Congratulations for your knowledge and effort to pass it to others. You have a very clear way to speak. And the use of diagrams and animations make it easier to understand. God bless you always
Duane not sure if it’s because I’m out of the US, but URLs don’t work for. Thank u for your commitment to teaching and sharing knowledge. It’s priceless for those who want to learn and build knowledge to also share👌
Something you said in the first video reminded me of something Duane. You mentioned electricity on the "atomic level" which made me think of one of my friends that worked for Caterpillar for many years. He specialized in large Gen Sets and made the statement that a four inch cable actually required more diesel fuel and more power at the crankshaft to push the current up hill. He then explained that the electrons were actually travelling through the copper itself. - The statement always seemed to help me grasp the fact that something really was physically moving through the cable similar to a pump pushing water. Love the videos. Keep'em Rolling!
I'll have to read more about this. I assumed those are flyback caps, to flatten out the voltage surge when power is cut to the inductor, to protect upstream electronics from a reverse EMF voltage spike. It didn't even occur to me they would stop the motor more quickly.
Knowledge is more valuable than anything! Surprisingly, I subscribed to the electrical engineer's channel because I needed help with my math a while ago. It's always very interesting to see you talk about diagrams in depth👏👏😲😲
I can not see how the capacitor could release a counter EMF and thus braking the wiper motor. The capacitors's polarity is the same as the original power supply so its electrical field is not an opposed one. I like your videos. 8-)
First off I love all you’re stuff. But, when you talk about the shorts in this lesson don’t you mean that the is less resistance? If the resistance was high the fuse would not blow unless the wire was so corroded the normal wire in the electrical circle changes wire diameter bedside the corrosion is the new section of wire which could create heat and burn open that section of wire if the amperage to push pass that section of wire is now below the amperage rating of the fuse an open would result. Loss or less resistance is the cause of shorts. Thank you for the great video.
Those capacitors have NOTHING to do with "dynamic braking". They are for filtering high frequency electrical noise created by the motor brushes. They are properly called "bypass capacitors", because they bypass or shunt the high frequency signals directly to ground (the motor housing). Capacitors will pass AC current, but not DC current. If dynamic braking is used, it is accomplished inside the intermittent control unit, probably by shorting the motor lead to ground or shunting it with a resistor. The capacitors are needed to keep the brush noise from interfering with the electronics in the control module.
I think his explaination is essentially correct if it were an AC motor. Much like a start capacitor on a starting winding helps to add torque and power on an AC motor. I I agree with u that those are more for bypass caps and don't know why he didnt even mention the resistors in the circuit. He may have in part 1 I did not see it. But I think it is what it looks like the braking simply comes from losing contact on part of the gear but momentum carries it on through and is timed to correspond when the motor is not pulling the weight of the wipers. If the motor kept pulling that would cause a surge and make it "jump"when it re-engaged with the load of the wipers. The resistors are what is slowing the motor hence slowing the wipers. But I may be wrong. Electronics is a hard concept for people to grasp sometimes and I think we all kind of reach our own understanding of how certain things work. When u get into things like dynamic braking I find that some people have a slightly less than exact understanding of the details so thet can grasp it. Still another great video from a very knowledgeable gentleman who is kind and generous enough to take time to teach others. I think he is an excellent teacher and I have learned alot in his videos. It was still educational
Mr. Duane: Of Course I Liked This Videos (1 and 2). A question: Does this Dynamic Braking wiper motor system is a Porsche item? Watching Mr. McIntire video it is deductible that the same wiper motor can be used as a Dynamic Brake instead of using Capacitors, by simply closing a circuit on It. Please Enlighten/Correct me. Thank You.

Who wouldn’t like these videos. Ofcourse we want more!

That was a good way of describing it, and accurate. Sometimes us old guys know how to describe things the way we've found them to help

YES... More videos like this please. Thanks for all the effort you put into your videos

Good ❤
Yes, of course. We want more videos like these.

I like all the videos you have made. thank you for educating us.
A link to the video in the description would be a good idea.
done to watch my requested video!hope you make more videos like this. Thank you
Great video but will have to watch it a few times.
Nice !
Thank you. Great Video . Thumbs up. Richard's Auto and Air.
Interesting! Thanks for sharing 👍

Great vid but your tic tock bell is so annoying, get rid of it
Copy and paste? Put the link in description for crying out loud!
Respect please!
