Hi another look at at trying to get a smoother high speed motor, Im using a motor out of a old large disc drive wich generates a modified trapezoid signal my idea atm is to remagnetize the rotor so it is much more of a sinewave, ive managed to remagnetize it with a different number of poles before using a few turns of wire on a iron slug wich fits neetly inside the rotor, and 2 big 450v electrolytics in series and a BIG microwsitch.
so im thinking of having more turns spread out to magnetise it with a less abrupt transition between poles, however if the magnetising current is too high it will simply clip and cuase the same result, so my next idea is to have the wire at an angle so the transition is effectivly spread out.
my question is wich would be best, to put the wire at a straight angle like a series of triangles or try and mimic a sinewave ?
the rotor has 4 pole pairs, the stator has 6 segments, with tiny segments inbetween each one, im a bit baffled as to what those are for.
although theres something like a bell ringing in my head thinking of my electric machines lectures decades ago, but all I can remember is compensating windings to stop comutator flashover, but this is brushless.
