ABSTRACT:
An improved rotor for an electric machine, particularly for a synchronous machine, comprising a field winding cooled to a low temperature in which the rotor includes a concentric, hollow, cylindrical support body having internal slots on its inside for accommodating the field winding so that the winding can be placed in the slots in a simple manner and the windings retained more securely therein.
