Thanks for the heads up! My video is already more than 1 year old so this technology may actually be a variation of my idea and not the other way. Do you know when those products appeared on the market?

True, the whole "D-Drive" mechanism could be reduced to a simple differential where one half is driven by a secondary electric motor which is just a replacement for a friction disc i.e. poor efficiency under useful torque. Regarding my invention, unfortunately lego technic lacks the...

Not inherently, but in practice they are (about 70% efficiency for belt drive even when it does not slip). Designing them to transmit high torques makes them really inefficient.

As far as I know that is not a CVT in itself but rather an integrated power train and it requires a battery to work. It is a hybrid drive, not a CVT that you would just connect to an ICE and freely adjust the ratio. I know that right now it's not suitable for automotive. But I think it's...

Here it is, a rough working mechanism to help you better understand the principle :smile:

I think Newton sucks :rolleyes:

Yes, you cannot understand without audio. That's the key. On a certain portion there must be no electromagnetic force, else the integral of force on the entire coil would be 0. No matter how you place the magnet or the coil, without such shielding or without current switching (with an...

My new electric motor is based on exactly this thing (part of the coil is in the cavity of a permalloy). https://www.physicsforums.com/showthread.php?t=663657

Sorry, forgot to embed the video..

[url]K-yyJF-kTMw[/youtube]I'm not 100% sure it works because I haven't built a physical prototype yet. Though, the only problem that I see at the moment is the low power density potential and the low efficiency. Meaning that it WILL NOT REPLACE conventional brushed or BL motors. I would really...

https://www.youtube.com/watch?v=nOzRzmfh884 Unlike other CVTs that use belts or steel balls, this is obviously not friction based therefore it should be more efficient and be able to withstand higher torques without any risk of slippage. The main problem that must be solved is the trepidation...
