ABSTRACT:
A supporting member is fixed to the moving element of a toroidal type linear motor, the support member being maintained a predetermined distance from a stationary element to maintain a predetermined annular air gap between the stationary and moving member. The supporting member may comprise a plurality of rollers which are rotatably provided on the top and bottom of the moving element, the rollers being so arranged as to be radially spaced from the stationary element. The distance between the rollers and the stationary element is less than the distance between the stationary and moving elements.
