We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
