Altair FluxMotor 2019.0.1 Release Notes - 11 July 2019

Resolved Issues of FluxMotor 2019.0.1

Motor Factory–Design and Test environments
- The computation of the rotor initial position may be wrong under certain circumstances (ref.: FXM-11686).The value of the phase which is selected for sliding the MMF signal (spatial representation) affects the computation of the initial position of the rotor (POS_INIT) considered in tests. When this value is different from 0 degrees, this leads to wrong results.
- The computation of the end winding inductance is wrong when end winding topologies (Connection Side and Opposite Connection Side) are not symmetric. It is always computed as two times the value of Connection Side end winding inductance. (ref.: FXM-11649)
- Motor Factory –Export Environment –Export to Flux2D or Flux Skew. When exporting a model of induction machine with squirrel cage to Flux 2D or Flux Skew environment (Transient application, imposed speed), the controlled solving is carried out with the rotor position parameter instead of the time parameter. This leads to wrong simulation results (ref.: FXM-11825).
- Synchronous Machines with Permanent Magnets –When reloading a project solved with an efficiency map with a duty cycle the computation of a new duty cycle doesn’t work correctly. (ref.: FXM-11578 and FXM-11663)
- In Motor Catalog, “Edit”a motor from the comparator to visualize it in Motor Factory is not possible when it comes from referent catalog provided with FluxMotor (Re.: FXM-11673).

Additional warnings and bug list

Motor Factory –Export –Advanced tools –Flux 2D –Flux Skew
- The computation of the phase resistance of induction machines when exporting a model to Flux or Flux Skew is wrong. The considered reference temperature is the one defined in "Motor Factory / Design Environment / Winding X-Factors" instead of the one definedin the material database(ref.: FXM-11873).Note that the phase resistance computation is right for Synchronous machines. In that case, the reference temperature considered is the one defined in material database.

FluxMotor is part of Altair’s HyperWorks CAE Suite, which includes Flux the leading software for low frequency electromagnetic and thermal simulations. The software tool allows users to design and create machines from standard or customized parts, as well as to intuitively add windings and materials to run a selection of tests and compare machine capacity. Based on modern technology, the standalone platform offers fast and accurate computations. When necessary, connection with Altair Flux finite element software enables more advanced studies, taking into account more complex phenomenon.
