R-Charge Window Motor

[airfource1]

can somebody sorry for me and show me the hall sensor circuit please

Hi Erfinder,

Interesting video and nice build! Your comments about bemf being somewhat "directional" are also interesting. What is the orientation of your magnets - are they all facing in the same direction?

Cheers,

Luther

Asymmetrical No BEMF Motor

Hello,

A few pics of my new 100% Orthogonal (A-Field) motor. It generates a very interesting waveform when spinning in one direction, the wave inverts when you spin it in the opposite direction....maximum BEMF in one direction...less to no BEMF in the opposite direction....

hi john am here for the first time on a forum i need some info am building a window but i need to know how many turns on the drive wire can i go without trigger wire only hall? can i use core

[jackdaddy57]

Has there been any more developed about this zero force motor. After seeing this the other day, I'm very interested about the wiring and electronic schematics. Is there anyone who can give me more info please.

Thank You,

Jack

RC Groups - View Single Post - How do you measure AMPS with a multimeter?
You can use a shunt resistor to measure current using a common voltmeter.

As Ohm's law states:

I = V/R

Where:

I = Current
V = Voltage
R = Resistance

To implement the formula, simply put a low-value resistor in series with the power or ground connection to the ESC, then measure the voltage difference between each lead of the resistor. The difference can be plugged into the formula to yield a current.

For example, a .05 ohm shunt resistor reads "0.17V" across the two terminals. We simply replace the variables with our known values and solve the equation

1: I = 0.17/.05

2: I = 3.4A

When using this though, take care that the shunt resistor is of the lowest possible value to minimize voltage losses, and by minimizing voltage losses, you are also minimizing power dissipation, as:

W = VI

Therefore:

W = I x I x R

Using this formula we can calculate power dissipation of the given resistor. Suppose the conditions of the above example, 3.4A and 0.05 ohms.

1: W = 3.4 x 3.4 x 0.05

2: W = .578W

Keep in mind that the resistor power rating of your shunt must be a higher number than your calculated dissipation at max continuous current draw you plan to measure.

Hope this helps, it will allow you to easily measure current using just a DC voltmeter.

This will help anyone like myself that keeps blowing multimeter's :-)

I just saw this video and i noticed something strange.
The leads of the portable multimeter near the circuit are connected to the VOLT measurement inputs. The setting switch is set on VOLT measurement and the screen displays the value in VOLTS.
Why are you stating that you measure miliamps and not volts with this configuration?

Hi,

The multimeter indeed shows voltage in the VOLT measurement inputs BUT it shows the voltage drop across the big heat sinked shunt resistor (placed to right side of the circuit) so the bottom line is you can see "current" draw of the circuit. If you watch the video in HD, see to it at 2:18 for the range switch setting. Hope this helps understanding.

Lester,yes this is correct.

Thanks for pointing that out Tom. I'm still getting used to the terms used here since I can't find it's meaning anywhere. I did make several window motors before but the performance was disappointing and it is only recently that I understood why, and that's reason I'm building again. A-field it is! No more ignition trigger coil this time, reeds should do the trick.

As far as I understand now and please correct me if I'm wrong, the A-field is the rotating magnetic field surrounding a single wire and if the wires are bundled together (multi-filar & multiple turns in a coil) such that the current is flowing in the same direction in all the wires, the field in a single wire repels the other adjacent fields in the other wires and as such it forms one, big, rotating A-field. Since this field has a very very short duration, the act of pulsing the coils causes several of these A-fields to form around the wire, one for each pulse, in succession, and for as long as the magnet is in close proximity to the coil it will be repelled (or attracted) to the coil. So the longer the length of the coil, the more pulses you can put into it before the magnet goes out of range, resulting in more torque. Is my understanding correct?

Thanks again Tom!

Greetings all.

I would like to try and build a similar window motor as Mr. Bedini showed in his video.
[ATTACH=CONFIG]1057[/ATTACH]
I'm planning to drive this with an SSG circuit initially, upgrade to a Bedini-Cole driver once I get it spinning. Reed switches for triggering although I did notice that there were magnets in pairs for triggering in the video, perhaps to make a very wide trigger pulse?

Just air-core coils at the moment..... and still using the same curved magnets from 5 years ago. No super-poles this time although the single magnets' poles are facing each other so that will probably help somewhat.

Comments and warnings appreciated. =)

Regards,
Lester

Lester tht looks like an a field motor, not a window motor. a WM is a rotor that is surrounded by a rectangular coil that creates a "window" shape around the rotor rectangular, square, or otherwise. it is also driven by a specific circuit, the bedini cole half or full bipolar circuit.

Hi Thanos,
I don't see what you see? While I can't tell where the leads go, I can clearly see the multimeter on the mA setting. If John were to connect a voltmeter to the output or input using a 12volt source, wouldn't we see a reading of more than 0.063 - 0.230 volts...

Mostly, I've replicated this experiment w/o much problem and very little tuning. Give it a go, it really get's the creative juices flowing.
kind regards,
Patrick

Just a question...

I have a generator coil on a stator motor that can run small loads without the mechanical oscillator changing speed or the input current going down. In the video there is the little alum battery running the stator motor. It's running at about 165 ma. The bulb is incandescent and draws about 75 milliamp. When I add the bulb parallel to the input battery the current draw goes up over 200 ma, but when I put the bulb on the output (generator coil & FWBR) the current drops from the 165 ma to about 135 or something like that. The motor RPM stays the same and the current transition shows up on the battery as it recovers accordingly. OK so I'm thinking if one coil runs a load and decreases the amount of current then, two should be better right? Anyway see what you think. Maybe Carl will like this also, he likes all the different kinds of motors.

Hope you enjoy the short clip. I took it out of the hour long video I ended up with but haven't posted.
Take care all

You guys are inspiring.
I can't tell you how much I appreciate Mr. Bedini and the rest of you here on the forum.
I have learned more from some of these discussions than years of reading and research.

That was one of my favorite Dvds as well.
Over and over and I finally started to get more than just excited.

I am wondering if there will be a source for a kit from someone who actually follows instructions...

I was delighted to find an alternative on the monopole thread.

yes there will be.

I was recently re-watching DVD 2 for the umpteenth time and noticed this zero force toroid build sitting right on the table. Tom Bearden mentioned JB has at least a hundred different builds laying around. Amazing amount of research.
