WELCOME ALAN,

IF YOU GO BACK A FEW PAGES YOU WILL SEE THAT THIS QUESTION HAS BEEN POSTED A NUMBER OF TIMES BY A CRIMINALLY INSANE COMPULSIVE LIAR WITH A SPLIT PERSONALITY / BI-POLAR DISORDER.

Alan, the ratio Pout/Pin is the efficiency of the system. Typical standard induction motors have an efficiency of about 95% - the systems under discussion here have an efficiency of typically less than 30%.

Is it just me or did everyone just feel a cold breeze?

My new coils suck, although I have not yet tested them with the rotor directly on the motor, I have been running it through the isolation axle with a steel rod in the pipe and it now accelerates and not awfully but nothing impressive either. (I also switched the rotor to a single stack)

Worse yet I am finding that my home made motor speed controller while nice due to it's cheapness sadly even as the lowest level it's giving me about 2,600rpm currently which is possibly due to using a larger motor and possibly a smoother stator config.

I am not sure if the answer is to make a better speed controller or to put paying Luc off further and sink all my dough into a Variac, I guess I'll research ways to make the speed controller more variable first.

ET TU BRUTUS?

I know the feeling, remember I hated the whole concept of an aether
I was looking for correlations in devices finding few until I could not help but see the aetheric correlations, how the devices all only made sense with an aether.

To you the aether might as well be bubblegum, to me the aether might as well have been a turd so your cognitive dissonance should be a lot less than mine was.

Oh, and I successfully modified my power controller, too easy!
But now I'm going to spend some time to make my device safer!

Carpet

I bet that's a word no one expected me to start a message with.
I have been looking at ways to make my device safer, quieter and more secure.
And the noise was getting to me and so I grabbed a mat of the floor and put it under the motor and coil and Viola far far less noise and vibration! amazing how much.

Things may even stay on the table now, and I bet it increases efficiency by putting less energy into sound but even if that's not so the increased quiet will be appreciated by all.

Also make a separator so the coils can't come too near the rotor (something the same size as the minimum safe gap that can be placed between the base of the coils and the base of the motor)

And I'm going to copy Thanes electrical board things seen in thew latest vid.

Thats just the cool rationale of perceived truth. All the electrical data posted so far shows a less than 30% electrical system transfer efficiency.

Thane has been focusing on the Acceleration effect in terms of Torque for use in automotive transport,, e,g the buggy!
Imho the low electrical transfer efficiency is secondary to his current goal of increasing Drive Torque.

However, without gathered experiment torque data, there is no way of knowing the Total System Torque, nor establishing system torque transfer efficiency during mechanical loading ..

The sooner Thane gets torque data and/or his buggy together, the better.
Real world experiments require real world testing.
I bet Thane's just itchin for a cut loose drive in the buggy anyhow!.
