The process of applying brakes and reduce the speed of any moving or rotating equipment can be termed as braking. Mechanical Braking Electrical Braking Types of Electric Braking Rheostatic / Dynamic braking. Regenerative Braking....
Tractive effort: It is the effective force acting on the wheel of locomotive, necessary to propel the train is known as ‘tractive effort’, Ft. The tractive effort is a vector quantity always acting tangential...
The speed-time curve of a main line service is best and most easily replaced by a trapezoid. Since the area of the speed- time curve represents the total distance travelled hence the areas of...
Crest Speed: The maximum speed attained by the vehicle during the run is known as crestspeed. Average Speed: The mean of the speeds from start to stop i.e., the distance covered between two stops...
A speed time-curve is a graph showing the variation of speed with respect to time. The curve drawn between speed and time, taking speed on the Y axis and time on X-axis, is known...
classification of Electric Drives Individual drive:- If one motor is used to drive one load. Group drive:– When several machines are run on one shaft and the shaft is driven by a single motor...
An electric drive can be defined as an Electro-mechanical device for converting Electrical energy to mechanical energy to impart motion to different machines and mechanism for various kinds of process control. It is the...
The process of moving any vehicle either in streets or in railway systems is called Traction. The system of traction involving the use of electricity is called electric traction. Electric traction is meant locomotion...
