1. A system, comprising:
an axial field rotary energy device having:
an axis of rotation;
a rotor coaxial with the axis and having a shaft, rotor disks, and permanent magnets on each rotor disk;
a printed circuit board (PCB) stator located axially between the rotor disks to define an air gap on each side of the PCB stator between the PCB stator and each of the rotor disks;
a housing having two housing sections with at least one of the housing sections having an inspection port oriented radially, relative to the axis, and aligned with the PCB stator and the air gaps and the system further comprises:
a variable frequency drive (VFD) assembly comprising:
a VFD housing having:
a concave cradle coupled to a ferromagnetic core, the concave cradle has a same contour as an outer surface of the ferromagnetic core, and the concave cradle facilitates heat removal from the ferromagnetic core;
a switching device pad coupled to switching devices to facilitate heat removal from the switching devices, the switching device pad having pins to align the switching devices with the switching device pad, and spring clips to retain and apply uniform pressure to the switching devices; and
a PCBA mounted to a shield plate comprising:
lights that visually indicate a status of the VFD;
mounting brackets coupled to the VFD housing and configured to adapt to axial field rotary energy devices of different sizes;
a flexible conduit connects the VFD housing to the axial field rotary energy device; and the VFD further comprises:
a main cover coupled to the VFD housing and having a seal that engages a first raised edge on the VFD housing; and
an access cover coupled to the main cover comprising:
a seal that engages a second raised edge on the main cover; and light pipes aligned with the lights.
