Your speed is perfect thank you for fast info
You're welcome!
Excellent air. Thnk you.
Thanks
You do answer people's questions about passive magnetic bearings in a sort of vague way. I think many would look for a more detailed explanation of a passive system. Passively magnetic bearings are limited by their amount of pull and push forces of each magnet used in the system. You pointed this out in terms of weight as in the example of electric companies they are producing power for millions of people they need large systems where the use of active magnetic bearings make sense due to the shear weight of the system in use. Passive magnetic bearings can be used in small applications. For example you will find in many videos on TH-cam about passive magnetic bearings they use a more common needle or jewel type bearing to stabilize the z axis of a rotating system. What they don't tell you is that it can also be stabilized by the use of a tractor beam magnet configuration. But this limits the rotating portion of the system are due to the push and pull forces of each magnet making it so the whole rotor/axle part will not be stable beyond about 5 pounds or so of weight in order to achieve long term stability of the system in use with commercially available magnets. I know many might think free energy but this is not the case less friction means less maintenance not no maintenance. As pointed out in the video magnetic bearings are more efficient but not perfect as many might imagine.
Thanks for the info
For the neodymium magnets that can't tolerate hear wouldn't fly wheels be the best way to utilise them? Because the don't heat up if a magnet bearing is used in the system
all high RPM fly wheels have some type of Magnetic Bearing
Very informative
Gald u liked it
What a great explanation
Glad you think so!
Hello, I would like to acquire this type of passive magnetic bearings, could you guide me?
not really as they are very Specialized Components U need to know right place which I don't
great video.
Thanks!
Do you know the lifespans of both systems of bearings, approximately?
you have to read up on MTB of each bearings system
You’re D best
Thanks
Sir can I use electro magnetic bearing. In e-bike
not really as the cost and power requirement is huge they only makes sense in big stuff where removing friction = profit
@@s2tenglish tq sir. For responding
I am producing all kinds of spindles for machine tools in Korea. I am interested in magnetic bearing for our products.
what is the use case if there are too much dynamic loading U may not find this cost effective as cost & power draw wont be too high
Slow down. Good information but too fast. I need to see the video again.
my camera has recording limit so its hard to do but I will try
.75 speed on settings for speech understanding
ouch
1 % of 99 is greater than 1% of 100? hmmmm...
Amazing video! to the point, and loaded with info!
my bad I could not convay it well 1% loss at 99% strength is more brutal as you eat up in safety margine
Play at 0.5 speed lol
that is why YT has playback control
