what is typical car alternator inductance?
hmm, the only hint of an answer I found is in this paper: http://cdn.intechopen.com/pdfs/38166/InTech-Power_electronic_solutions_to_improve_the_performance_of_lundell_automotive_alternators.pdf; on p. 183 it says they looked at a Delcotron 22SI Type 12V-100A, and in its original configuration it is 0.1 ohm, 390uH, 6 pole pairs.
