Abstract
A two-pole permanent magnet A.C. machine employs one set of permanent magnets disposed with their magnetic axes parallel to the axis of rotation of the rotor and a second set of permanent magnets disposed so that their magnetic axes are oriented radially. This arrangement allows for significant reduction in flux leakage from the machine rotor and an increase in the power density of the machine.
