A primary member for a linear induction motor is disclosed comprising a frame having a pair of spaced parallel frame members, a core located between and supported by the frame members, and a motor winding carried by the core. The winding includes a plurality of turns each of which includes a pair of parallel portions supported located in slots in the core and which are interconnected by end windings projecting beyond opposite sides of the core. Each end winding has direction-reversing knuckle portion. Side cover assemblies extend along either side of the core to cover the end winding. Cooling means are provided, a first set of which are located between the frame members and a second set of which are located laterally outboard of and to either side of the frame members.
