Abstract
A system has an axial field rotary energy device with a housing, an axis and a rotor with a shaft, bearings, rotor disks and permanent magnets. A printed circuit board (PCB) stator is between the rotor disks to define an air gap on each side thereof. A variable frequency drive (VFD) assembly has a VFD housing and first pads coupled to inductors to facilitate heat removal from the inductors. A concave cradle is coupled to a ferromagnetic core and has a same contour as an outer surface of the ferromagnetic core. A second pad is coupled to a rectifier module. A third pad is coupled to switching devices and has pins to align the switching devices with the third pad. Standoffs are coupled to the VFD housing to support a first printed circuit board assembly (PCBA). A second PCBA is mounted to a shield plate above the first PCBA.
