<p>A rotor assembly for an electric motor includes a plurality of laminations disposed in a stack, a tension rod (31) extending axially through the rotor lamination stack, and end clamps (27, 29) disposed at each end of the rotor lamination stack and secured to the tension rod for compressing the stack to hold the laminations of the stack fixedly in position by compression. A method of stamping rotor and stator laminations for a doubly salient electric motor from a single piece of metal includes the steps of stamping a rotor lamination out of the piece of metal, and stamping the stator lamination out of the piece of metal offset from the stamping of the rotor lamination so that a tooth of the rotor lamination stamping is taken from the gap between two teeth of the stator lamination stamping. The centroids of the rotor and stator laminations in their stamped locations in the piece of metal are offset from one another.</p> |
