Now that the disclaimer has been made for the mentally challenged and litigious out there.................... In 30 minutes I cannibalized, stripped, and made a homemade demagger, including photographing it. Took longer to post. Anyway, here goes............ Here's the fan in a freezer that I am cannibalizing. The picture is sideways because the freezer is in my junk trailer bound for the landfill. Here's the removed motor assembly on the bench. Remove fan blade......... Remove motor from bracket........ Remove rotor end cap bolts, then remove rotor caps...... and finally the rotor, leaving field and laminates and wires. Shown here are the wires from the motor (black), and wires from a simple power cord (white). Strip ends...... twist fine wires together on each wire...... without twisting the two wires together, insert into wirenut cap and twist clockwise, letting the cap twist the wires together. Twisting the two together before placing cap on it would make a poor connection, and the cap could fall off. Do the other two wires the same way. Here's the wires connected from a power cord (white) to the motor (black). Very simple. This picture shows an e-clip stuck to my magnetized screwdriver tip. The next pic shows the screwdriver placed into a smaller hole in the laminate. It is held in place, then the unit is plugged into the wall. The magnetic field can be felt in the handle. Slowly remove the screwdriver in a straight line from the laminate and keep withdrawing in a straight line from the hole, then about a foot away, unplug unit. Voila! Screwdriver tip is no longer magnetized, and no longer attracts the e-clip. It should be noted here that I used the smaller holes in the laminations to quickly demag the screwdriver. Using the bigger hole takes several passes, but the smaller hole does a faster job. I happen to have a manufactured demagger, from Jules Borel that I use. To magnetize an object, they say to place the object in the hole, in the center, and plug the unit in. Wait a few seconds, while holding the screwdriver steady inside the hole, then unplug, and remove the screwdriver. It should now be magnetized. Sometimes,depending for various reasons, you may have to do it several times. Same for demagging. To demag, once again, place screwdriver fully into hole, plug unit in, then slowly withdraw in a straight line till about a foot away, then unplug unit. Hope this all helps and makes sense....doc Post script: I did not use a momentary contact switch in this unit for clarity, so you would not have to always plug and unplug the unit. Be sure to unplug unit from outlet when done so it does not overheat.
