What are these and what do they do?

[D.P.]

If memory serves me correctly, those capacitors help provide a voltage boost to the motor, in order to help the motor quickly build up speed.

I believe washers have capacitors on their motors - just not dainty orange smarties.

Possibly, or they could just be noise removal.

I know that on Scalextric cars these have the added advantage of stopping them interfering with electrical equipment like TVs

I doubt it at those low frequencies, indeed Scalextric were DC.

I doubt it at those low frequencies, indeed Scalextric were DC.

Would the current being transfered through the brushes not lead to noise though; if spinning at say 3000rpm, that's 50Hz. Or do you mean to say that this 50Hz is too low to interfere with TVs?

Its my understanding that they kill of electrical noise from the motor brushes ect, so they A) dont cause the radio control to mess up/act iratically B) and b, stop electrical noise/distrubance/feedback damaging the control circuit / rc circuit in the car.

I think, in this application they are called "Smoothing Capacitors" but i might be wrong

correct


but they are not smoothing in this case the are to suppress the RFI ( radio Frequenct Interferance) to stop the care going crazy

 

[malfunkshun]

yup RFi suppression primarily. If you took them off you might have reduced workable range on your transmitter.

Erm, it's an R/C car dude

Cheers.

ooops i realy most not post while half alseep or drunk it all makes sense now
