Introduction to Traction Systems. Traction batteries also called electric vehicle battery EVB are used to provide motive power for electric or hybrid vehicles.
Traction batteries also called electric vehicle battery EVB are used to provide motive power for electric or hybrid vehicles.
What is meant by electric traction. Electrical Traction System. The act of drawing or pulling by power is known as traction. This system uses DC series motor or single phase AC series motor or a three-phase induction motor.
The electrical input is directly fed to the motor and torque is generated. Electric traction 1. Electric TractionPresented ByPiyush Kumar10EEE023 2.
Contents What Is Electric Traction A Brief History To Electric Traction Voltages Used For Electric Traction In. What is electric traction Electric traction is meant for locomotion in which the driving. Introduction to Traction Systems.
By electric traction is meant locomotion in which the driving or tractive force is obtained from electric motors. It is used in electric trains tramcars trolley buses and diesel-electric vehicles etc. Electric traction has many advantages as compared to other non-electrical systems of traction including steam traction.
Electric traction involves the use of electricity at some stage or all the stages of locomotive movement. This system includes straight electrical drive diesel electric drive and battery operated electric drive vehicles. According to European standard IEC 60254 1 lead acid traction battery are used as power sources for electric propulsion in applications which include road vehicles locomotives industrial forklift trucks and mechanical handling equipmentMHE.
The traction battery pack can be made of 2 volt cells or 4 6 8 and 12V monoblocs Fig1. There is no stipulation in the traction battery manufacturers Europe traction battery market on the internal construction of the traction. High Voltage Electric Traction.

Traction batteries also called electric vehicle battery EVB are used to provide motive power for electric or hybrid vehicles.
The major emphasis on traction battery design is the necessity of a high capacity to weight and volume ratio since the vehicle must also carry its power source. Traction batteries are frequently deep cycled and require a fast charging rate for use usually within 24 hours. Typical applications are motive power for fork lifts and electric carts.
In very simple words the systems which control the motion of the electrical machines are known as electrical drives. A typical drive system is assembled with a electric motor may be several and a sophisticated control system that controls the rotation of the motor shaft. Now days this control can be done easily with the help of software.
So the controlling becomes more and more. Traction motor refers to a type of electric motor. A traction motor is used to make rotation torque on a machine.
It is usually changed into a straight line motion. Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric locomotives. They are also used in electric vehicles such as electric milk floats elevators and conveyors.
12 What do you mean by schedule speed in electric traction. The ratio of distance covered between two stops and total time of run including time of stop is known as schedule speed. Schedule speed Distance between stops in kmActual time of run in hours Stop time in hours The schedule speed is always smaller than the average speed.
Application Traction motors. One of the major application of electric drives is Electric Traction. Ie to transport men and materials from one place to another.
Various types of Electric Traction are i Electric trains ii E lectric buses iii Tramstramways. Traction Batteries for EV and HEV Applications. Battery Requirements for Typical Traction Applications.
Traction applications have traditionally been jobs for Lead Acid batteries but the limitations of Lead Acid batteries together with the high cost of alternatives have in turn limited the range of potential battery powered traction applications. System of electric traction Mechanics of Train Movement. Speed- time distance- time and simplified speed-time curves Attractive effort for acceleration and propulsion effective weight train resistance adhesive weight specific energy output and.
OR Electric traction means a locomotion in which the driving force is obtained from electric motors. Electric traction will continue to play a dominant role in the Railway since it is an environmentally clean technology compared to diesel traction and also its running cost is low. There are many advantages of electric traction over other forms of locomotion.
An electrical section is a collection of elementary electrical sections section breaks air switches and paralleling stations between a substation and a switching station. At each substation utility-supplied single phase power is transformed and injected into the two electrical sections terminating at that substation. There are eight electrical sections in the system two for each substation.
