Well I don't know. There are no contacts, it's brushless. I tried putting a 4MFD capacator accross the line, and it amplified the numerous small sawtooth waves along the wave in between the peaks. They diminish as load increases.
I'm guessing that the large dip which occurs near the peak of each wave when under load represents the "dead spot" in between poles, but I'm not sure. Just a guess. The dip increases as load increases.

Actually if you look at the "jig" in the leading edge of both the positive and negitive wave forms you realise that those are not harmonics. They are occuring at the same point in each wave, with no evidence of there being an other half. In fact the "crap" appears to have the same period as the "primary" period.
I would guess there is somethng wrong in the contacts
