I have a bit of a quandry. I want to use a bldc motor to spin a magnet. That's it. The motor I have chosen is out of a PS2 slim, because of it's speed, size, and lack of vibration. It also helps that there is a spindle hub mounted on the shaft that I can mount the magnet to. What I plan to do is mount the motor in a small project box, attach a diametrically charged rare earth magnet, on it's side, to the spindle hub, apply an on/off switch and a LED indicator. To run the motor, I will install an ESC (what kind???), and possibly use a potentiometer to set a constant speed. I would like to run the whole thing on 2 AA batteries. I already built a similar model using a brushed dc motor and it works great. Now I want to step it up by making the unit more compact and increasing the rpms so I can get the most out of the 7300 micro gauss magnets.
The motor has SMT01A stamped on the base plate, E98162 stamped on the base board, and 9 wire connection points where the ribbon is soldered. Which controller do I use with this? And can I use a 1/2 watt trimmer pot (Bourns 3386 series equivalent) with 3 pins to set the speed? Also, do you think 2AA batteries would last more than 2 hours with configuration?
The reason for this project is that when you spin these magnets, it emits a measurable emf field about 4 feet out. The paranormal activity is really amplified this way!
Thanks for any help, guys (and girls).
