EMF Pump Phase 2 – Success!

by on Jan.30, 2010, under Equipment

My first attempt with the EMF Pump was a failure (in my eyes) but at least I was too far away from my logic. After posting that earlier post, Brad (founder of Spokane Paranormal) commented and offered to lend his hand! I was able to call him on the phone and roughed out a wiring diagram to wire two box fan motors in parallel. Nice that I had two laying around and was already playing with this concept, but I liked the idea of using just the fan coils (removing the shaft.. which luckily for me is really dangerous to mess around with).

At Entities-r-us.com, I found a post where Brad provided some results with using a EMF pump…

It has helped us alot in gathering evp evidence. On our first investigation using the emf pump we gathered 17 evp’s. On our next investigation we went to a place we have investigated many times. Our usual evidence yielded on average 4 evp’s. When we went back and used the emf pump we gathered 17 evp’s and 2 apparitions. It seems as though it gives them more energy. The evp’s were very clear and louder as well. Instead of gathering mostly class b evp’s, 14 of the were class a. One of them was so loud and clear you would swear that somebody had sat next to the recorder and just spoke into it. It was louder than any of the investigators throughout the whole night.

So here is my procedure, and again, I’ll add my standard disclaimer… I don’t take any responsibility for any death, injuries or loss of property. I’m just illustrating how I did this.

I used two Lakewood box fans, the kind you find at Walmart, etc. Oddly, my two fans were purchased at two different times, so the motors were different. I completely took apart the fans and released the motor from both of them. After taking apart the motor housing or cage, I removed the shaft which spins the fan.

In my case, I wanted to stick with the electronics assembly of the first motor, but I need to tie in the second motor. After the switch, I connected the same color wires to the first motor and combined the ground (black). The other colors represent speed stages with red being the high speed setting. The switch is a 3 way selector switch with off, 1, 2 and 3 speeds.

Brad instructed me to use a 3″ 110 VAC case fan (Radio Shack part #273-242) to help cool the coils. With out the fan mechanism the coils get HOT and will eventually shut down with out some cooling. This fan will be used to exhaust heat away my enclosure. Brad uses a Playstation 2 shell for an enclosure, which I really like that idea, but I wasn’t quite sure where to pick one up quickly (I needed this to be done for an upcoming investigation) so I opted to use a small tool box ($5 at Walmart).

After wiring everything and testing if both coils worked and no fires occurred I began to think about mounting the coils and electronics. Below is a photo of my coils with everything wired up, including the fan with temporary test leads.

I used my dremel tool to cut the brackets that held the motor originally in the box fan and reattached the motors to my pieces. From there, I ran to Ace Hardware and started buying all sorts of spacers, socket heads and locking nuts. I used spacers to raise the coil mounts about a 1/4″ off of the bottom of my enclosure. I also bought a square U-Bolt to sit between my coils. I would use this bar to zip tie some of my wires to keep things tidy and away from the hot coils. I decided to mount the fan to the top of the lid and used a forsenor (spelling) bit to cut the large vent holes at the top. Thinking about additional venting I added some smaller holds to both sides of the enclosure.

For the potentiometer switch I made a template based off of the original fan housing (basically two notch cuts above and below a circle cut). My switch popped into that just like how it did in the original box fan chassis. I bought a little cooler knobby and attached it with a set screw.

Here is a photo of the EMF pump opened.

Here is a shot from above with the EMF closed.

Here is a better view of the front showing the knob to fire the unit up.

Again, I would like to thank Brad from Spokane Paranormal for helping with this build! I really do appreciate it, and I’m excited to start using this on upcoming investigations with Tortured Souls Investigations.

    Coming up soon is a comic about the EMF pump… it’s quite funny! Just thought you ought to know.

    Great Website. I may add you to my links list. Feel free to reciprocate!

    Thanks!

    “Comic about the EMF Pump”?? Interesting. I added your link below.

    Thanks!

    What do you power it wih?Some times you go on investigations and don’t have power to hook into.The emf pump looks good but its to bulky.The ones I have seen are no longer then a box of 12-9 volt batteries.

