I seem to remember converting my Student to single phase (rather than buying it done)
and so should have the original three phase motor as I rarely throw anything out, does this look like it came out of a roundhead Student, 3hp and 1420 rpm sound right, what about the pulley?
I don't recall the pulley on my Student Mk2 being that small but it was a while ago. It was a multi-Vee though, also the armour-clad wiring looks similar.
thanks, I do think it is the original, I have a pile of motors removed from various conversions, now I have three phase they will slowly be reinstalled,
