Bowman Permanent Magnet Motor Replication 2008

[CLaNZeR]

I have been meaning to knock up the Bowman Motor for a while now and realised while doing other stuff that keeps me away from the workshop grrrrrr, that I could happily leave the CNC machine running in the background cutting out the pieces, especially the Coggs as they will take a while.
So I have decided to try the Bowman Machine.

A few people have tried replicating it before and there is a excellent page at The Flying Dutchmans site that covers everything from the history of it, to the replications.

Also some great info at

Okay here is a picture of the Bowman Motor from John Bedini at

As you can see 3 Rotors and 3 Coggs.

I am using the Metric dimensions from the Flying Dutchmans site.
I tried to source Spur gears that were 90mm pitch and 45mm pitch with 70 and 35 teeth but could not find them, so first thing to do is leave the CNC machine running and mill some out of 8mm Delrin.



I am going to use 10mm Brass Rods and as usual mount them in small 3mm RC bearings to try and reduce the friction as all designs I have seen so far are using big bearings and hence more friction.

Will post progress as I go along.

Is there anymore replications out there apart from the guys that tried 4 years ago?

Cheers

Sean.

It looks like a fun project, and I love your machines. Are you running a machine shop?  My magnet wheel is doing funny things like it would spin one way for a minute or two after bump starting and then stop and spin the other way. Then it will rock back and forth until stop and then it isn't truly stopped for it just kinda vibrates or may be best called a jiggle, then I move the the parts apart to stop it. LOL It looks like I have a ways to go on mine. May be I need to get you to cut some parts out for me.

Well that was quicker than I thought, Gears all cutout.



Now onto the Rotors to hold the magnets. I do not have Alnico magnets and was going to order some till I read the following about a friend of Lee Bowman:
http://www.pureenergysystems.com/os/MagneticMotors/BMM/Bowmans_friend/index.html

He seems to being going on about diametrically magnetised Rotor magnets.



Lee Bowman Son sort of backs this up here:
http://pesn.com/2005/08/04/9600143_LeeBowmans_son/

Where he states:
He also recalls that the magnets were not the typical N-S type.  His recollection was that the "pole was in the middle".  He said his memory was not clear on this point.
Which says they are maybe Radially magnetised?

So the Rotors I am making I think I will just place holes in them and tap them out to 3mm for mounting different configs for now.

The plot thickens 

More to come

Hi AB

Well the small ones are always the fun ones, as they do not take much time and you do not get as messy hehe
Have not forgot about your Gravity design I plan to build, just need a clear run for that one.

Is there a thread with your magnet motor?, I do not think I have seen it and would be interested in taking a look as usual.

I got my own little workshop at home with a couple of CNC machines, Lathes, Drills, grinders, chopping saws etc etc. Just stuff I have collected as I have needed it.
I used to sell my CNC machines at http://www.cncdudez.com but do not have time these days.

If you need any parts that are quick to cutout and do not mind them not being cut to precision Laser tolerences  then give me a shout by all means. Have done a few bits for guys in the forums over time, but as usual it all depends on time, so do not expect a quick turn around

I had been debating about posting for it isn't finished. but what the hell, here is an unfinished photo before additions. If you would like a video send me an email. I am not sure when I may youtube it yet. So keep what you see on the video under wraps for now.
