MCF8329EVM: Setting the BASE_CURRENT in delta-connected motor and wye-connected motor

Tool/software:

Hi TI Expert

We are developing an electric water pump using a 48V BLDC motor (R = 0.019 ohm; L = 0.1 mH), delta-connected motor.

About the calculation of base current in the datasheet, it will be

BASE CURRENT = {1.5/(RSHUNT*CSA_GAIN)}

GD_CONFIG2 = BASE CURRENT * 32768 / 1200

When considering a wire-connected motor and a delta-connected motor with the same R for each phase resistor, the total current flowing in the motor will be three times greater when the same voltage is applied.

From this image I thinks above calculation of Base current is use for wye-connected motor.

So is the calculation change when I use delta-connected motor with the same R phase?

Thanks,
