I am designing an AGV for which I am in the process of selecting a controller IC for BLDC motor. I read through design considerations document by TI and came to know that FIELD ORIENTED CONTROL will be apt as the AGV will require to output higher torque. FOC is a new concept to me. From TI's document I was able to comprehend that the stator and rotor magnetic field should be orthogonal to each other. How can this be implemented?
