TMS320F28027F: Instaspin-FOC with two phase-to-phase voltage sensors

Part Number: TMS320F28027F

Hello,

I would like to know if Instaspin-FOC will work with two phase-to-phase voltage sensors. (For example: Uab & Uac)

In the example codes, Clarke transformation is applied to three voltages: Ua Ub Uc. Since the common mode voltage is not used, I see no reason why it cannot work with Uab & Uac.

If it will indeed work, does the same requirements apply for the voltage sensing circuit? (Low pass filter design and parameters)

I am asking because I have multiple motors and would like to reduce the number of ADC channels used.

Thanks.
