A rotating electrical machine includes a two-phase rotor having two non-rotating solenoid-wound rotor coil assemblies and two interleaved pole assemblies. Each pole assembly is magnetically coupled to its respective coil assembly and rotates together with the machine shaft. Each pole assembly has four or more elongated pole pieces, two of which couple with one pole of a coil assembly and two of which couple with the other pole of that coil assembly. An exciter circuit independently controls the power variables provided to the rotor with respect to the stator to provide a variable-speed, variable-frequency (VSVF) motor system or VSVF generator system. The exciter energizes the solenoid-wound rotor coils with biphase AC electrical excitation, to produce a radial, rotating magnetic field at the pole pieces.

[ What is claimed is:] [1.]1. A rotor for use in an electromechanical machine functioning as either a motor or an alternator, the electromechanical machine having a rotatable shaft along an axis of rotation, the rotor comprising:a first and a second phase assembly, each of the first and the second phase assembly comprising:a cup-shaped core concentric with the rotatable shaft;a coil disposed inside said cup-shaped core and solenoid-wound with respect to the axis of rotation to provide two coaxial poles at a single end of said cup-shaped core, said coil and cup-shaped core non-rotating and fixedly mounted within the electromechanical machine; andtwo pole-piece assemblies positioned so that a magnetic field from said two coaxial poles is coupled to said two pole-piece assemblies without direct physical contact, said two pole-piece assemblies fixedly mounted to said rotatable shaft, each polepiece assembly having two or more pole pieces elongated in a direction parallel to said axis of rotation;wherein said two or more pole pieces of said first phase assembly are interleaved with said two or more pole pieces of said second phase assembly.
