Measure current sensor 2 vs 3

Dear TI,

You can choose the NUM_CURRENT_SENSORS: 2 or 3 sensors

My question is what will be the preformance difference between 2 current measurement vs 3.

Best regards

this is discussed in Chapter 17 of SPRUHJ1

You need 3 sensors if using shunts and want to operate beyond the sinewave modulation region (to create more voltage to each phase and hence more speed or torque).
