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.

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.

I'd like to listen and learn.

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...

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.

my sentiment exactly

Completely agree , well said👍

He's my online surrogate mentor, and he never did pay for drugs. Not once.

His face is on the other side of the pillow

@@user-ue7mw7hg7n 🤣😂 he makes all my bad thoughts turn into good thoughts, trust me, you do not want to watch his videos!!

They all will work for me

It's variable, it all depends on the candy input.

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.

@SapceDandy 94 I think nobody got that joke. But I did. Thank you 😄

Okay Vegeta.

@@dinoscheidt what's the joke lol

Oooh, could I ask you if you know anywhere I could find info on how to design high pressure, high efficiency centrifugal pumps without specialised software? I'm trying to design my own and it's really hard.
