Hi All,
I want to measure the back EMF of a 3 phase motor in star formation. Just by turning the motor shaft by hand i should be able to measure 3 voltages (one for each phase) and see their relationship. The problem is i am not sure how to connect the GND of my DAQ.
I want to use a differential measurment for each phase.
can anyone help.
thanks
