A liquid-cooled rotating electric machine may include an inner stator and outer rotor configured to rotate about the stator. A hub may be disposed within the inner stator and a heat exchanger may be disposed in the hub. The heat exchanger may be configured to enable the flow a liquid through it to dissipate heat from the stator.

An axial field rotary energy device or system includes an axis, a PCB stator and rotors having respective permanent magnets. The rotors rotate about the axis relative to the PCB stator. A variable frequency drive (VFD) having VFD components are coupled to the axial field rotary energy device. An enclosure contains the axial field rotary energy device and the VFD, such that the axial field rotary device and the VFD are integrated together within the enclosure. In addition, a cooling system is integrated with the enclosure to cool the axial field rotary energy device and the VFD.
