A Study on Electric Drive of Vehicles

A Set of devices to convert electric energy into mechanical energy and to regulate the converted energy flus according to a specific law. It is most common type drive. Electric drives may be classified to design characteristics into three types Single Motor Group and Multi motor. Single Motor electric drives and used for power tools, Simple metal working and Wood working machine tools and Household Appliances. Group electric drives are almost never used in modern Industry. Multi motor electric drives used in multi operation metal working machine tools as individual electric traction drives for rail road transportation equipment. Electric drives may also be divided into reversible and non reversible types and depending on possibility of controlling the flux of the converted mechanical energy, into uncontrolled and controlled velocity types. Interest in electric drive vehicle technologies is growing, and their development accelerating, in the Automotive industry. This growth represents a shift of focus from market entry and environmental drivers to mainstream, customer committed development. Anumber of different power train archirectures have been considered and introduced in the market for different applications. This architectures are usually classified into five cateogies Series, Parallel, Power Spilt, Voltec and Plug - in
