Positively Infinitely Variable (PIV) chain drives are distinctive in which the chain positively interlocks While using the conical pulleys. That is obtained by possessing a stack of many small rectangular plates in Every single chain connection that will slide independently from facet-to-aspect. The plates might be pretty slim, about a millimeter thick. The conical pulleys have radial grooves. A groove on a person aspect of your pulley is fulfilled with a ridge on the opposite side and so the sliding plates are pushed forwards and backwards to conform to your pattern, properly forming teeth of the right pitch when squeezed amongst the pulleys.
When the facility output is too small, the generator is disconnected, along with the Power is saved while in the flywheel. It is only if the speed on the flywheel is sufficient the kinetic energy is transformed into electricity, intermittently, with the speed essential by the generator.
