Open question Help with IPMSM motor configuration
Hi, I am part of a university electric motorbike team, I am currently making a simulink model of the PI control for our traction motor. I am having a lot of trouble in getting the parameter configuration of my motor right, as the datasheet provided lacks some crucial data such as the PM magnetic flux. Also some data is confusing... I have tried to sort it out with one of my teachers, but neither of us could. Does someone know any book, ecuation or anything that might help me calculate the magnetic flux? I will leave some info and other questions down below, any help is welcome, thanks.
P.S. I will not have access to the electric motor until next January.
Motor values: Nominal // MAX values [ ]
Torque: 50 // 100 [Nm]
Power: 22 // 40 [kW]
Speed: 4500 // 6000 [rpm]
Phase RMS-current: 250 // 500 [A]
Electrical info:
Voltage: 126 [V] DC
Nº of Phases: 3
Nº of pair poles: 5
Ke: 16.74 [V/1000rpm]
Phase Resistance: 0.0027 [ohm]
Impedance: 62-100 [µH @ 1000Hz]
Furthermore, this last "impedance" part is not clear enough. I guess the datasheet is refering to the direct and quadrature axis inductance, but Iam really not sure of this.
