Alongside the software we ship, Orbitronix runs an applied research programme in electric propulsion hardware. The work is analytical first: derive the physics, check it against published data from other groups, then hand it to simulation and test. Every output is labelled for what it is, so a framework is never presented as a result.

Inner rotor thermal coupling as a design constraint in multistage axial flux permanent magnet machines with directly cooled stators

Stacking stages on one shaft raises torque without growing the diameter. Cooling the stator windings directly lets them carry more current. Put the two together and a part appears that neither line of research has studied: the inner rotor, which has no coolant path of its own and sits between two warm stators.

Where the work stands

A theoretical study cannot prove that a machine will perform. It can derive the physics, verify it against measurements made by others, and state exactly what only simulation and a prototype can settle. This is the ladder we are climbing, and where we are on it today.

L1Theory

Physics derived and checked for consistency, then the analytical model verified against published measurements from other groups, with errors reported.

Framework published
L2Preliminary spec

A preliminary machine specification derived from a defined propulsion requirement, with every assumption stated.

In progress
L3Simulation

Three dimensional electromagnetic and coupled thermal finite element analysis.

Planned
L4Prototype

A two stage machine built with rotor temperature telemetry.

Planned
L5Test

Model, simulation and measurement compared directly.

Planned
Lab
participation.

The next levels of this programme need facilities that belong in a university lab. We are looking for research groups in electric machines and thermal engineering who want to take part, whether that means sharing data, running simulations, hosting a prototype or supervising doctoral work.
