Abstract :
This paper contains the analysis of a new flux reversal machine (FRM) configuration, designed for low speed (below 150 rpm). The machine consists of two stators, of which the outer one is fitted with a three-phase fractionary winding and the rotor carries alternate polarity permanent magnets placed for heavy flux concentration. The inner stator is slotted, but passive. The results of the finite element analysis show high torque density. Through skewing the cogging torque can be improved.
