Parametric motors have many excellent features compared with ordinary motors, and are anticipated to have many practical applications. Because of several nonlinear phenomena, however, motor operation is complex. To make such motors more practically useful, we investigated the stability of the parametric oscillation and the motor design. Methods for improving the characteristics of parametric motors are discussed. We determined stator dimensions and materials sufficient to stabilize the parametric oscillation, and found the optimum distribution ratio of the magnetic flux in the stator used for parametric oscillation to the flux used for motor operation.
