Indian Railways gets on the express track with reliable motor drive solution for diesel locomotives

indian railway

Challenge

The Indian Railways needed a DC/AC motor drive solution for AC crank case motor, AC cyclonic filter dust exhauster motor, AC rectifier blower motor, AC fuel pump motor that would deliver 75% of constant torque during voltage fluctuations of 12 volt to 95 volt. It was essential that motors did not lose speed and torque while switching onto the auxiliary power supply unit while stationed.

The railway’s specific standards and high reliability requirements presented additional challenges.

Our solution

We designed a solution that perfectly matched the needs of the Indian Railway. The economical, tested solution was delivered on time to a tight deadline, and to stringent railway specific standards. In line with expectations the solution included driving AC motors with circuits for stabilized power output, surge suppression and other protective circuit designs so that motors did not lose speed and torque while switching onto the auxiliary power supply unit.

Products

GreenTech Labs offers robust and field proven custom made products for diesel locomotives. Since 2010 we’ve delivered hundreds of thousands of reliable integrated motor drive products to various companies worldwide. Most of these are still in use within demanding applications that typically have a lifespan of five-ten years.
