You could have used 3 pcs 120 degree phase shift OP-amps, connected in a loop. A to B, B to C, C to A. These would create 3 sinus waves. Then you connect the three inputs of the voltage-to-current amplifiers at the corners of the loop.

Your diagram does not address the misconception at all; it merely repeats the assertion in a graphical manner.

@matanpazi3777 3 ай бұрын

Would you care to elaborate? Misconception: Field weakening works by essentially lowering the motor's torque constant / back EMF constant. My claim: No, it does not. it's easiest to see that in 5:36, by adding current in the d axis, we can lower the voltage amplitude yet leave the torque constant.

There is also the issue of axis decoupling. The problem is that the d and q axis do not operate independent of each other. There are terms in each of the dq axis ODEs that cross corelate. This means that the d control loop will effect the q control loop and vice versa. One must use feedforward control to decouple these terms so that each control loop can act independent of each other.

It would be interesting to see how to control a doubly fed AC motor for position and variable speed. I understand it is related to controlling phase and frequency of one or both feeds.

@LamantinoElettronico 5 ай бұрын

Probably it would be very similar to controlling a pmsm, because if the machine is doubly fed it means there is a constant rotor field and so it is synchronous

It's like I see a summary of my senior year project back in the university 3 years ago. Back then we don't have clear explanation of this control method we only have to read though IEEE and textbooks to understand these things.

WOW, You need a VESC from Bennjamin Vedder, a controller that is open source. Man I would love to pick your brain to help me program my motor, can you explain how to calculate motor inductance difference iq-id? how do I calculate motor flux linkage? These are my measured motor parameters, R = 66 milliohm, Inductance = 366 microhenry with a max voltage of 84 volts, FOC, no field weakening yet.

@matanpazi3777 6 ай бұрын

Aloha, well there are several methods. First of all what do you need those parameters for? Does the motor even have saliency (Lq, Ld ratio)? You can identify them using step/sine injections and process the response for example. Or w/ an LCR meter, make sure to rotate the rotor to get min (Ld) and max (Lq) values. Regarding flux linkage, you can pretty much measure the bemf between phases and w/ some scaling get the value.
