right, motor is a low pass filter.
However, harmonic current will cause additonal loss, motor will
be very hot. So it is always required that feeding motor with
pure sinusoidal current.
anq, I suggest you either change the inverter to be a SPWM inverter,
or using a LC filter to filter the high order harmonic.
The first technique is more advanced. You need a high frequency sawtooth
carier wave to perform the PWM. Then the output voltage of the inverter
will contain no low order harmonic, you just
