You need to test at least two different load situations to the LPF. Not talking about the regulator or driver. Back to the filter 😁 1.all servos is stall condition 2. All servos in idle. Right?

all servos in stall condition can draw more then 30A and this is not what i'm going to make :-)

wait a bit for the circuit i'm going to make

But more problematic I see the second condition in idle

I made a random filter here but in reality i'm going to use a 30uH inductor with 4400uF capacitor bank

Be aware this combination is probably the most critical for atmel default pwm frequency. Check it in simulation first
