Still in improvement, the magnetic CVT transmits torque using a non-Make contact with magnetic coupling.[30] The design makes use of two rings of everlasting magnets with a ring of metal pole items involving them to make a planetary gearset working with magnets.
In outcome, you’re switching gear all the time. There’s some alternative ways of accomplishing variation in pulley measurements, but the elemental theory is usually a similar.
