The electrical transmission of variable speed which makes it possible to change the output speed range ( minimum- maximum ) certain fixed period or be modified to be able to achieve their . This type of Electro who is also known by the names of variator due to the adjustable output is used to change round . In this paper , functional and design issues that will be assessed a review electrical transmission of variable speed. Relations also designed to improve the performance and efficiency from the perspective offered. Power generation system in most variators engine designed , via steel shot , whereas in the new system was designed , has oil pressure is used to generate power that the power production in constant speeds, provide the required torque.
In other words at this system, according to its hydraulic and use of oil instead of gas flows through the issue of excessive wear and tear gas in the cyclic changes , which resulted in the failure to provide the torque to was gone . The results show that speed control in both directions of rotation output, high starting torque and high efficiency is 90%
