But I started with a bigger magnet area and evey time I decreased it the torque went up.....Miles said:Arlo,
I think you need to increase the magnet area, not decrease it.........

I used a winding scheme from powercoco but maybe I need to wind it in a different way?
No making them thicker made more torque and making them higher N value made more torque as well.major said:Arlo1 said:But I started with a bigger magnet area and evey time I decreased it the torque went up.....Miles said:Arlo,

Looks to me like you're running on reluctance torque and the magnets are basically air gaps.
Yes sketchup. I have modified the magnets so many times in femm they have become ugly. The 6061 is in phase c I never changed it to the copper because phase c is not energized.Miles said:Arlo,
Was that drawing created in Sketch-Up, or something???
You seem to be using a mix of solid slot 6061 and Copper wire (10 turns)?
First attempt.......Miles said:What happens if you only have a small gap between the poles (about the thickness of the magnets) and also take away the upstand of back iron at this point?
254mm id (10 inches) 5 inches long.Miles said:Is the stator inside diameter 200mm?
What is the stator length?
I don't have your kind of money man lol. How much $ we talking? I really want to make a PM motor!jonescg said:Sounds like you are building a radial flux motor of the same dimensions as a half-decent axial flux motor. With liquid cooling it might just work
Oh, I might not need to build my own motor for the CRX - I was in touch with Evo-GKN and they said they will sell small numbers to any firm who has intentions to buy many more in the future. So if we can get a consortium together we can make the AFM140 the motor of choice for AC conversions. Then place a big order
An AFM240-4 in your machine should rip nine colours of shit through the competition

What don't you understand about winding it? It gives you the winding pattern on the exPowerCroco site. Assuming you're going for a single layer winding, the coilspan is 15 slots - 5 slots per pole per phase - two iterations.Arlo1 said:I think this will help me understand how to wind it.... I think?
There is 2 more of the Cranes this motor come out of standing behind work..... I could make a 15 inch long stator if neededjonescg said:I'd love to turn an induction motor into a PM motor, and a nice big diameter one too.
