Design, Development and Testing of Traction Motor Speed Sensor used in Indian Railway Locomotive

In Indian railway locomotive, the traction motor speed sensors are used to measure the speed of the traction motor and control the brakes applied on the machines. These play a vital role in the train state control, stability of the motor and monitoring of the systems. In the past, it seen that there are no test benches reported for the traction motor speed sensors. It is also seen that there are speed control methods implemented using different controllers such as FPGA, MATLAB on DSP kits. Henceforth this work can be improvised by creating a test bench for the traction motor speed sensor. The creation of test benches, controlling the speed of the traction motor and performance of the traction motor speed sensors is executed on railway locomotives which is shown in this paper. This work is done using controller and hall effect sensor as feedback circuit given to the controller. So, it is seen that there can be an ease of conducting an experiment for traction motor speed sensor using main controller board.
