Steorn motor v2: Measuring the current lag in the toroidal coil and fine tuning

JLN has posted a short video on optimizing coil switch timing.

Hi All,

Please see the following video of the new magnet arrangement and how it causes a violent cogging effect due to the intense magnetic attraction of the magnet pairs to the toroidal coil's cores. The rotor is very hard to turn slowly by hand.

That must be the strongest magnetic rotor ever built
Let us see at what current it frees itself from the core.

I'm guessing from the steorn-patent curves, the current will probably be large when the rotor is stationary but lower current will be needed at high speeds, to free it.

And I agree with the above post, you need to replace those metal L-shapes with plastic or wood, because they will only cause a drag.

I'm wondering what does this mean ?

@ramset,

I got my 6 hours sleep tonight. Then I wanted to see if my new motor will run.
And it does, but I keep blowing those Hall sensors, so I will try out either a pickup
coil or a Read switch.

Groundloop.

Show schematic and Hall effect part number perhaps we can fix the blowing out of HE,  I have never blown a HE unless I was switching too much current in its output to down line electronics.!!

This very interesting experiment shows that, while the rotor approachs to the toroidal stator coil, the current lag increases dramatically due to polarisation of the ferromagnetic core and to the increase of the magnetic viscosity. This experiment shows also a good method to find the optimal angle where the stator coils must be energized. If the toroidal coils are energized at this point, the current will be minimum and thus the energy spent in the motor optimized...
