You are wrong in assuming it is an induction motor. It is a synchronous motor. It is a well known sort of motor. The rotor turns exactly at the same rate as the AC input. In an induction motor, the rotation rate is always a little under the the frequency.

The current drawn by your motor will be out of step with the applied voltage. When you put the load on, the phase between the voltage and current moves towards them being aligned in time. This is why the current is higher unloaded.more

Hi knowledgemonger,

I do appreciate most everyone's comment. However, you are wrong about me assuming that I believe this is an induction motor as this is not correct. I also know of a synchronous motors and I do agree that it operates on a same principle but they are not built like this. Multiple phases would also be a way to help prevent rotor slip. Resonance is also something that I am testing at this time but I would like to keep the coils AIR CORE.

Come to the Forum topic to see.

I am sorry if I assumed too much.

A multiphase synchronous motor still has the problem with the rotor bouncing relative to the stator field. The torque on the rotor depends only on the offset angle. This makes it still act as though it was coupled via a spring.

Adding the shorted turn creates a torque that depends on the rate of change of the offset angle and hence does the damping.

The output of you Wavetek is 50 Ohms IIRC. You can use a power amplifier to reduce this.

Hi knowledgemonger,

no problem! I know your general intent is to help.

I have an H-Bridge circuit that I'm repairing. With it I can go up to 50 volts no problem and also at what ever frequency I want. It's square wave but I can use a transformer to make it sine wave if needed. I'll make a new video once I have it working.

Stay tuned

It seems to me that it is just like a Newman motor or bedini window motor that works with zero Back emf. If i were you i would try and collect the radiant voltage spike as the coils collapses. It would be also be really awesome if you could somehow get the motor to run at the coils resonate frequency! Keep up the good work.

Hi tonysam11290,

Tony, the big difference here that most are not getting is I'm using AC. However, if you know of a Newman or Bedini that uses an AC input in a air core coil please send me the information.

About the back EMF. There is a possibility that the effect of the input power going down when the motor is under load could be because I don't collect the BEMF.

More testing will be done to better understand this effect.

Stay tuned.

This test of PMM is just great...

For those how don't like to do the math 12hz (cps)

12hz*60=720rpm,  or use algebra 720rpm/60 = 12 hz (cps)

Tesla stated further that the phenomena had a frequency of 925 cycles per second and a speed equal to Or greater than the speed of light...

Thats interesting how the current drops under load.

Try this one at low speed again with a stepper motor on the output. (like those motors that are used to position printer heads.) You'll get AC from it - just put a small bridge rectifier on each coil, and the + and - of each to a bulb.

The earth has a resonant mode at just about 7Hz. You can think of the earth, the atmosphere and the ionosphere as being sort of like a bell. When it is struck it rings. If you drive it at about 7Hz it will "ring up". Just like a bell, however, it isn't a source of energy its self. It is just a thing that responds to external energy.

Tesla wanted to distribute power using an higher resonant mode. The power would be put in at one point and tapped off where needed.

[knowledgemonger]

The back EMF will be collected in your H bridge design. When the voltage and current into the coil are out of phase, for part of the cycle the current will flow back into your DC supply from the H-bridge circuit.

The back EMF and the out of phase current are the same effect just looked at differently.
