Abstract

A modular stator adapted to be used in a transverse flux electrical machine (TFEM) includes a plurality of phase modules comprising respective halves sized and designed to receive therein a plurality of cores about a rotational axis. The phase modules are adapted to be assembled together to produce a multi-phase stator and disassembled to replace or maintain a phase module. The phase modules are configured to be angularly shifted from one another to produce a multi-phase TFEM. A TFEM phase assembly and a kit of phases components sized and designed to assemble a multi-phase stator are also encompassed by the present application.

Claims

1. A multi-phases rotatable transverse flux electrical machine (TFEM) comprising:

a stator portion including a plurality of phases modules, each phase module comprising an independent housing sized and designed to be operatively assembled together about a rotational axis and angularly shifted from one another to produce multi-phases current; and

a rotor portion comprising a number of phases corresponding to the number of phases of the stator portion, the rotor portion being adapted to be operatively assembled about the rotational axis.

2. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein the plurality of phase modules is substantially identical.

3. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein at least some of the phase modules include a mechanism for axially positioning two adjacent phase modules.

4. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein at least some of the phase modules further comprise a cooperating positioning mechanism adapted to angularly locate about the rotational axis adjacent phases axially assembled together.

5. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein the TFEM comprises a pair of support portions adapted to axially secure the phase modules together, wherein the support portions comprise a cooperating positioning mechanism adapted to angularly locate adjacent phases axially assembled together between the pair of support portions.

6. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein the TFEM is adapted to be assembled with a number of phase modules in factors of two, for producing a two-phase current, and adapted to be assembled with a number of phase modules in factors of three, for producing a three-phase current when the TFEM is rotatably actuated.

7. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein TFEM is adapted to be disassembled to replace a phase module contained therein.

8. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein the phase modules are configured to be assembled with different angular shift thereof.

9. The multi-phases rotatable transverse flux electrical machine (TFEM) of claim 1, wherein phase module housing including a wire opening thereof adapted to receive therein coil wires extending outside the phase module, the wire opening of each of the phase module being angularly offset from the wire opening of an adjacent phase module.
