Here, the maximum speed of the motor is 2000RPM. That make the first order at 2000/60 = 33Hz and the tenth order at 330Hz. In order to optimize the computation, we will then limit the FFT bandwidth to 5kHz, the overlap to 67% and the number of lines to 1601 to have a correct precision. | Here, the maximum speed of the motor is 2000RPM.
