Using Ld and Lq inductance values for IPMSM

Hello!

I want to implement FOC for IPMSM. I am using the 'Permanent Magnet Synchronous Machine' model in Simulink.

It asks for armature inductance value, but I only have Ld and Lq values. Can I just put [Ld Lq] in that field?

Additionally, you may also use the Ld Lq and fluxPM values using the blocks MTPA Control Reference and LUT based PMSM Control Reference blocks too.

Additionally you can refer to the following pages for how to use both the blocks

Assuming that you want to implement FOC using ipmsm. You can use Ld and Lq I understand that you want to implement IPMSM using FOC.
