Discussion Overview

The discussion revolves around the concept of a magnetic continuously variable transmission (CVT) belt that could be driven electromagnetically. Participants explore various strategies, technologies, and implications of implementing such a system in automotive technology.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that a magnetic CVT belt motivated electromagnetically is an inevitable evolution in automotive technology and seeks ideal implementation strategies.
  • Another participant questions the meaning of "motivated electromagnetically," proposing it refers to movement driven by electromagnetic forces.
  • Some participants propose alternatives to mechanical gears, mentioning concepts like Hybrid Synergy Drive and Electric Variable Transmission (EVT) as potential frameworks.
  • A suggestion is made to consider an electromechanical transmission that drives a generator to supply power to a brushless DC electric motor, eliminating mechanical coupling.
  • One participant introduces the idea of using a Faraday disc with electromagnetic clamping instead of fluid pressure, proposing that increased current would enhance the grip.
  • There is a discussion about the Toyota hybrid setup, which utilizes a combination of an internal combustion engine and electric motors to create a CVT, prompting questions about the necessity of a belt in such systems.
  • Another participant acknowledges a lack of experience with hybrid transmissions but expresses interest in learning more about existing technologies.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the implementation and necessity of a magnetic CVT belt, with no clear consensus on the best approach or technology.

Contextual Notes

Some discussions involve assumptions about the definitions of terms like "motivated electromagnetically" and the feasibility of various proposed technologies, which remain unresolved.

TL;DR
The adaption of electromagnetic propulsion to CVT transmissions for hybrid advancement...
What would be the best strategy to make a magnetic cvt belt that could be motivated electromagnetically? I think this is an inevitable step in the evolution of automotive technology, so what would be the ideal way to implement it? A starter through the primary pulley to start the ice or move the vehicle in emergency mode... coupled to a drive-train.

I think it means "moved electromagnetically". Not "motivated" in the way we are used to using the word ("go for it belt, you can do it!").
 
If you mean an electromechanical transmisison instead of an electromechanical belt, then how about driving a generator to supply power to a BLDC electric motor. There would be not mechanical coupling at all, just electric. In principle, that is how hybrid electric cars work.

Yeah, I've replaced an I.C.E. with no starter, the transmission (with the coil inside that drives the engine or the wheels, or the battery) needs to have a continuously variable armature.
 
I'm thinking about the Faraday disc... is that the right name? Like a coil with a contact but brush-less. Electromagnetic clamp instead of fluid pressure. The more amps you pump through, the tighter the clench. No more spring tension on the ratio piston to fight.
 
Why use a belt at all? Toyota's hybrid setup uses a combination of an internal combustion engine and 2 electric motors to create a CVT that is beautifully simple and reliable.

Well now that's something I wasn't aware of! I've never rebuilt a hybrid transmission, yet, so I don't even have much insight into what has been done already... I will certainly look into it, thanks!
