A rotor for an electric motor comprises a shaft having a laminated armature stack mounted thereon. A collar is fitted on the shaft at each end of the stack, and an epoxy resin coating coats the stack and bonds the collar to the shaft to fix the stack in position on the shaft. The collar may be formed by a cylinder which is split along its length and has an internal diameter equal to, or slightly less than the shaft diameter, so as to form a space between the shaft and collar and facilitate entry of the epoxy resin. |
