The Ultra Urban 9/9 AC electric buses also come equipped with regenerative braking system, new-generation telematics and a high-security Intelligent Transport System (ITS). The zero-emission buses, which have been supplied under the FAME II initiative, offer enhanced comfort, plush interior lighting, safety and clean energy with noiseless operations. These fully electric buses can generate a maximum power of 328 hp and a maximum torque of 3000 Nm. 'The delivery of these buses will further cement our fruitful association with AJL and foster eco-friendly mass mobility in Ahmedabad,' he added. Rohit Srivastava, Vice President of Product Line for Buses at Tata Motors, said, вЂњWith a steady commitment towards modernising public transportation and integrating sustainability in the designing of futuristic vehicles, Tata Motors has led the move towards electric mobility in the country.' Tata Motors had bagged the offer of delivering 300 electric buses to the AJL two years ago. One of the main concerns with permanent magnet motors is that they often useВ rare-earth materials, which are controversial because of health risks and geopolitical issues.В But not much is known about the design of the Model 3 motor at the moment.After delivering the 60 electric buses, which have a capacity to accommodate up to 24 passengers each, Tata Motors said that the company will also help setting up EV charging infrastructure for these buses as well. Tesla is still far from reaching its cost target for the Model 3, but they can say вЂmission accomplishedвЂ™ for efficiency since the Model 3 is one of the most efficient vehicles on the market, according to the EPA. It sounds like the decision was driven by efficiency and costs. Quantitatively, the difference is what drives the future of the machine, and itвЂ™s a tradeoff between motor cost, range and battery cost that is determining which technology will be used in the future.вЂќ This is because for the specification of the performance and efficiency, the permanent magnet machine better solved our cost minimization function, and it was optimal for the range and performance target. So, as you know, our Model 3 has a permanent magnet machine now. Both make sense for variable-speed drive single-gear transmission as the drive units of the cars. Induction machines have perfect flux regulation and therefore you can optimize your efficiency. вЂњItвЂ™s well known that permanent magnet machines have the benefit of pre-excitation from the magnets, and therefore you have some efficiency benefit for that. The automaker recently confirmed that they are building an electric motor R&D group in Greece to tap into strong local electrical engineeringВ talent.ДЄt the Coil Winding, Insulation & Electrical Manufacturing Exhibition (CWIEME) in Chicago,В Laskaris made a rare comment about TeslaвЂ™s decision to use aВ permanent magnet motor in the Model 3 instead ofan AC induction motor, like in Model S and Model X. We recently reported onВ Laskaris because he went to school atВ the National Technical University of Athens in Greece, like several other top motor designers at Tesla. Now, TeslaвЂ™s principal motor designer,В Konstantinos Laskaris, explains the logic behind the move. Tesla made a significantВ change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to aВ permanent magnet motor.
