A recent article proposed a phase-shift-modification technique for developing two-speed pole-changing windings for polyphase induction motors. In this article the author investigates the harmonic mmf content of three of the windings proposed, making use of a procedure developed and published over a dozen years ago. The results are compared with the results of similar analyses on commonly used fractional-slot least-common-multiple windings; they are also compared with the harmonics in a pole-amplitude-modulated arrangement. This analysis reveals the existence of very serious harmonic mmfs in at least two of the three phase-shift-modified arrangements proposed in the recent article, and shows the third arrangement to be much better, though still somewhat inferior to the other windings analyzed. |
