- It’s a brushless AC motor run on 220 Volt , We have removed the lock ,so it can rotate in either direction (clockwise or anti-clockwise )
The cylindrical magnet is having multiple Pole , it synchronise with AC current
Due gear it has very low rpm but tremendous torque, you can’t stop it using hands - วิทยาศาสตร์และเทคโนโลยี
the guy sleeping on the floor doesn't look too interested.
this is the first time i have seen an application of the theories i am studying and it's actually useful 😃
Thank you for the comment
@@MADABOUTSCIENCE1972 are you all in class 12?
Class 10 , 11 & 12
vraj shah are you also in class 12?
@@MADABOUTSCIENCE1972 yes
its helpful
thanks
How we will open upper one
My teacher told us to be wary of someone saying "Catch!" in electronics class because it may be a charged capacitor. I guess people used to charge them just enough to give you a small zap. These days you might be kicked out and/or face legal consequences.
But it is safe
Safety is first priority
You are absolutely right!
Thank you very much for the comment
Great 👌12th class
Thank you
May motor is not rotating. Whats the cause? Is it the motor or capacitor. It vibrates only. Thanks
It rotates , you can observe it in the video
This ac motor dimmable or not dimmable ?
It’s
How shall I fix the plastic box to its shaft ?
It is actually gear box
Can you tell me motor model also specifications i want order it
I think it’s available on Amazon
Search ‘Synchronous Motor’
How to make this motor rotate in only one direction? Thanks.
Putting lock for one side rotation
@@MADABOUTSCIENCE1972I am so sorry, but how to put the lock?
The lock was already there , we have removed it for rotation in either direction randomly
@@MADABOUTSCIENCE1972 ooo .... Ok. Thanks.
How much weight capacity has the 4 watts motor can carry?
I did not check, but the torque is too high in slow motion, its weight capacity should be much more
@@MADABOUTSCIENCE1972 maybe it can carry 10kilos?
Yes I agree I think so
@@MADABOUTSCIENCE1972 you haven't tried sir?

How can i run only cw rotation?
By locking anti-clockwise, I have removed the lock
@@MADABOUTSCIENCE1972 Ty i removed today too. Its turnin cw
@@MADABOUTSCIENCE1972where the location of anti clockwise unit, actually?
@@fredmeyer9481@MADABOUTSCIENCE1972w here the location of anti clockwise unit, actually?
How to remove the lock
there is no lock.
This is a small motor from microwave oven.
They will turn direction if you switch em on and off.
Just try it.
You can check a working microwave oven to see it as well.
Put something on the turning table which will prevent the table from turning a full circle.
So like a clamp or something, that makes sure the plate will only be able to turn a bit and then get stuck. This motor will then automatically switch the direction of rotation.
It will start to turn the other way around if it gets stuck.
I guess to prevent the motor from burning out.
You can try it.
Just fix such a motor to a piece of wood and use a big wrench or pliers or something to stop it from turning. You will feel it will start to turn the other way.
How we can reverse the direction
Applying lock in one direction
In one of my application i need to turn the shaft for 20 sec in clockwise direction and then 20 sec in anticlockwise direction.please help.
But if you arrange the lock with timer on either side , I think it’s possible
@@MADABOUTSCIENCE1972 u want to say mechanical lock after a fixed degree of rotation on either side
sir, if you want to joke with the motor, do not let someone touch the wires with both hands.
The shock will go through his body and through his heart.
He can do it with 1 hand. Holding both wires.
He will still get a shock, but less dangerous.
Will not go through the heart.
I am not an electrician but this i know.
Sure, it is small shock, but if he holds the wires and you turn fast and keep turning fast, he may get too much through his heart.
Dangerous
Yes you are right
But we have taken care of it
You have good knowledge and good interest in scientific world, I appreciate it
& thank you very much for the comment, I like it, God bless you!!
@@MADABOUTSCIENCE1972 to you the very same, sir.
And i watch ElectroBOOM channel. He is funny. He does tricks with electricity as well. Funny stuff. He shocks people also.
BUT, he does it the safe way.
He seems to be an expert with electricity stuff.
Take care and thanks for the reply. And keep making videos if you want. They are good and funny.
@@MADABOUTSCIENCE1972 btw, touching 2 wires with 2 hands, it is logic that the electricity will go through your body.
Because electricity goes in a loop. A circuit.
So if you hold 1 wire in 1 hand and another in the other hand, your heart is in between.
This is not so much too do with knowledge. More like logic thinking. :)
Again good day sir. You have another fan checking your videos
Thank you very much again
May motor is not rotating. Whats the cause? Is it the motor or capacitor. It vibrates only. Thanks
Here the cylindrical magnet is havin 8 pole , it is not common cylindrical magnet
that is my problem too...its only vibrate no rotation...
