Thane Heins Perepiteia Replications

Right, this is weird. I've assembled a makeshift motor:  Even though the magnets and coils are facing the same direction I would have thought I would be generating DC when I take the drive power off, but I'm generating AC.  From what I can see, the coils are pushing power in both directions.

I'm now confused

Keep in mind that the induced (generated) voltage is directly related to the direction of movement. When the magnet is approaching the coil/core the voltage is of one polarity...when the coil/core is directly over the magnet there is zero induced voltage... when the coil/core is receding,(leaving) the voltage is of the opposite polarity (to the approach).

Thanks for the clarification.

This is the motor so far:  http://www.youtube.com/watch?v=3X8rlB5kOOI

I have the multimeter connected to the start and end of the coil series and when I apply the 18v battery it reads 10-11v.  When I release the battery it then reads 5v.  Couldn't tell you if it's any good or not.  But I wouldn't be surprised if I could get it to over 2000rpm on the 18v, I keep chickening out because I think the magnets'll fly out.  And trust me, at that speed I don't think i'd like to hang around if they do shoot out.

can anybody explain (or refer me to previous posts regarding) HC COILS and INNER AND OUTER HV COILS

Hey, runs pretty good! But yes, always the danger that the magnets will fly out. One reason why I prefer axial designs,

Thanks Minde for the Bobbin info.

Now i need to procure, some I laminations with the following characteristics.
High magnetic flux permeatability & low eddie-hysteresis losses.
As mr T's laminated "fingers"
Anyone knows any shop on line?

ps: I bet I_ron knows
