1. WOW thanks a lot!!! That explains everything. I needed to sum the 3 graphs of power, it makes sense now. I still can't believe I have 97% efficiency with this thing lol I'll double check it. Have a good day.
2. Just to be sure, this is how I'm doing the power balance right now (the numbers are rounded): Torqueelectromag(mechanicalset rotor) = 27Nm average Mechanical_power= 27Nm*1500*2*PI()/60 =4200W ** PowerP(current source) over a period = 2100W rms value * 3 current sources =6300W = P_input Then I calculate the joule losses on the stranded coil conductors with a sensor. It gives a triphasic sine wave that goes from 0 to 9W . The sum of the 3 waves is about 13W constant. The same but for the resistors that I put into the circuit: sine wave with 30W peak. the sum of 3 waves is 45W constant. Bertotti losses = 2,56W Since you mention I need to multiply by four, the end result should be like: P_input = 4200W + 13W*4 + 45W*4 + 2,56W *4 = 4442 W P_input from current sources = 6300W diference = 1800W **Considering mechanical losses=0. Also, the motor is running at 1500rpm.
3. Thanks for answering, I've simulated a quarter and applied the periodicity to obtain the full motor. My actual bertotti losses are 2,58W * 4 quarters = 10W and I think it's too low. I'm not sure what I'm calculating incorrectly. I think I'm also mixing things up because I'm not sure when I need to multiply by 4 and when I don't need to. https://send.firefox.com/download/25f117c80a3e1ff3/#UjuguY_jRnr6PvaRreOgfg This is the link of my solved flu project. I did it on FLux 2018. On the advanced menu you can see the power balance macro, it came integrated on the software.

5. Also, I have a question regarding the Bertotti losses. It computes the average iron losses over a period but.. does it take into account the length of the motor or it just computes the loses on one slice of steel? Basically what I'm asking is, do I need to multiply the average losses * length of motor / thickness of steel slice to obtain the iron losses of the full motor?
