dc brushless motor with PCB is a good example of soft collaboration, which makes the Hackaday community so powerful. At Hackaday, we are very grateful that the new project is based on our past featured projects. It’s great to be able to look back and see what motivates people to learn other people’s works and take them to a new level or a new path.
Bobricius said his design was inspired by the tiny PCB dc brushless motor. At present, his articles are few, but it seems that his dc brushless motor will be used to drive a small robot. Like his inspiration, the dc brushless motor has stator coils etched into the base PCB. Bobricius also abandoned the original 3D printing rotor and chose to use stacked PCB materials to make the rotor, cutting out 5mm neodymium magnet. We like to use the same material throughout the motor, which also increases the possibility of stacking the second stator on the other side of the rotor, which may be helpful in mechanical and electrical aspects. Nevertheless, the prototype still seems to retain its own style. There are also some significant improvements, such as increasing the number of stator coils from 6 to 8, and increasing the overall size of the dc brushless motor.
