interior permanent magnet synchronous machine ONELAB
Hello everyone, I am currently developing a project for a machine with a magnet inside the rotor, I have a simulation already made, as can be seen in the figure, I have some questions and if possible I would greatly appreciate your help:
Can ONE LAB work with magnets inside the rotor without having to alter the pmsm_8p_circuit.pro file or the machine_magstadyn_a.pro file, of course I had to modify the machine_magstadyn_a.pro file, to define the new regions, but just change in that?
Do you know how BACK calculates or estimates emf?
Does performing the simulation give a completely wrong waveform for the torque as shown in the figure?
applying current to the stator returns a negative torque, how is that possible? , it is very likely that my simulation still has problems,
when the simulation is carried out without considering the current, the values to return for torque are the values corresponding to cogging torque ??? And one last question, what is the difference between the torque that returns from the rotor and from the stator.
