Can you make a brushless motor with "axial" cores and magnets, rather than radial? Answered

Picture of

In the picture, the black discs are magnets, the copper cylinders are coils, and the acrylic disc spins on the central shaft.

Well yes, but you'd need to add a 12 slot commutator or drive it as a brushless DC motor.

*misread you typed that as 'OR' statement,

I saw "it would need a comutator to run it as brushless dc"...kinda threw me off.

It doesn't need a commutator, it would (want) need to run on 3 phase, an even number of magnets and an odd number of poles divisible by 3.

Not quite sure what you mean, but the pictured arrangement is fairly easy to do. If you mount them differently but the magnets still pass the coils in a similar way it will still work.
