Abstract
Process for the manufacture of rotors for asynchronous electrical motors with spherical air gaps. These rotors are designed as permanent magnets with low coercive force and comparably high electrical conductivity so that eddy currents can be formed as long as rotor rpm is different from the frequency of the rotating field of the stator while these rotors convert to permanent magnets running under synchronous conditions at rated performance. The process steps are the following:
