A primary member in or for a linear induction motor of a kind in which at least part of the working flux passes generally transversely of the motor; the primary member has a magnetic core structure terminating in at least two transversely spaced ends, and a two-layer energising winding of which the winding conductors extend generally transversely of the primary member to pass adjacent the ends of the core structure. The winding conductors are angled where they cross the gaps between the ends so that in operation the travelling magnetic fields produced by the energising winding at the two ends are substantially in antiphase with one another. |
