Abstract
A motor includes a stator and a rotor having an axis of rotation and a magnet. The stator includes a PCB having PCB panels. Each PCB panel is assigned to one electrical phase. Each PCB panel has a pair of PCB layers. Each PCB layer includes coils, and each coil in each PCB layer of a PCB panel is circumferentially aligned with a corresponding coil in another PCB layer. One coil in one PCB layer is coupled to a corresponding coil in another PCB layer with a via. A number of turns in each coil is a multiple of a number of electrical phases configured for the PCB stator. In addition, the vias that connect two coils in a pair of PCB layers that belong to a same electrical phase do not intersect coils in PCB layers that belong to other electrical phases of the PCB stator.
