Update,
most who have been experiencing this AUL (acceleration under load) effect may of noticed it's easier to achieve it with a higher impedance coil (more turns) then a low impedance coil and also using higher rotor rpm = higher frequencies.
Many, including myself (2 years ago) would of thought the coils Inductance was part of the effect seeing it happened with higher impedance coils.
I have now confirm (to myself anyways) that the effect is not based on the coils Inductance by testing the super low impedance coil I showed in my video.
It's inductance is 16uH with a resistance that's so low, it's unmeasurable.
With this special wounding geometry coil I can achieve AUL with the magnet rotor as low as 35Hz which is a new record for me.
The great thing about being able to achieve AUL at a lower frequency is, drastic reduction of core losses caused by eddy currents and hysteresis.
Just thought I would share my new findings
