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.

Remember in general when you increase power output you also increase heat generation. He could have used some kind of heat sink but I would have used water to cool the system.

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.

[@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.

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.

[@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.

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.