    It’s powered by 110VAC.. so power cord. It’s not meant for non-powered environments. I’ve seen those non-powered jobbies.. but you have to ask how much EMF that could pump based on batteries.

    Thanks for the comment.

    I’m looking for a diagram on how to build a battery powered emf pump.When we do investigations we don’t always have power.I have seen the battery powered emf pumps in action.If I could get hold of a circute diagram I would build it myself.

    We like to use a generator with low dbs instead of converting everything to battery power. How did this work out for you?

  • Sharita Desormo

    The 3 phase electric power is common way of alternating current transmission and it is a type of polyphase system and is the common way used by electric power distribution grids to distribute power. That looks like the right 3 phase alternator I’ve been looking for.

  • Skullkeeper

    Nice build, what EMF levels do you get out of it?

  • John B.

    Thanks for posting this information.

    Based on your information, I’ve played around with a couple of box fan motors without their shafts. I see the EMF readings are pretty high, but I also see the temperature starts to get up to where I’m not comfortable leaving it plugged in for a period longer than around five minutes or so.

    After this, I started investigating other fans. I found that cheap $14 bathroom exhaust fans (again, without the shaft) from the local Lowes building supply appears to generate even higher EMF readings. Again, temperatures became high to where I was concerned it might get too hot and become unsafe.

    I saw where there would be no getting around using a fan motor without the fan blades, but I was worried about the noise factor. I kept looking at those AC powered EM pumps built in the largest plastic radio shack project box and wondered how they were getting high EMF readings and keeping the noise levels low. The only thing that I can figure out is that they simply have an AC powered 4.5 inch quiet fan with a switch and that’s it. Period. The quiet fan must be generating the high EMF readings and there doesn’t appear to be enough room within the box for much of anything else.

    Next week, I plan to order an AC powered 4.5 inch quiet fan (around $40) and try it out.

    As far as a battery powered box, I played with 12 volt DC fans from old computers. I built one in a project box with 8 D-batteries, but the readings are still a little weak. If the AC powered version is a Sherman tank, then the battery powered version that I have is moped. I am going to shelve the DC powered version until I can build and test out the quiet AC version, and then I see if I can improve the DC powered version.

    I figure that I would pass this information forward since you were kind enough to post your version. Let’s keep the exchange going.

    UPDATE:
    I think that I was able to get past the heat issue and not use any fans within a box. I purchased 120 volt AC door bell transformers from my local home center (Lowes or Home Depot). I can fit several within a Radio Shack project box, but I decided to only use two within a large project box. I believe that I could have placed four or more inside. These generate higher EMF readings than the small 12 DC volt computer fan motors with their shafts removed, but I do need an AC plug. The 12 volt dc motors were generating readings of 3 to 25 on my EMF meter, and the AC version with the transformers were generating readings of 20 to 110 on the same meter. Although I need to test this AC powered unit for several hours for heat, I do like what I have seen so far without the need of a fan. I can’t recall if you posted any EMF readings from your box fan unit, so the EMF readings from mine might be a little lower, but I feel a little safer without the heat and the noise of the fan.

    I still would like to figure out how to make a higher powered DC unit that doesn’t use AC power, but I’m looking into a couple of ideas.

    UPDATE:
    I tested my version of the EM Pump for several hours without any heats issues. In fact, the project box that the transformers are in seemed to remain cool to the touch the entire time.

    Next, I introduced the pump to the group and they were eager to try it at a location that had been investigated once before. Their success was next to nothing the first time they went there, but this time the pump appeared to have helped. After setting up all of the equipment and then exiting the home, we allowed the home to sit and rest for around +/- 15 minutes *we also did this every time the teams switched up). We then went in and performed an investigation. Nothing seemed to have occurred the entire evening while we were in there (normal human hearing, our sight or video, or touch/feeling). This evening one of the leaders just happened to check one of the digital recorders tonight and found several instances of walking, singing, and some voices; and this all inside the home while nobody was within the house. The rest of the evidence still needs to be examined, along with the recordings from that same recorder, but the group leader is extremely happy with what the pump may have contributed towards collections. If there appears to be more EVP evidence, I will be building more units of the box that I described and built. I may build one with four transformers inside to see how it compares with the one that only had two; especially since the box remains cool to the touch. Just wanted to add this to my previous postings.

