Capacitors for a 24v wheelchair motor servo

Other Hardware General Electronics
1

Hey,

I'm in the process of building a 24v wheelchair motor servo, and my knowledge of electronics is quite small but I try and learn what I can.

I used a bts7960 motor driver because I have used them in the past with past wheelchair motor projects and they did well. However this time I smoked one of the chips on the driver.

I had connected the internals of a small servo to the wheelchair motor to get position, then to the motor driver, and was controlling it with a potentiometer. It worked for a little bit however the jolts and vibration from the motor was very excessive. Then....the motor driver started to smoke, so I pulled the plug on my power supply.

I have read that using capacitors can help smooth out the voltage or current going to my load. I will be using around a 100nF capacitor to smooth out the potentiometer, but what size should I need for the wheelchair motor and where is the best placement for them? I am thinking I will need multiple 1000uF?

Any help or other suggestions is greatly appreciated, thanks!

Don't all reply at once!

This very much sounds like you connected it incorrectly this time.
Of course we will need to see a schematic of how it is wired.
A capacitor will not help.
