About excitation current

After commissioning the motor in several days .I wonder whether the odrive have field excitation current ,if it is yes,how does it couple with control current?.
THANKS

Are you trying to control an induction motor?

Actully I don’t really know what is induction motor. Maybe the stator generates a rotating magnetic field to drive the rotor in theory? And the brushless motors based on this principle? Otherwise, I have no idea to the SVPWM control so I suppose it integrates the excitation circuit into the algorithm. Is that correct?
