Abstract :
Some new techniques in the analysis and design of electric machines are discussed, namely: the time-periodic analysis of the magnetic field in nonoriented materials, taking into account hysteresis characteristics; 3-D transient analysis of capacitor-discharge impulse magnetizers; and a 3-D optimization method of electric machines considering nonlinearity and eddy currents. The usefulness of these techniques is shown by applying them to actual machines and comparisons with measurement results
