I've very recently realised that current generation needs to have the magnetic field removed somehow.
Maybe you've 'polarised' the field that now assists the stepper motor instead of resisting, hence the speed up.
It drags with a direct resistive load. But speeds up when hooked to a transformer with the same resistive load on the secondary. It happens because the stepper can output well over 2 kHZ.
The resonant frequency of the secondary matches the frequency, so the output shifts 90 degrees. Thus eliminating lenz drag.
