ABSTRACT:
A rotor for in-out electric motor having a shaft coaxial with its stator, ferromagnetic portions external to the stator and a cup-like shield which rigidly connects one end head of the ferromagnetic portions to one transversally extended head of the shaft, the head being at least peripherically incorporated in and made rigid with a cast metal component forming a part of the shield and which is rigid with the ferromagnetic portion. A process for producing the resulting rigid assembly is provided wherein the coaxiality of the shaft and portions is ensured. Also there is shown a mould for casting the cast metal component.
