Explanation of Lq, Ld and how it relates to motor inductance


I'm pretty much a novice to motor controls, but I was wondering if any of you could explain the concept of d-axis and q-axis inductance and how it relates to the inductance L that is usually specified in motor data sheets. Also, is the phase to phase inductance the same as the inductance at maximum current? Thank you!

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
