Abstract

An axial field rotary energy device can include a rotor comprising an axis of rotation and a magnet. In addition, a stator can be coaxial with the rotor. The stator can include a plurality of stator segments that are coupled together about the axis. Each stator segment can include a printed circuit board (PCB) having a PCB layer comprising a coil. Each stator segment also can include only one electrical phase. The stator itself can include one or more electrical phases.

Claims (26)

1. A system, comprising:

an axial field rotary energy device having an axis, a printed circuit board (PCB) stator 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 VFD components coupled to the axial field rotary energy device;

an enclosure containing 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; and

a cooling system integrated within the enclosure and configured to cool the axial field rotary energy device and the VFD.

2. The system of claim 1 , wherein the enclosure comprises an axial length, a radial width relative to the axis that is greater than the axial length, and the enclosure is polygonal in shape when viewed axially.

3. The system of claim 1 , wherein, relative to the axis, the VFD components are mounted around and substantially co-planar with the axial field rotary energy device.

4. The system of claim 1 , wherein the VFD comprises a communications circuit configured to communicate with an external device.

5. The system of claim 4 , wherein the communications circuit is wireless.

6. The system of claim 5 , wherein the communication circuits is configured to communicate a status of the system to the external device.

7. A system, comprising:

an axial field rotary energy device having an axis, a printed circuit board (PCB) stator 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 VFD components coupled to the axial field rotary energy device and, relative to the axis, the VFD components are mounted around and substantially co-planar with the axial field rotary energy device;

an enclosure containing 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; and

a cooling system integrated within the enclosure and configured to cool the axial field rotary energy device and the VFD.

8. The system of claim 7 , wherein the enclosure comprises an axial length, a radial width relative to the axis that is greater than the axial length, and the enclosure is polygonal in shape when viewed axially.

9. The system of claim 7 , wherein the VFD comprises a communications circuit configured to communicate with an external device.

10. The system of claim 9 , wherein the communications circuit is wireless.

11. The system of claim 10 , wherein the communication circuits is configured to communicate a status of the system to the external device.

12. A system, comprising:

an axial field rotary energy device having an axis, a printed circuit board (PCB) stator 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 VFD components coupled to the axial field rotary energy device, the VFD comprises a communications circuit configured to communicate with an external device, the communications circuit is wireless and is configured to communicate a status of the system to the external device;

an enclosure containing 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; and

a cooling system integrated within the enclosure and configured to cool the axial field rotary energy device and the VFD.

13. The system of claim 12 , wherein the enclosure comprises an axial length, a radial width relative to the axis that is greater than the axial length, and the enclosure is polygonal in shape when viewed axially.

14. The system of claim 12 , wherein, relative to the axis, the VFD components are mounted around and substantially co-planar with the axial field rotary energy device.
