Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

The stop go traffic condition has become synonymous with driving in our big cities. In such a case will automatics transmission make sense to the Indian customer. Well the Indians haven?t taken to automatics like fish to water. The reason being conventional automatics always consume slightly more fuel than manual transmission and the lack of sophisticated automatics.

With the increase in traffic conjunction in the cities stop go traffic has become a big hassle with constant gear changing. In such a situation CVTs or continuous variable t ....etc

CVT-Continuously variable transmission


continuously variable transmission (CVT) is a transmission that can change steplessly through an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities. This can provide better fuel economy than other transmissions ....etc

You Can use honda Activa CVT but you will face following issues-

1. There will be coupling issue. You cannot couple a CVT with any engine. you.If you are using different engine you will have to design a coupler. same will happen with final drive. This is a difficult task, and cause lot of problem for first timer.

2. Before moving ahead make sure you will get the Ratio you desired. You will lost advantage of CVT if Ratios are not right. ....etc

Continuously variable transmission (CVT)

After more than a century of research and development, the internal combustion (IC) engine is nearing both perfection and obsolescence: engineers continue to explore the outer limits of IC efficiency and performance, but advancements in fuel economy and emissions have effectively stalled. While many IC vehicles meet Low Emissions Vehicle standards, these will give way to new, stricter government regulations in the very near future. With limited room for improvement, automobile ma ....etc

ABSTRACT
Continuously Variable Transmissions (CVT) offer a continuum of gear ratios
between desired limits. This allows the engine to operate more time in the optimum range
given an appropriate control of the engine valve throttle opening (VTO) and transmission
ratio. ....etc
