Could using magnets to break and start be a solution to reduce the heat generation ?

• CorrectHorseBat 4y ago
  Using magnets will release exactly the same amount of heat since energy cannot be destroyed (unless you mean by that using regenerative braking, that does work since you can "recycle" the energy)

  That's effectively what motors and regenerative braking are (just the magnets are in a circle!)
