Abstract :
The moving magnet type actuator is developed as a new type galvanometer scanner, and its scheme and basic characteristics are shown. The characteristics of the actuator vary depending on values of its design parameters. To improve its torque characteristics, a combination method of 2D finite element analysis and multivariate statistical analysis is applied to estimate the design parameters. Its application to the higher order curve, such as the cogging torque curve, is described in detail. Some models designed by the present method are shown, and also effective parameters for torque form design are clarified
