The invention relates to a stator for an electro-mechanical wave motor and an electro-mechanical wave motor including such stator. The stator includes a plurality of actuators positioned along a closed travelling path on at least a first side of the substrate. The plurality of actuators is configured to generate a travelling wave along the closed travelling path. The substrate has an outer periphery structure and an inner periphery structure and a plurality of rigid outer bridge structures and at least one rigid inner bridge structure. Each of the rigid outer bridge structures extends from the outer periphery structure and outwards and is connected to or adapted to be connected to an outer stabilization member and the at least one rigid inner bridge structure extends from the inner periphery structure and inwards and is connected to or is adapted to be connected to an inner stabilization member.
