Insert Rotor into Dies: The Weight of the Lamination Stack

The range of size and weight of the lamination stacks for copper rotors should be similar to stacks for aluminum rotors. Figure 8.1.1 shows estimates of the weight of lamination stacks for a range of motor sizes. These data are taken from motors produced in Europe, North America and Asia.
