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, 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.
