PRINTED CIRCUIT BOARD STATOR WINDING ENHANCEMENTS FOR AXIAL FIELD ROTARY ENERGY DEVICE
摘要:
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. An axial field rotary energy device is disclosed, for example, the device including a printed circuit board (PCB) stator having PCB panels. Each PCB panel can include conductive layers. Selected ones of the conductive layers are coupled to plated vias that extend from one major surface of the PCB stator to an opposite major surface of the PCB stator. In addition, each major surface of the PCB stator can have a layer of a dielectric material that completely covers ends of the plated vias.
