The computation of the current density in magnets and magnet Joule losses can be wrong
For SMPM machines, when the different magnets are in contact, the current density and the Joule losses computation can be wrong. This is because magnets are solid conductors of the type: “No circuit – open circuit conductor”. This circuit coupling type doesn’t work correctly when solid conductors are in contact. This issue occurs regarding the test computations in FluxMotor as well as while exporting files to Flux. (ref.: SLVFXM-10916 + SLVFX-40259).
Working point – Square wave – Forced I – Average computation of quantities
The computation of average quantities like iron losses, the Joule losses in magnets, and torque is not executed over a full electrical period. That can lead to wrong results (ref.: SLVFXM-14091).
Maximum speed computation
The estimation of the maximum speed is wrong for the tests “Working point - Sine wave – Motor - U-I” and “Working point - Sine wave – Motor - T-N” when the control mode MTPA is selected (ref.: SLVFXM-10916). The computation is always performed by considering the MTPV command mode.
