Determination of optimal geometrical dimensions is performed taking into account the superheat tem perature and with the use of computer investigation of parameters. After a number of transformations, we obtain2m a n 02 m c n 02 m a m c + + ( ) 2 4m a n 02 m c n 02 m a m cm a m c , = n e2 = n 01 = n 02 , and τ T = The smaller n e2 , the higher temperaturewhere m a , m c , and n 02 are dimensionless coefficients and 0.0043 and 1.063 are temperature coefficients (from reference data). Numerical values of m* are given in Table 1. Calcu lation diagrams of dependence m*(m a , m c ) ( Fig. 1) show that the values of m* increase with the increase of values for the dimensionless coefficients (m a , m c ). The variation range for coefficient m* is 1.35-3.88. Values of this coefficient are necessary for determination of optimum ratios of geometrical dimensions.Numerical values of n e2 are given in Table 2. These data allow the range of variation of n e2 upon variation of m* and τ 2 to be determined. Calculated dependences n e2 (m*, τ 2 ) show that coefficient n e2 decreases with anA* m* τ T 192m* 0.0043 1.063 τ 2 + ⎝ ⎠ ⎛ ⎞ , = increase in temperature, while it increases with an increase of m* (Fig. 2).For maximum values of m a and m c , the n e2 values are rather great, 10-16. These values are unacceptable.Abstract-The analytical expressions for optimal geometric ratios and parameters for an ac stabilizer with regard to superheated temperature windings, as well as the expression for the optimal geometric dimensions and parameters for a given values of ampere-turn windings are obtained. The analytical relationships between temperature excess, geometrical parameters, and sizes of windings are established, allowing viola tions to be avoided of the principle of proportionality and provide a given superheating of windings. Deter mination of the reliability of the calculated ratios is carried out. Algorithms for calculating the ac stabilizer are developed.
