Abstract
brushless doubly-fed machine is receiving attention as a contender for several niche applications, In some cases, the speed ranges of these applications appear to be more readily met by judicious selection of t he pole-pair numbers of the stator phase windings, In order to compare different proposed pole-pair configurations and to help in the develo pment of specific designs, a general analytical model, in both dynamic and steady state forms, is presented, This model supersedes previous analyses which are restricted to the 3/1 pole-pair combination of earl y laboratory machines, The new model is also completely valid for both positive and negative control voltage sequences. The increased modeli ng flexibility enables sound estimations of the drive converter rating s, the reduction of which is the keg to the economic advantage of thes e machines, An example of the correlation of the performance predictio ns and test results encourages use of this new model.
