Altair FluxMotor 2019.1.1 Release Notes - Date: 14 May 2020

Altair FluxMotor 2019.1.1 is available with corrections and improvements. It can be applied as an update to an existing installation of FluxMotor 2019.1.

Fixed issues of FluxMotor 2019.1.1

Induction machines with skewed topologies - Motor Factory – Test Environment
- Very often, the results of computations may be wrong when a skewed topology is considered for the squirrel cage or for the slot (ref.: FXM-12398).
The visible signs of this problem were mainly the following ones:
. Anomalies on the shape of the generated curves versus slip (or speed) like torque-slip curve
for instance
. The results got with the test "Working point / Sine Wave / U, f, N" are not consistent with
those got with the test "Performance mapping / Sine Wave/ T(Slip)"

Induction machines - Motor Factory – Design and Test Environment
- End-ring impedance computations using the user mode fails (ref.: FXM-12399).


- The rounding value for the slip is not well considered. For instance, a slip equal to 2.33333 % cannot be considered. The nearest possible value is 2.334 %. This leads to a crash when the tests are run. (ref.: FXM-12368).
- CS and OCS temperature are not considered for computing end-ring inter-bar resistance in the DESIGN environment. The temperature of bars is considered instead (ref.: FXM-12451).
- OCS temperature is not considered for computing end-ring inter-bar resistance in the TEST environment. The Connection Side temperature is considered for both sides (ref.: FXM-12452).
- The computation of the average value of the end ring inductance doesn’t consider the Opposite Connection Side component (ref.: FXM-12561).

Induction machines - Motor Factory – Export Environment
- The X-Factors of end ring resistance and inductance are not reported in the section ("Winding and cage") where test result values are displayed. To be noted that X-Factors are well considered in the computation (ref.: FXM-12550).
- The inductance X-Factor using for induction machine tests and exports is wrong. It is replaced by resistance X-Factor (ref.: FXM-12562).

This issue has been corrected


FluxMotor is a flexible open software tool dedicated to the pre-design of electric rotating machines. 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.
