I think the problem is that the 3 phase current graph is not smooth. As seen in the image below, there is no waveform as it should be in the 3-phase system, there are increases and decreases. At least the orange and blue phases should be around 24 amps, like the green phase level. I think there are fluctuations in the force graph due to these increases and decreases. Phase A=300*sin(2*pi*60*time), Phase B=300*sin(2*pi*60*time +120deg), Phase C= 300*sin(2*pi*60*time +240deg ). I also tried this like 300*sin(2*pi*60*time + 4*pi/3) phase shift.
As seen in the image below, it remains stable after some time.
As seen, when the current becomes stable, the force graph also begins to stabilize.
How can I make this more stable? Or how can I make it stable faster? I really can’t figure out where the problem is. I think the problem is in the wave function of the Voltage, but I’m pretty sure the wave function is correct. I really don’t understand what causes the wave function to be so unstable in the first place.
