Muammer Yildiz Magnet Motor

[tinman]

the important question is what kind of physics are behind the motor action if not a scam.its either a violation of 1st law thermodynamics or 2nd law thermodynamics.im going to rule out a 1st law violation and go with the 2nd and say its some kind of assymetry in the isothermal magnetic cycle of events.a part of the magnets must be cooling down and sucking in ambient heat here.

Profitis-If the Yildiz magnet motor actualy worked as claimed,you will find that it is not breaking any laws of physic's as set by nature-only those that man has set sofar.These law's of physics set by man are far from absolute,but only what he knows today to be true.

It is not difficult to measure how many watts or HP it take's to spin a fan blade or propeller.The first thing to remember is that a fan and a propeller are two very different thing's,and opperate in different way's.A propeller is designed to produce thrust,while a fan is designed to move volume(a boat prop is a mixture of both)
The second thing to remember is the difference between a static test and a dynamice test.A static test cannot give you a watts or HP result-as nothing is moving.To obtain a watt or HP figure for a given amount of revolution's,we have to do a static/ dynamic test.

As we cant go chasing the prime mover around the lab trying to calculate speed,we need to measure wind speed only.To do this you will need a wind tunnel in which the fan blade fits into.You will also need a wind speed meter and a small set of digital scale's.The fan must fit within the wind tunnel tube with no more than a 2% gap of that of the fan diameter.The wind tunnel (round tube)must also have difuser plates to stop wind vortices forming inside the tunnel.You will also need a 1 inch square plate fixed to a knife edged arm,which has a center pivot fixed to the outer side of the wind tunnel tube.This will give you a 1 to 1 fulcrum on which your scales are attached to.You now have a means to measure wind speed and pounds per square inch of force inside the wind tunnel.This can then be calculated to watts or HP being produced by your fan blade.Once you have this and you know the rpm of your fan blade,you then have a set figure of how much watts or HP your fan blade is producing at a given rpm.If you know the watts that your motor is outputing and you now have your watts of output from your fan,you can now calculate the % of slip from your fan.You will also now know how many watts of power it take's to propell 1 square inch of a rigid material threw the air at the given wind speed in the tunnel-providing air density is the same on all test.This is done by deviding your watt output from your fan by the square inches of your wind tunnel.

Please note that the above method is for a fixed prime mover,and the fan rpm must be 20% under cavitational speed.

Quote from TK:


"I'd say 5 or ten Watts at 2600 RPM isn't too out of line. It certainly does NOT take half-a-horsepower to do it."


I read that Yildiz tried to bring a third larger demonstration model that delivered the 1/2 h.p. with him, but the Turkish Patent Office apparently prevented him from crossing the border with it.

Or we could get a manufacturer and part number off of the blade and have the info needed in mere moments.
I doubt Blade wittling is one of Yildiz skills, Being secretive in regards to the blade would be a very poor move on his part, seeing as how it is the only way he can validate his power claim ,the blade specs should be posted on the plexi box he has it all mounted in.[obviously he's not a good "trade show Man".


While some may be unaware of this loading method [propellers] few things have been researched
and tested as much as aircraft propellers .


I do like the @TinMans Tunnel tester tho ,and he points out a very big issue ..the Yildiz device that I have seen before was the Motor mounted up against a tube ,with the drive blade inside which in turn moved air thru another drive blade mounted to a small generator.........


That will definitely apply more load than the Prop in free air,and is the reason those tube measurements would be required for a good  Control .


but once again ,all that info [load calibration and test lab certification]should be posted on a little info card on the front of the demmo!


very poor show man and marketer .....

The propeller is a standard 16x10 electric airplane tractor propeller.

Sorry that I cannot get out of the bed, because of having 39 degrees of fever for 2 days.
I called YILDIZ and got the info :
The motors have a diameter of approximately 35-40 cm
The shaft is 45 cm long, 17 mm thick
The propeller stays 5-10 cm far from the motor's face

The propeller has a diameter of 40,6 cm
The codes on the propeller are as follows : 406×254, 16×10
I hope this info can help you. The propeller is just a simple one. There is no further info on it.
There may be also other propellers that are suitable to be found at the air model shops. But I don't know the way to mount them on the shaft.

I think, it's this one : http://www.zkauf.de/apc-luftschraube-16-x-10-elektro-propeller-406-x-254-in-cm-e160824977061.html

I asked him to give us info on the number of blades, their pitch, and ideally the manufacturer, make, model. A photo would be nice, too. [I've asked him to confirm that the above link is the actual blade.]
April 3, 2013; 7:40 am update: Halil sent an email last night saying that that link above is indeed the same blade he will be using.From

Looking at the photos, it appears that the prop on the demo "continuously non-running motor"  is indeed a 16 inch prop. Of course it's not possible to tell the pitch... but 16x10 is very common.

And we know how to calculate the power required to turn a standard model airplane propeller don't we?
http://www.stefanv.com/rcstuff/qf200203.html

Both pitch and diameter affect how much output power the motor must produce to turn the propeller at a given rpm. The following equation shows the relationship between motor output power (also called shaft power, or propeller input power), rpm, pitch, and diameter:

power = k * rpm^3 * diameter^4  * pitch

The factor k depends on the units used to express power, pitch, and diameter, and also on characteristics of the propeller such as the airfoil it uses, its overall shape, thickness, and so on. For power in Watts, and diameter and pitch in inches, k is about 5.3×10^-15 for an average model airplane propeller.

Well? At 2600 RPM, how much power does it take to turn that propeller? Half a horsepower? Or .... somewhat less.
