Synchronous Electrical Concentrated Coil Machine

The present invention herein refers to a synchronous electrical concentrated coil machine or otherwise called with tooth coils. In one of its embodiments the synchronous electrical concentrated coil machine comprises: a plurality of teeth positioned on the stator; a plurality of concentrated coils wound around said teeth, suitable for constituting at least one cycle; a plurality of inductor poles; characterised in that the difference between the number of said plurality of poles and the number of said plurality of teeth of said at least one cycle is two times less in absolute value than the number of the phases; the electrical angle acf between the first coils of successive phase-cycles is acf= (Ndcf + v/Nf) 180 DEG , where Ndcf is the number of teeth per phase-cycle, Nf is the number of phases and v is the difference between the number of said plurality of poles and the number of said plurality of teeth of said at least one cycle; and the phase associated to said first coils of successive phase-cycles and the winding direction of said first coils of successive phase-cycles are determined by the phasors separated from each other by an angle equal to said electrical angle ac f of the phase sequence of the number of phases of said machine.
