FluxMotor® 2022.2 Release Highlights
Altair EmployeeTHERMAL TRANSIENT COMPUTATIONS FOR RELUCTANCE SYNCHRONOUS MACHINES
Because they are simple and cheap to manufacture, Reluctance Synchronous Machines have great interest for many applications. It has been introduced in FluxMotor and this new version is adding capabilities to characterize its performance. A new test has been added to evaluate the impact of electromagnetic performance on thermal behavior of the machine in transient mode. The thermal working point defined by the speed and a set of losses can be considered to compute the temperature charts and the main thermal parameters, like the heat capacities and the thermal time constants.

A FAST AND PRECISE METHOD TO COMPUTE AC LOSSES IN WINDINGS
AC losses in the windings of high-speed machines is something to be considered as it limits their efficiencies. Evaluating them using pure finite element method is usually cumbersome, because you need to represent each wire and a lot of computation time may be required. A semi-analytical approach has been developed in FluxMotor to evaluate quite precisely these losses in a reduced amount of time. It can be applied to both circular or rectangular wires. You can then efficiently get precise evaluations of the losses in your machine.

HOW ABOUT GENERATING A 3D MODEL IN A FEW CLICKS ?
From FluxMotor, you can now decide to generate a 3D model that can be directly used in Flux. The model is fully parameterized and has all the geometry, the coils, the mesh and the physics defined to solve in magnetostatics. The user can decide about the length of the machine, and also about the use or not of symmetries and periodicities. A great gain of time to create 3D models ! You can do this for permanent magnet machines or reluctance synchronous machines with inner rotors.

AN EASY-TO-USE EXPORT OF LOOK-UP TABLES FOR SYSTEM SIMULATION
Look-up tables can be generated and easily used in Activate and Altair’s new tool for Power Electronics PSIM. Associating the modeling of the machine, the power converter and the control enables to get a better evaluation of the motor drive efficiency as a whole.

WHAT IF YOU COULD AUTOMATE THE USAGE OF FLUXMOTOR ?
Automate tasks or connect various tools together in a global automated workflow are great to speed-up everyday’s design work. This is not so well-known, but FluxMotor does have some scripting capabilities included, based on Python. In this version, a scripting tool and also the possibility to record scripts from Motor Factory are provided in standard mode, which makes it easy to automate FluxMotor usage.

AND ALSO:
- Induction machine characterization enhancement through SSFR test, and use of a “frozen permeability” approach for more accuracy.
- Improved Material application with easier navigation and additional material data export capabilities.
