摘要
The paper shows that Carter's coefficient gives permeance values almost identical with the true ones for narrow teeth, as established by Carter's later work, unless the tooth width is less than the radial air gap. A small increase in the coefficient is given for tooth widths down to zero. The flux-density distribution obtained by the superposition of waveforms for successive slots as in isolation, is also seen to be indistinguishable in all cases from the true waveforms for near slots, as recently established by Freeman. It is shown that the harmonic content of the ripple is conveniently expressed by a wavelength spectrum.
