hello im a newer. im know that the motor parameter is very very important in this FOC.we need it to estimate angle roto flux. im used to use it in my project with TI chip (f28069 ) but i have so many experiment to find some parameter (when i at experiment lab in school ) . about Tr = Lr/Rr = Rotor time constant. and if we need sensorless we need more parameter to estimate speed. but now my motor dont have them.its just have volt/apm/speed... .and i cant do experiment because i dont have enough equipment like when i at school. So. if u have a solution about this. pls help me. we will disccuss about this. thank u. and sorry for the Bad english skill lollll
