PCB stepper motor is designed for direct drive wheel for swarm robots

I am inspired with great project https://hackaday.io/project/39494-pcb-motor
Instead of printed rotor I am using PCB rotor (3 layers of 1mm PCB and 5x3mm magnets)
middle layer rotor PCB have 1mm smaller diameter and making rim for simple rubber
ring tyre

Board can be easy configured to unipolar or bipolar mode

- 4 layer 40 turns per coil !!!

Very nice.  Did the usual board shops accept it as a single 100x100mm PCB, or did they charge you for "multiple designs" ?

  Are you sure? yes | no

dirtypcb accept this

Amazing! Can you run it on steps? so you can have a mechanical display! What about adding a second board on the opposite side of the rotor with coils in one board placed in between the coils on the other board, like a hamburger with coils for buns and magnets as the meat.

untested now, I need redesign coils to connect opposite coils, now they are hard wired under board. I had hamburger plan but Chinese bearings are very bad, so for test i connect one board only.
