The PS I'm using is a cheap one with 10mA steps.
So you are blind to currents less than 10mA and v/i timings. Do you have an oscilloscope ? I don't have understanding of high-crest-factor current pulses as I am largely self taught.
Most of the members here are "Self-taught" and understand the concept of the crest-factor. The reason you don't see current drawn, is because mechanically/magnetically I have rotor magnets almost overlapping the coil cores which makes the magnetic resistance all but disappear.
No, the reason is the lack of appropriate measuring devices for measuring small pulsed currents. Coupled with a back EMF pulse at the point of magnetic equilibrium, and you have a relatively free moving rotor.
The current flowing through a coil does not reverse direction during the "back EMF pulse". What is equal "at the point of magnetic equilibrium" ? What is the inductance and resistance of your coils ? Where does your coil pulsing regime put you on this graph ? Are your threaded rods ferromagnetic ? Are you aware that even non-ferromagnetic conductive objects subjected to varying magnetic fields, will have eddy-currents induced in them, which cause mechanical braking and losses ? Are you able to plot the torque vs angle of your rotor as shown in this video ? If my sentence does not end with a question mark then you need not reply to it ...but you may comment it optionally if you wish.
