Hello,
I'm doing a motor conversion and am going to mill my rotor very soon.
so i made teas cad drawings.
the magnets are 9mm x 9mm x 50mm and there are 8 of them on the rotor
In this topic i read that one must divide 360 degrees by the number of slots (24 in my case).

so as u can see in the drawing i skewed my magnets at a 15 degree angle (looking from the end of the rotor)
the 2 lines i got from that angle are used to place the magnet's.
The center of the magnet at the ends is placed on these line's.
c the picture
Have i dun this right?
Another question is: what is the idea behind skewing?
I know its to prevent cogging but is it like, when the flux "pulls" 3 or so stator slot's then its..?
Hope u get what i mean.
And another thing I'm pondering about.
I can put my magnets in/on the rotor two way's
One way i get the most flux on top of the magnet
The other is when i rotate the magnets 90 degrees i get the most flux on top of the Pease of rotors between the magnets.
There might be a difference because the magnets will not be as close to the stator as the rotor pleases will.
I will test the two options anyway but what do u think??
