I just don't understand the reasoning behind using capacitors for limiting back EMF here:
https://www.electro-tech-online.com/threads/value-of-the-capacitor-parallel-with-the-dc-motor.21305/
and why the same reasoning wouldn't apply to a PWM situation, especially if the PWM signal is above the motor's rated voltage. Aren't you in effect, by using the high-voltage PWM signal, sending multiple "spikes" of a sort to the motor?
Or did your answer presume the caps mentioned for the the purpose in the other post, i.e. since there are (presumably) caps for back-EMF purposes, additional caps for PWM are redundant?
I'm just trying to understand the reasoning behind it, is all.
