1 Development of the localized induction motor model Consider an induction machine such that the stator windings are identical, sinusoidally distributed windings, displaced by 120°, with Ns equivalent turns and resistance, rs. 24 Centrifugal Pumps Consider the rotor windings as three identical sinusoidally distributed windings displaced by 120°, with Nr equivalent turns and resistance, rr. The voltage equations are given as: vabcs = rsiabcs + pλabcs vabcr = rr iabcr + pλabcr (5) where, v is the voltage, i is the current, λ is the flux linkage, p is the first derivative operator, subscript s denotes variables and parameters associate with stator circuits and subscript r denotes the variables and parameters associated with the rotor circuits.

Meridian hydrodynamic field data in an optimized domain depending of impeller type offers the perspective of results close to reality. Sections of the calculation are equal to the number of stream lines (11 lines of flow) which means doubling or even tripling them to the case of using the graphic-analytical method of tracing the hydrodynamic field. Choice of blade area in as many variations or options initially imposed is an additional possibility to optimize the blades. From the preliminary study it is known where D2 will be located on the output edge.