    Buying a programmable line voltage thermostat can be made easier by shopping online. Information, reviews, and recommendations help to ensure that consumers are buying a thermostat with the right features for their family. You need to make sure you get the right programmable line voltage thermostat for your application. Maybe I can help.

    The first EM pump that I made using two doorbell transformers were made with the one chime versions. EMF readings would start about 10 to 12 inches away.

    With the second EM pump, I used two chime transformers with even stronger EMF distance results that started about 18 to 22 inches away. No high heat involved with the transformer.

    I found that there are three chime transformers rated at 40 watts and go for the price of $15 to $25 dollars a piece. I am seriously thinking about either building a third version or gutting the first EM pump of the transformers and replacing them with the three chime, 40 watt versions (unless I can find a four chime version). Based on what I have seen with moving from a single chime transformer towards a two chime version and seeing increased EMF results, I feel somewhat sure that I should either see an increased distance as well, or better strength all the way around the project.

    I still haven’t given up on a battery operated version of an EM pump, and I have a few strong ideas on how to build one from off the shelve parts, but I can’t see me doing this until later in October or sometime in November. I might be wrong but I do not see a battery version giving off the same levels of EMF readings like an AC powered version does. We’ll see.

    I just had to leave a post noise of fans and heat. I used a small under the counter flourescent ballast with a switch and used rheostat for dimmer switch for lite to boost and control emf levels. For using outdoors while inconvenient and heavy use a dc to ac inverter and car battery but will work.

  • Jason L

    To John B,

    I’m going to order the 120vac chime transformers today. How do you have them setup?

    I’ve never played with chime transformers. Do they need a power supply or do you just have them connected to a power cord?

  • Robert

    I to am playing around with the box fan idea. Take your meter to a box fan you have sitting around. Take a reading in front of the fan, then take a reading behind the fan.. How big of difference do you guys get?

  • Robert

    Well.. I made an EMF pump.. I used one Lakewood fan for the pump and for exhaust, I used a smaller 12v dc Dell computer fan. The pump produces thus far 1500 mgs. And that was just from testing in a short session.

    You can get some magnet wire from eBay and wind your own coils and experiment with different cores.

    You can take various power transistors and something as simple as a 555 timer or as complex as a PIC or AVR processor and experiment with different pulses and frequencies.

    A UPS lead acid or car battery can generate enough of an EMF when it’s shorted to a short wire (no coil) to wipe clean a credit card stripe from a couple of feet away, so a properly wound coil driven with a variable frequency inverter circuit is sure to get results!

  • Enzo

    Another thing I’m insistent on trying is wrapping magnet wire around the perimeter of a room that’s known to be haunted. Anywhere from 40-50 rounds of 30-gauge wire hung from push pins along the wall near the ceiling should create a very large flux density that could be detectable from hundreds of feet away.

    Pumping it with a potential of about 5 amps at 12 volts should be sufficient. The problem is, if the spirit, entity or object attempts to draw too much energy at once, it might cause problems. It would be a good idea to limit the current or put an adequate fuse in place to the coils so it doesn’t burn something up. It would also be interesting to monitor the amount of current drawn from the coil.

    It’s not a very portable solution, but it might yield interesting results for those with the time and patience to try it out!

    Thank you, Gravatar for your posts about building the true emf generator which I am in the process of building my own. My first emf generator was the ones where as a rare earth magnetic was attached to a Samsung tray motor. I bought into the hipe that everyone was saying that this was a emf pump. Not realizing that all it was a magnetic field generator not a true emf pump. May I ask, did you wire the two ac doorbell transformers together the same way as you did with the fan motors? Is there anyway that you can provide me a wiring diagram for it? Can I place this doorbell ac transformers in say a large Radio Shack box? Will I still have to wire in a fan to cool down the transformers?
