Abstract

A housingless transverse flux electrical machine (TFEM) includes a pair of halves adapted to receive therein a plurality of cores and a coil therein. The halves are the exterior boundary for the environment and the TFEM can be in operating configuration without further housing.

Claims

1. A housingless transverse flux electrical machine (TFEM) comprising:

a stator including at least one phase module comprising

a pair of opposed halve members respectively including a plurality of core-receiving spaces sized and designed to receive, locate and secure therebetween a plurality of cores; and

a coil operatively disposed in respect with the cores inside each phase modules, the pair of opposed halves being the exterior housing of the stator allowing the TFEM to be used without further housing.

2. The housingless transverse flux electrical machine (TFEM) of claim 1, wherein the phase module is axially binded with support portions compressing the at least one phase module.

3. The housingless transverse flux electrical machine (TFEM) of claim 2, wherein the support portions are bound together with a plurality of securing members.

4. The housingless transverse flux electrical machine (TFEM) of claim 3, wherein the plurality of securing members are disposed on the outside of the at least one phase module.

5. The housingless transverse flux electrical machine (TFEM) of claim 2, wherein the support portions support the at least one phase module and is adapted to operatively secure the TFEM to a support structure.

6. The housingless transverse flux electrical machine (TFEM) of claim 2, wherein the support portions, when axially seen, are visually covering the entire at least one phase module.

7. The housingless transverse flux electrical machine (TFEM) of claim 1, wherein at least some of the halves members are visible when the TFEM is in operation.

8. The housingless transverse flux electrical machine (TFEM) of claim 1, wherein halves comprise radial plans perpendicular to the rotational axis of the TFEM.

9. The housingless transverse flux electrical machine (TFEM) of claim 1, wherein a distal radial surface of the phase module is waterproof.

10. The housingless transverse flux electrical machine (TFEM) of claim 1, wherein a distal radial surface of the phase module is cylindrical and parallel with the rotational axis of the TFEM.

11. The housingless transverse flux electrical machine (TFEM) of claim 10, wherein the phase module further comprise resin therein for securing the coil and the plurality of cores in the halves.

12. A housingless stator adapted to be used in a rotatable transverse flux electrical machine (TFEM), the housingless stator comprising:

at least one phase module comprising

a pair of opposed halve members respectively including a plurality of core-receiving spaces sized and designed to receive, locate and secure therebetween a plurality of cores; and

a coil operatively disposed in respect with the cores inside each phase modules, the pair of opposed halves being the exterior housing of the stator allowing the TFEM to be used without further housing.

13. The housingless stator of claim 12, wherein the phase module is axially bound with support portions compressing the at least one phase module.

14. The housingless stator of claim 13, wherein the support portions are bound together with a plurality of securing members.

15. The housingless stator of claim 14, wherein the plurality of securing members are disposed on the outside of the at least one phase module.

16. The housingless stator of claim 14, wherein the support portions support the at least one phase module and is adapted to operatively secure the TFEM to a support structure.

17. The housingless stator of claim 14, wherein the support portions, when axially seen, are visually covering the entire at least one phase module.

18. The housingless stator of claim 12, wherein at least some of the halve members are visible when the TFEM is in operation.

19. The housingless stator of claim 12, wherein halves comprise radial plans perpendicular to the rotational axis of the TFEM.

20. The housingless stator of claim 12, wherein a distal radial surface of the phase module is cylindrical and parallel with the rotational axis of the TFEM.
