How Motors Work For Beginners (Episode 1): The DC Motor: 032

I explain how the DC motor works in a simply and patient way. I use several experiments that you can copy at home. Then I show a Treadmill DC motor cut open and working so we can see the moving parts!

He was fascinated with magnets at a very early age and this was my opening to teaching him to this point.

Your videos are wonderful and have been a great help. This week we will build a simple dc motor and carry on from there. I’ve always wanted an excuse to make one and now I have it.

I just use what I learned from a 5th grade science class, and experimented with circuits. Of course I watch videos too to avoid hurting myself. The way I learn is kind of dangerous, but so far I haven’t hurt myself. I would recommend buying a kit though if your kids have no experience with building robots. It’s a safe method of learning if your dealing with children.

Jeremy, I'm an EE senior and I've been confused about how that works for years. In class we immediately go to Maxwell's equations or some equation where we have to calculate the turns, current, or something along those lines but I've never got to see how a real, usable motor works. At the end when you had the magnet under the rotor and you switched polarity, I started talking to you through the computer screen saying, "take away the magnet, take away the magnet". I needed to see for myself that the current could still be present but there had to be a magnet for it to rotate.

Hi Jeremy! Great video, extremely helpful. Inspired by you, I've started picking up things with motors when I see them along the side of the road, taking them apart, and playing around with them. One of the common problems I have is the brushes producing sparks along the commutator. I'm guessing it's because they're not making a firm enough contact and it's causing the electricity to jump the gap. Is there an easy fix for this? Perhaps that's why people are getting rid of these things in the first place... They smell like electricity when ran! I'll be watching with interest, thank you for all the great videos!

[@ferky123]

flashpointwhite there is. It's called replacing the brushes.

[@JeremyFieldingSr]

If you can find replacement brushes, that would be the first thing... It sounds like they are too short and are starting to arc.

[@aaronmezger]

Brush motors always make at least a faint arc when running properly. It's from the electricity transfer. When you have an abnormally large arc, it's from either the brushes being too short and causing a larger air gap to need to be traversed, a short in the motor (typically the armature/ rotor but the stator field is possible as well), or an extreme amp draw due to heat generated from overloading (bearing seizure or overtasking are common culprits) or low voltage. Ohm's Law explains the relationship between amperage, voltage, resistance, and heat and how if you change one value it affects the others.

It's because of people like you that I can rebuild starters, and alternators,and have an understanding of most electrical components. Thank you so much.

Its midnight and I'm looking for kid friendly KZbin channels to explain to my inquisitive and mechanically inclined 4 year old how machines and motors work because this mama doesn't know much about that stuff. I'm 40 minutes and 5 videos deep into this channel and I've learned so much through your explanations. I honestly think my 4 year old will get a good grasp of what is going on if we conjoin some science experiments together with your videos. I look forward to showing him your videos and deconstructing/fixing/creating some stuff with him. THANK YOU!!!!!

I've been an electrician for 15 years and never fully understood the differences in some motors. what I want to know is if their is a motor that ran in reverse generates electricity. and fundamental differences in motors and generators

[@JeremyFieldingSr]

It will come as part of the series! Thanks for letting me know

[@MikesToolShed]

Jeremy Fielding awesome video can't wait for the rest. very good at explaining things

[@bluesky6327]

That's great to know!. I have several older tools that are belt-driven and use induction motors, and this has helped me start to understand the differences between these and DC motors. I'm looking forward to learning more!

[@ferky123]

If you run a motor with an outside power source like a turbine or a gasoline engine then it's a generator. If you use electricity to rotate the generator to do work then it's a motor.

Would it be correct to say that the same thing is occurring but in different directions? Isn't it just a movement of electrons?

I pressed subscribe when you turned on the current to the wire and the small magnets moved away like magic. Happy to have come upon this channel.

[@redgator78]

Thank you sir. We need good teachers like you. Eye opener.

[@johnroberts1505]

So.. this morning I decided to watch some videos on how electric motors worked. After watching more than a few I stumbled across this one. Without question this one is the best. Thank you for teaching this 70 year old something I wanted to know about all my life.

[@parkavenue6970]

I just starting to watching your videos but I wanted to pause to thank you and to tell you that I'm overwhelmed with gratitude towards you!!!

[@jacverrijt1743]

Gr888 job, only a few are given the gift to, explain, difficult to understand physics principles in easy to understand and follow tutorials. You are one of those who have that gift.

[@johnx9318]

You are a natural teacher mate. Thanks.

[@Patrick_Gray]

Thanks for the video. I started working at my dads automotive electrical shop back in 1961 when I was 12 years old. I read every thing I could find about electricity and motors. Never saw a demonstration as good as yours. Later in life I went to University of Delaware and also the USAF electronics school.

[@jamesgatten8575]

This is the best demonstrational video of a dc motor I have ever seen. You, sir, are very gifted as a teacher.

[@tesfahunmintesnot7807]

Man after took a College classes and training classes and watching KZbin videos nothing is better than this video thank you so much you the best 🙏🏽

[@newtontaylor7976]

Thank you for making this series! I am 50 and moving from a water-based fire protection career to an industrial electrical maintenance career. Having to learn this info in the challenging times that we are in is difficult for an old school guy like me. You have a God given ability to teach and i am thankful to have found your channel. Keep the videos coming and I will be watching to continue learning. Thank you and God bless!

[@andycumberbatch4140]

This guy has such a thorough and simplistic way of teaching; not to mention intristing that even such a challenging subject, just feels comfortable even to a complete novice. He reminds me a lot of John Smiley. They simply don't overwhelmed you with a whole lot of technical terms and jargon to show off their knowledge, but simply focuses on the students. Great job brother, keep up the good work.

[@99Randizzle]

Absolutely brilliant!! Echoing others, I'm 64 and was always a bit fuzzy on motors, AC and DC. Jeremy, you have a precious gift, one that is rare to be able to unpack the concepts involved in motors and generators and in plain language along with your simple demonstrations/teaching aids, explain them. A big thank you. Please carry on demystifying the world for us less gifted but curious ones.
