Modular axial field rotary energy device with PCB stator and variable frequency drive system

A system, comprising:

• an axial field rotary energy device having:
• an axis of rotation;
• a rotor coaxial with the axis and having a shaft, bearings, bearing caps, rotor disks, 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;
• an enclosure having two enclosure sections with at least one of the enclosure sections having an inspection port oriented radially, relative to the axis, and aligned with the PCB stator and the air gaps, such that the inspection port provides a direct line of sight to the air gaps;
• an annular shim located between a respective bearing and a respective bearing cap, wherein an axial position of the rotor is configured to be adjusted and widths of the air gaps are changed by adding or removing the annular shim;
• and the system further comprises:
• a variable frequency drive (VFD) assembly coupled to the axial field rotary energy device.
