How To Size Electric Motors for Any Project: A Beginners Guide

[@Jeremy_Fielding]

I changed the plan! I will go live here on KZbin Sunday Oct 18 at 12pm Central Time! Join me and feel free to ask me anything. I look forward to meeting you all then.

Im thinking of making a homemade clothes washer using a 5 gallon bucket, on youtube you can find these are all manual, i intend to add on a motor, the concept is simple, you make a hole in the buckets lid, and you put a clean new toilet plunger through the lid hole, you add water, clothes, and soap, clothes the lid and move the plunger up and down. Creating a washing effect. For this i need a motor that would be strong enough to move wet clothes continualy, preferably an up and down morion every 2 seconds, thats where things get tricky because i dont know of any motors that are string with low rpms, thats why came to you, if anyone knows motors, its you. I would rather let you take on this project, being that you got all the motors and the skills, plus an awesome channel with loads of followers, but if you decline, can you at least point me in the right directtion for what kind of motor i would be searching for. Thank you.

[@tonywilson4713]

Jeremy well done on a practical guide to basic motor selection. I have been doing Control Systems, Automation and Robotics for ~30years and that has involved a lot of motor control. I've seen a staggering amount of development in VSD technology in that time. I call them VSDs for the simple fact that every other term is simply irrelevant these days. Even basic variable frequency drives are no longer just VFDs as they can control the voltage, current, torque, accel & decel ramps, DC injection for both braking and pull out and that's all before you get onto all the other stuff they can do. I have even used some of the more advanced drives to completely control internally entire sections of production lines and that was 15 years ago. These days the internal safety functions of many drives have a higher rating than simply cutting the power to the VSD with a contactor. Really goo do you to mention the inertia issue. That is one thing that so many engineers get horribly wrong and at times ruin entire projects as happened to me a couple of years ago. The inertia issue involves a square law and someone misplaced a decimal point. It should have been a very simple thing to check the final drive speed and THEY DIDN'T. The basic gear ration was out by a factor of 10 and that put the inertia ratio out by a factor of 100. By the time I tried to explain to people what had happened they were all running of cover and I got my contract cut (effectively sacked) as the messenger. If you want to do something let me know. There are so many BAD videos on motors and motor control. I really am scared that people will get hurt if they already haven't been. Some of these small 3D systems are seriously fast and its so easy to do this stuff that many many people take it for granted. Stuff people buy off the internet is not like going to Haas and getting a basic CNC mill. Haas, Fanuc, Hermle and others have to follow standards the small 3D printing, laser, cnc & waterjet crowd DON'T. FYI - I have been TUV FSEng certified in the past so I know the safety stuff very well.

[@stvooplayhouse]

I'd like to listen and learn.

[@naronaroyan323]

Any way you can tell me what kinda motor to buy or how much torque I need to turn a garden valve? I want it to apply to any valve, so it needs to be powerfull enough for any but not more then that...

[@enlightendbel]

One more thing you need to select on is if your motor needs to hold torque when standing still. A lot of applications only need motion, but controls like your bench saw probably are best with a motor with 0rpm holding torque so that pressure on the bench itself doesn't shift the tables position (which could screw up precision cuts). Most of that type of automation applications have more need for motors that can keep position than the motors being fast or generally powerful.

The "subpoena my kids" comment was the catalyst for a proper chuckle, but the "motivation" caused me to truly lose it.😂

[@DrychronRed]

I LOVE how practical your thought processes are. They're exactly how one would think through this, and THAT is what we need to know to learn how to do it on our own. 10 out of 10!

[@Quintanaroo2117]

Myself being a science and mechanical geek, I appreciate a well explanation of such topics. You sir need to be a teacher, you have a gift.

[@jasoncy31]

Seriously, love this guy's quiet and thoughtful way of teaching. I learn a lot from him.

[@SluSharkND]

Sir, you do a great job explaining any subject. But you "subpoenaed" your kids and then provided motivation for them to increase the speed, well, that just made my day and gave me a laugh! Thanks for sharing and keep up the great work.

[@neiljt4746]

I've never known anyone explain this as well as you, I'm hooked! Thank you for this.

[@paulfasolo8552]

This video should be shown in every HS physics class, the simplicity of your explanation is terrific!

[@JoeTrojan88]

Love it! Was so excited to see another vid from you! You provide a really great balance of technical detail, entertainment, and commentary! Thanks Jeremy!

[@flojotube]

My pullout torque is ON POINT... 😂 I am obsessed with this channel & ur videos man... I hit the like 👍 before it even begins EVERY TIME because there’s never a bad video. I’ve learned so much and have collected SO MANY items thanks to you. I just figured I’d finally drop a comment. Your kids are so lucky bro.. You seem like one of the most genuine & kind people on earth.

[@280zone]

Jeremy, I love listening to your reasoning things out though with analytical mind. but "Motivating the kids" cracked me up, thanks for starting my day off with a smile and a lesson.

I'm 68yrs old, have a Physics degree from UCBerkeley and I find this video to be 'Excellent!' Well done! Keep on educating the world you have a gift.

[@lambretatuga]

I just love the way you explain everything,plain and simple,even for the ones with no knowledge at all about the subject.

[@sidogpmj]

Thank you much. I have so much trouble doing research on electric motors. You say this is simple knowledge. It is so beneficial to come across this simple knowledge.

[@betterequipment5692]

Hello, you have phenomenal communication skills. A lot of people are knowledgeable but can't communicate their knowledge. You are great at both. Thank you very much!

