Abstract
In order to improve a rotor for electric machines, in particular for machines of high rotational speed, having a rotor core and a rotor shell comprising a binding made of fiber-reinforced plastics radially supporting the rotor core such that the rotor shell is supported on the rotor core essentially over the entire surface and with an essentially uniform surface load, it is suggested that the rotor core has an outer shell surface with a small cone angle on which the rotor shell is supported with an inner shell surface having the same cone angle, and that the rotor shell has a protective layer between the inner shell surface and the binding.
