Hello, everyone Thanks for checking the thread. I've been trying to create a BLDC motor and I designed something random without any calculation or simulation. Unfortunately it looks like I've made a mistake and now I can't get any flux to flow from rotor to stator laminations. My intention was to create four poles with permanent magnets in the N-S-N-S formation but the core seems to attract everything with a weak magnetic force. Even when I try to get the same poles of two magnets, it still attracts the magnetic core. I used electrical steel laminations and neodymium magnets. You can find the design attached to the thread. Can someone enlighten me as to why this is happening? I suspect I created a short magnetic circuit inside the rotor and all the flux is just going from one magnet to another. I would expect at least a low amount of repelling movement but it just attracts everything, regardless of the pole's position. Oh, and one more question: If this is the case, I don't have the chance to design the laminations again so what happens if I just create a stator made out of an aluminum block? I know the eddy losses will be magnificent but can I at least get it to work? Thanks for your answers. Have a great day!