[@athiker7209]

Thanks for sharing. I have been retired for 10 years, and I used to work on CNC machines back in the early 80s. I was the repair technician, so when replacing motors and parts, I usually had the part numbers. Several times a month I had to call our company engineers on oddities that I came across. I was amazed and thankful for the help they gave me, to get our customers back in production. For some companies the name on the part is more important than production. Even after matching the numbers for requirements, don't install a General Electric motor in a Westinghouse plant. You'll get a call to remove that #$_&+ motor from my assembly line. Lol, I finally got the line boss to simmer down, if I would remove the GE lables from the motor.

[@professorfukyu744]

Your videos are seriously my study material for my projects. This particular video was desperately needed. Thank you!

[@richadamiranda8810]

You have a great teaching voice and a command of engineering it seems. Nice video.

[@heatherryan9820]

Wow, I didn't know that so much went into picking a motor for a project. I definitely learned a lot by watching this, and will have to watch it at least a couple more times to truly start to grasp it, but thanks for the information.

[@gregsettle9725]

So glad I found your video. This answered some basic questions I have before I start my latest project.

[@mavericktruck6648]

Company I worked for (deep south) had some real problems (to say the least). They sent me to one plant where they kept burning Belt elevators up, they made Fertilizer of some sort there. If I remember right the elevator had heaters (overload protection) for twice the Horsepower. They did have a speed control installed on the driven bottom pulley but it was set to something like 45 seconds (before it would disengage). This was one of many blaring problems I found that day. You sir seem to be a competent Engineer, even if you are not formally educated in this. I since moved out West, while not perfect, the level of competence out here is vastly better. It was a pleasure viewing this.

[@bigbluesquidtv]

This is brilliant, I am literally starting a business making a machine based on your KZbin training videos. It’s invaluable and opened up a whole new world to me.

[@Deecups510]

Thanks for these detailed motor videos, they are great! I am getting much more interested in motors and now I'm looking at every device I come across as a potential source for parts. This and the videos of people making hydro power plants out of old washing machines has me inspired to make again! Thanks! Plus I'm going through my grandpa's awesome collection of old amazing machining tools and I have a gold mine of projects to work on. Mechanical Engineering major here.

[@TediumGenius]

I knew what you presented here.. but I just have to say I enjoy watching you present it in the ways you have! Getting your kids involved for the work example? That's GREAT!! I think you touch on the surface of the main priorities and choices really well, going just far enough to allow a someone new to your subjects enough information to decide if the subject is too complicated for them, or if it excites them enough to follow your other links and information to gain a deeper and effective knowledge in order to either satisfy their own tinkering curiosity, or to complete their own projects. Your videos are always great to watch! Keep up the awesome work!!!!!

[@jeffhidalgo198]

Mr. Fielding, I find your videos so informative and inspiring. My son just got his master's in Mechanical. I couldn't be prouder. Keep up the great work! Peace

[@BrettLovell-kx9bx]

I have 2 degrees but find myself in a job where I repair things and use my hands. I absolutely love it and that is why I do it. I never knew I was so mechanically inclined until I decided that it did not matter if I broke something that most anything could be fixed. Also, if you try to repair something that’s already broken it’s a moot point. Lesson learned just jump in and do it. You will build experience extremely fast if you have common sense and if you have common sense you can figure out a lot of things that you have never done before. When it comes to electronics and electrical things I am not very confident and with the risk of getting hurt or hurting others I am less likely to be so free about “just jumping in”. I have read cover to cover a college electronics book and an electrical book. Yet, this subject still allures me unlike any other subject. I think I will have to have someone actually teach me and I learn hands on. I came across this video today (the first I have seen by Mr. Fielding) and I subscribed within the first few minutes of the video. I do not subscribe much to anyone but I knew this guy was special. Mr. Fielding I have never had anyone explain the subjects you explained in this video in such a way. Nor have I understood those subjects in such detail and understanding. Although I knew what torque was I could never wrap my head around it and grasp it so fully. You are a wonderful teacher. I will recommend to anyone who is learning or even thinks they already understand the topics you teach to watch your videos and support your channel. I am a millwright and I build and repair lots of really cool things. You have really shocked me on how well you made this one video how well you got the ideas across. Thank you from the bottom of my heart for making these videos. I can’t wait to add some new elements and skills to projects that my twin boys (7) and I are going to be starting soon. Now time to go watch more videos!! Brett and sons Gabriel and Beckham-Hoover AL

Hey Jeremy Absolutely great job of explaining the laws of physics in a good simple to understand way and using your children as part of the lesson, brilliant. I assume they learn as you teach others, fantastic! The idea of setting up your table saw for control is really good. I am 73 and have built my house (w/my own hands) raised 30+ horses and five children. been married for 50+ years to the same woman. Had a career as an engineer and designer. Was even a flyer on and off Aircraft Carriers in the Navy. I am still working my ranch and even with Heart Lung and Kidney issues, So What! I am 73. Still going strong thanks to the Lord of Creation's grace and peace. Remember "Never give up and Never Surrender" The Creator says live as "Free Men" just don't use freedom to do evil! A lesson the "so called leaders" should have learned when they were teenagers! P.S. started a Pecan Processing Business and had to design and build two of the 3 pieces of equipment from scratch. (Used a lot of Physics). May The Lord of Creation bless and keep you and yours May He look on you as a loved son and give you His Grace and Peace.
