, and the stator includes a ferromagnetic core-structure and windings for conducting electric currents. The linear electric machine includes support structures on both sides of the ferromagnetic core-structure and supporting the mover to be linearly movable with respect to the stator in the longitudinal direction of the linear electric machine. At least one of the support structures includes a support element arranged to keep the mover a distance away from solid metal constituting a frame-portion of the support structure. The support element includes material whose electrical conductivity is less than that of the solid metal. As the mover is kept the distance away from the solid metal, eddy currents induced by the moving permanent magnets to the solid metal are reduced.
