Abstract
The present invention relates to a rotor of an electric machine for use in an aircraft. By forming the shaft of the rotor such that it performs, at least partially, the function of the back iron, components of the rotor can be combined. Further, by forming the rotor components in this manner, an internal shaft with an increased diameter can be used to provide a rotor with greater stiffness than equivalent prior art devices.
