question from @alexx7910 Thank you for taking the time to make this video! I have a question, the total moment of inertia is 22.5kgm2 and the motor allowable MOI is 1000 times less. I don't quite get the part with the maximum allowable MOI given by the datasheet, explanation needed please do reply.
Bro i am studying 3rd mechanical engineering right now this video is very useful to. Meee kindly upload more like this in every topic in partical manner
Really really thanks for this vedio sir . I badly want this vedio because I am designing roller conveyor as well as rotary table machine. Thanku thanku sir lot of love ❤.
I appreciate the clarity of technical knowledge you have while creating the video. Love your content. While calculating torque required to overcome bearing friction in second example, why did you use Torque - Frictional force (F) x Radius of bearing (R). C.G of net force is at the center, so the R is 0, no frictional force at all. What do you say about it ?
Thank you so much!! Regarding T = F X R, R is radius of the bearing. where actually bearing's rollers are making friction. so frictional force F (which is resisting the rotation) is at radius R, from pivot point (center of turn table)
Hey first year mechanical undergrad here, was happy seeing the mechanics concepts which i studied are applied here and i was to get everything. Also i would like to know why moi of the load(box) is considered?
Glad to know it helps. Yes we will have to consider the box moi as well. Because these boxes will be at rest initially. So we need to accelerate them too, same as we accelerate rollers of conveyor.
Please do a video on how to properly attach a motor to a rotating platform. For example, what goes before and after the motor, couoling and bearing. I watched your bearing videos.

I didn't get the point at 26:00. How it can be right to assume that load like its rotating and to take it as equivalent moment of inertia, if it is moving directly and has no moment of inertia in fact. Can someone explain physics behind that, please?
Instead, you would typically use the energy equivalent of the rotational and linear inertias and reduce them on the motor speed to arrive at the torque. Let me know, if you need an example
See, the belt is in contact with the surface of the pulley, so for any rotation of pulley, The load on the belt moves forward by exactly the same distance that the the pulley circumference moves, This means the load linear motion depends directly on the radius of the pulley and the angle of its rotation- if roller rotate x radian, load will move- X radian. r (if roller rotates full rotation - 2 pi. r) And the same condition will occur, when we put the load on the circumference of the pulley, right ? This is what i did here, i put the total load (100 kg as a point load) over pulley circumference, and we know the moi of a point load at distance r, here r is roller radius. But this is just an approximation calculation.
@@mastermechanicaldesignThank you Sir, now I understood the logic behind this. Beside that I want to say that I think in the real case for radius(center of mass) we must take distance from the axe of the roller to almost the center of the load(orange rectangulars). What do you think about it? Am I right?
Very nice sir , very useful, i will use this method in my design, one thing sir you have show the image of induction motor but i thing that is BLDC motor image. Please correct me! If i am wrong
I enjoyed the video. If I consider the reduction ratio, would it be correct to calculate the torque as the moment of inertia divided by the square of the reduction ratio?
For fixed indexing up to 24 stations, we use a standard indexing gearbox with an induction motor- I have used the Orbital system. But there are lots of local brands.
I'm not sure about bag. but you can surely customize t shirt, there are a lots of online t-shirt printing stores. (Here I can't publish someone else logo on merchandise, that would not be appropriate)

Nice one❤... Would like to watch more videos on fixtures, NPD, advanced GD&T etc...
Yes
Yes
No
want to videos on classical physics
Your explanation is like as sweet to understand about inertia and moment of inertia.
Thank you 😚😚
Bro i am studying 3rd mechanical engineering right now this video is very useful to. Meee kindly upload more like this in every topic in partical manner
Actually i was working on almost same problem. I'm designed the rotary table for CNC swiss lathe. Thanks for sharing!
You are welcome!

Great content brother hats off to your hard work, please link your mechanical notes so that we can make use of it
Excellent 👌👌

@kamalakannan.1971 not only example, actually I didn't understood your text, sorry. But thanks for try.

Video on chain conveyor
Excellent
Sir also guide how to give route for wiring and pneumatic pipe in rotary table. Please guide best possible ways
Noted!!
Very nice sir , very useful, i will use this method in my design, one thing sir you have show the image of induction motor but i thing that is BLDC motor image. Please correct me! If i am wrong
You are correct, the image, which is containing internal parts of a motor, is a BLCD motor.
Nice videooo
waiting for fresh new series... do you have any calculation n motor selection course. please let us know.
I will publish an ebook, soon
I am finding paid courses regarding same bro.
@@mastermechanicaldesignwow great eagerly waiting for that one🎉🎉🎉❤❤❤
I enjoyed the video.
If I consider the reduction ratio, would it be correct to calculate the torque as the moment of inertia divided by the square of the reduction ratio?
I think yes, but I would like to verify
Where did you get those values in coefficient of friction?
From bearings datasheet
For ball bearings - approx 0.02
For roller bearings - approx 0.05
Between dry finish steel plates - 0.1 to 0.5
Which type of compnay motor we have to use for roatry indexing table , If we develop in house rotary table
For fixed indexing up to 24 stations, we use a standard indexing gearbox with an induction motor- I have used the Orbital system. But there are lots of local brands.
Sorry sir but where u from take coefficient of friction value 0.5 when we use rail and lm block?
This is just for an example. For LM rail and block- coefficient of friction can be considered as 0.02 to 0.05
Super...
Thanks Sir
torque to pulling 19Nm how it does obtain sir>?
Where ? Leave time stamp
Next topic heat treatment process and hrc etc how to exactly give hrc 50 60 etc details ❤
There is already a video on heat treatment, do check that out
Is jlcmc delivery parts available in india
Yes, in india too
Can we get the t shirt with solid work printed. And also a bag with solidwork printed.
I'm not sure about bag. but you can surely customize t shirt, there are a lots of online t-shirt printing stores. (Here I can't publish someone else logo on merchandise, that would not be appropriate)
Keep it up sir 🫡
i have a feeling, we are going to become friends soon hhhhh
The cylinder will accelerate only at the start of the stroke, not throughout the whole stroke. It will accelerate and then decelerate.
Yes, maybe because air will not feed with the same speed, this is why i have mentioned - it depends on air flow rate
👍
why do you pronounce f as p and z a j and sh as s ?? great video btw
