This is one of the best videos I have seen on TH-cam. It is clear, concise and only long enough to cover the actual topic without embellishment. I have seen other videos showing the relationship of speed and torque but this is far and away the best. It is clear and informative, and the video presentation is perfect. For once the mysterious TH-cam algorithm popped up a winner. Congratulations.
here I'm watching from Egypt and that was so far the clearest video that explained the relation between torque and rpm cuz it's practical. I'll recommend u to my fellows, thanks professor
Muchas gracias, de verdad muy ilustrativo y justamente algo asi andaba buscando para mas o menos caracterizar un destornillador electrico que estoy pensando hacer pero que tenga la opcion de torquear el tornillo, no se si sea algo muy ambiocioso pero bueno, la maxima es aprender. Saludos desde Tachira, Venezuela!!!
thanks for this experiment, we could have strengthen our thought over torque more by your experiment, from this experiment, at each loads, the motor was able to lift them up, and it gives RPM and weights (which is used for torque). but we are wondering that from the point of motor, it should be told to produce more torque that can spin the pully and lift the given weight. When the explanation comes with F X d, it could confuse a concept that the motor might generate the torque by weight of loads. But it's opposite. Torque (of motor) = loss ratio of pully * radius of pully * lifted weight * 9.81kg.m/s2 at certain RPM, The torque is input, and it should exceed the torque which is caused by weight for spinning. and this torque could not being representing nominal torque, but for selectors are watching motor's continuous torque that can be controlled without a risk or harm to motor. I'm trying to put my energy to understand the torque in experimental ways, hope this can helps a bit more. In final, I want to test 400Nm nominal torque motor with the similar experiment that you showed (don't have dynamo unfortunately), so many things in doubt.
this is very nice video but, most of your video is playing with the tachometer, while interesting part going from bucket to mass to torque you just run through. Not saying that you did not explain it. You did, though I find it more interesting to stay and go through bucket, mass, weight, force, torque for bit longer time. Minor detail shared from my subjective point of view. Thank you for the video! Very nice, I liked it.
Thank you for this video and others I have watched. I would like to explore how to make a PMDC motor model based on experimental data. I would like to build a model for the 130 PMDC motor which also has three poles ... suggestions?

The best and simple explanation I have ever had about torque conversion with DC motors ❤❤❤ thanks

This is the best video for the topic relation between power and torque which I was looking everywhere. Finally understood it.

Great video. You got to the relevant points very quickly and provided both theoretical and practical knowledge.
Best video and very clear explanation.
I just wanna thank you soo much, you are a excellent teacher!

Thank you for this amazing info.
Best demonstration. Thanks
Very interesting, I like it!
Simples e objetivo !
thanks a lot for this video
Great video.
Can you tell a way to apply dynamic load to the motor and then observe its performance?

in teory pmdc is has same caraktersitic with shunt dc motor, so it has 'constan' speed over varied load

It would be extremely informative, if you could repeat this same experiment for 10Nm Motor used in 2 wheelers
Holy cow. Super informative. Subd 🙂
Thank you. Hope you found these series useful.
Your bench supply is current limited, thats why the voltage drops.
Yeah ..isn't that a flaw in the experiment? By using a current limited psu we are not really measuring correct data right?
Correct
@@fabiofoltran4361 it was more about the presentation of the method I understood.
guys what is that device that he uses to measure rpm?
Tachometer
Is there any other way that is easy?
It's a gearmotor.
información de alto valor! muchas gracias por compartir.
