The rotor of a permanent magnet motor includes a stack of laminations. Each lamination is located with respect to a shaft using a key with a tangential fillet. Each lamination also includes a set of lightening holes having a shape designed to minimize hoop stresses and thereby increase the maximum permissible operating speed of the motor. Furthermore, the tightening holes are aligned with the key to minimize interactions of the respective stress concentrations.
