Some useful experimental methods for improving the efficiency of a parametric motor are discussed experimentally in this paper. One of the methods is the adoption of slits to the ring-formed stator for increasing the effective flux into the rotor. Another is the adoption of the insulation of orthogonal cores for reducing the eddy current loss. These methods greatly increase the motor efficiency.
