I'm just wondering about how you are going to distribute the magnetic flux along each stator with that kind of shape.

It is evenly distributed by the stator magnets being equally strong of the same size and polarity.

Do you have a means of testing the strength of the magnets that you buy, to verify that they are the same strength? If there are slight variations in their strength, will that matter to your design? If it does matter, can the design be changed, to allow for the magnet position to be adjusted, to compensate for the slight variations in strength?

I've read somewhere at http://www.fieldlines.com that same size magnets that are nominally the same strength, often have slight variations.

If necessary I'll buy a gauss meter and measure every single magnet to match them best possible.

Hi Honk!

I just read you're already ordering the magnets...
I can recommend a manufacturer in Germany for you. Neotexx is the name of the company. I ordered some custom manufactured magnets from them some time ago, and they did a great job for a reasonable price, despite the fact that I ordered more uncommon ring sizes and quite small quantities. Also they were very quick and replied to my email within 2 days, as far as I remember. If the dimensions of your magnets are not too big, I think they will be happy to help you. I emailed with a certain Jessica, I didn't remember his surname, but she was helpful. So if I were to order custom magnets once again, I would sure to send a request for this company.

Good work on your design, I am sure it will run nicely!

Magnet suppliers

Manufacturing neodymium magnets seems to be quite a hi tech business, a reason that most suppliers only offer standard sizes and small manufacturers buy in custom shapes, sizes and advanced qualities.

Quote: Machining
<Since neodymium magnet material is prone to chipping and cracking, it does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant.The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust. <

Another Chinese manufacturer with Qc and advanced tech is:
