Sorry Low-Q.
I will not perform this test. The motor is just to hard to build to be disassembled again.
And I don't know how you managed to simulate this type of motor using no stator magnets.
Without any stator magnets there is no stall torque. And without stall torque there is no thrust forward.
It's the releationship between Stall Torque at Zero RPM and the Zero Torque at Full RPM that
determines the capacity of an electric motor.

Quoted from another site: http://www.gizmology.net/motors.htm
Torque vs RPM
For permanent magnet DC motors, there is a linear relationship between torque and rpm for a given voltage.
The maximum torque occurs at 0 rpm, and is called stall torque.
The minimum torque (zero) occurs at maximum rpm, reached when the motor is not under a load, and is thus called free rpm.
The formula for torque at any given rpm is: T = Ts - (N Ts ? Nf)
where T is the torque at the given rpm N, Ts is the stall torque, and Nf is the free rpm.

Wouldn't it be smart to make a module based motor, where the two magnet arrays are separate assemblies you can put in and take out as you whish? With the tools you have, that should be as easy as scratching your head. Or are you afraid the motor shows up more efficient without all the magnets? (I'm just questioning - I hope it's ok )

What tools? I don't have any tools to easily make any mechanical setups.
When I need specific stuff like this I ask my laser friend to cut the stuff from drawings I provide.
And most of the times I have to wait for several month before he has the time to cut it.
If I pay his company it would of course just take a couple of weeks to get it. But I can't afford this.

Regarding the motor, I know for sure that you don't get any torque if you remove the stator magnets.
So I won't perform this test. I just don't have enough time to play around. I must focus on the project.
And you don't realise the forces within this type of magnet spiral motor. There is no way to remove any
module based stator spiral in a simple way once assembled. Each stator spiral is attracted towards three
of the rotorheads at 261kg (575lb) of force. I wouldn't be able to move the module, no matter how hard I tried.

Btw, it's always OK to ask or make suggestions.

I look forward to see the result

Good luck!

Today I performed some more Solenoid vs NdFeb matching tests to see how much the sticky spot is weakened
by the applied parallel magnetic field. The more the stickyness is weakened, the more the motor output is increased.
My powersupply could only feed 180W into the coil but this was enough to slash the stickyness by one third.
I intend to use pulses at approx 600-700W and this should soften the tough sticky spot a lot more.
Perhaps as much as three quarters weaker if lucky. These test were made using an ordinary steel core.
Later when the High Permeability Ni-alloy core is processed and ready to be wound I will get even better results.

I'm slowly but steadily making progress in the FBDISSM development.
The Flip-Field Flux-Booster controller schematic is finished and ready to be cadded into a PCB layout.
This new controller will deliver heavy duty currents (60amps) to the Solenoids at very fast rise times.

Edit: Just to clarify things about the power consumption. The solenoids will only run at 600W for a very short time.
        I have calculated the average ON time to about 20-25% for all six rotorheads in one revolution.
        This will result in each Solenoid dissipating 120-150W. They will be fan cooled be using inserted copper fins to conduct heat.

ain't you afraid paul sprain will steal your attract-repel idea and then patent it?
looks to me like this would be an easy task and then you can kiss your motor goodbye!
