BHU BHU 2009 IT BHU Develops Cheaper Motor Technology



PTI reported that Linear Induction Motor rail metro system developed by the Banaras Hindu University can save more than INR 100 crore per kilometer if adopted for the proposed metro project here in place of the conventional metro system including used in Delhi metro.
The LIM system already running in Japan as a transport method has been researched by the scientists of BHU and awaits a proper consideration by the authorities concerned to apply the technology as a new form of metro rail system in the country.

The LIM system once used will lead to a major cost reduction as the tunnel diameter required for this system is as low as 4 meters compared to 6.2 meters for the conventional metro system. Also, in the absence of adhesion driving and major rotary parts, the LIM system will require reduced maintenance which has become a major problem in the country.

Mr SN Mahendra head of electrical engineering department of Institute of Technology BHU said that “The LIM technology, if adopted will prove to be 30% to 40% cheaper than the Delhi metro.”
