Effect of parameter changes on the performance of shaded-pole motors

Using a method of analysis previously published by the authors, computed results are presented of changes of some of the performance characteristics of a shaded-pole motor due to varying its major design features, namely, the number of main-winding turns, the total-pole arc, the shaded-pole arc, the shading-ring conductance, and the resistance and skew of the rotor cage. Such results enable the choice of a preliminary design which is not far removed from the optimum design, and therefore allow the latter to be obtained with a minimum of trial computation.
