The construction of the motor determines the amount of noise it will make and at what frequency it will make the most noise. The noise is caused by the vibrations of any loose windings plus the vibration of the armature, especially if it has low mass, as in small inexpensive motors. 2 KHz or higher is usually the best frequency for quieting the vibrations.does the motor used determine at what frequency it should run ? I would not be running the motor very slowly as the application for the motor is to run circular saw.
I have not done any calculations to find out what frequency your circuit is running at or what frequency it will be with a 0.01uF capacitor. I suggest that you try it and see what happens. It will not cause any damage.Sorry about my silly questions, just a beginner with electronics. Learning as I do things.
So I was thinking a cap as low as 0.01uf, would that be ok ? The motor used here is a 775 dc motor. Runs on 12v at 5.7A max
