1. A system, comprising:
axial field rotary energy devices each having an axis, a sealed enclosure, a printed circuit board (PCB) stator, a sensor and rotors having respective permanent magnets (PM), and the rotors are configured to rotate about the axis relative to the PCB stator;
a variable frequency drive (VFD) comprising one or more of:
a rectifier module,
DC bus,
a communication (I/O) module, or
line inductors connected to the output of the inverter module; and
the inverter module,
a control module,
contactors coupled between the VFD and each of the axial field rotary energy devices and each contactor is configured to be independently controlled by the control module;
wherein
the VFD is electrically coupled to the axial field rotary energy devices, and the VFD separate from the sealed enclosures of the axial field rotary energy devices; and
the control module is configured to receive signals from the sensor located in each of the axial field rotary energy devices and relay a command to a respective contactor to disconnect a respective axial field rotary energy device, if the parameter monitored by the sensor exceeds a set threshold.
