An overview of the research work at the Electric Motor Technology Research Center

With the current need to reduce reliance on fossil fuels, vehicles and other forms of machine that rely on gas, fossil fuel powered engines has become a key target for electrification. Building electric vehicles or machineries powered by electric motors is now under the spotlight than ever, and a symbol of a new and greener future. The Electric Motor Technology Research Center (EMTRC) was established in 1999 to develop motor-related technologies and support the automation industry in Taiwan. The Center focuses on multiple projects falling under three broad themes – motor technologies, magnetic 3D printing and providing motor and magnetic characteristics measurement services. The EMTRC aims to provide efficient mechanisms for the smooth transfer of motor related technologies from academia to industry; assisting local or global companies in building their own expertise, developing technical collaborations with industry and other research institutes in Taiwan and strengthening the relationships with other international organizations.

Application Specific

In the present scenario, the reduction of greenhouse gases is mandatory in order to create a better environment. Since the pollution levels are rising at an alarmingly high rate the need to reduce the green-house emissions is of utmost importance, to make the earth a better place to live in. usage of fossil fuels for transportation is a major cause for pollution and emission of harmful gases into the atmosphere. Studies show that in 2017 alone an average of 1873 metric tons of Greenhouse gases was released into our atmosphere by the transportation sector alone. This level of pollution continues to accumulate over the years causing devastating changes to our atmosphere and in turn gravely affect our climate destroying our habitat and threatening our survival. The resulting climate changes and its unprecedented fluctuations that have been observed stand to prove that pollution is not something to be ignored the slightest. To overcome this, one of the best first steps to start with prefers Electric vehicles over the conventional Internal Combustion Engines. By switching over to Electric vehicles the pollution levels can be controlled to a greater extent. Due to the relative ease of manufacturing and application specific interest cause the electric drives to be used in different applications and over the years various electric drive systems like DC, Permanent Magnet Synchronous Motor(PMSM),Brushless Direct Current Motors (BLDC)and switched reluctance motors (SRM)were developed. But each motor had its own advantages like better torque curve, better efficiency, lower power consumption and limitations like commutation issues, triggering, shorter life-span, high maintenance, more cost etc. which made it application specific rather than being all purpose. Different type of electric motor systems had different advantages that made it a better choice in specific applications. Even though this limited the use of these systems, this situation allowed the electric motor system to evolve into many types, each with their unique application in mind. This gives us an opportunity to have a vast selection of systems in front of us and enable us to choose the best system that meets our requirements. This paper reviews the different types of motors used in Electric vehicles based on the discussions and conclusions of various reputed journals consumption.

Transportation is the second-largest sector contributing to greenhouse gas emissions due to CO2 gas generation from the combustion of fossil fuels. Electric vehicles (EVs) are believed to be a great solution to overcome this issue. EVs can reduce CO2 emissions because the vehicles use an electric motor as a propeller instead of an internal combustion engine. Combined with sustainable energy resources, EVs may become zero-emission transportation. This paper presents an overview of the EV drive train types, including their architecture with the benefits and drawbacks of each type. The aim is to summarize the recent progress of EV technology that always continues to be updated. Furthermore, a comparative investigation on energy density and efficiency, specific energy and power, cost, and application is carried out for batteries as the main energy storage. This discussion provides an understanding of the current development of battery technology, especially the batteries used in EVs. Moreover, the electric motor efficiency, power density, fault tolerance, reliability, and cost are also presented, including the most effective electric motor to use in EVs. The challenges and opportunities of EV deployment in the future are then discussed comprehensively. The government regulation for EVs is still a major non-technical challenge, whereas the charging time and battery performance are the challenges for the technical aspect.

Energy Companies

By transforming patterns of travel and work around the world, the COVID-19 pandemic is accelerating the transition to renewable energy and the decline of fossil fuels. Lockdowns brought car commuting and plane travel to a near halt, and the mass experiment in which white-collar employees have been working from home may permanently reduce energy consumption for business travel. Renewable energy and electric vehicles were already gaining market share before the pandemic. Under pressure from investors, major energy companies have started writing off fossil fuel reserves as stranded assets that are no longer worth the cost of extracting. These shifts may indicate that “peak oil demand” has arrived earlier than expected.

The burgeoning area of plant genetics may hold the key to overcoming some of the most pressing environmental challenges. For example, crops can be genetically improved to make them better able to adapt to climate change, while genetic engineering of crops could help to address food security challenges. As such, a comprehensive understanding of plant genetics may enable humankind to make headway in addressing climate change and resulting challenges. Research in this area is therefore paramount. Research work undertaken in the Plant Transgenic Design Initiative (PTraD) in the Gene Research Center (GRC) within Tsukuba Plant Innovation Research Center (T-PIRC), located at the University of Tsukuba in Japan, is focused on plant sciences and biotechnologies. The PTraD is the centre of excellence in plant biotechnology research in Japan, shedding light on plant genetics and how this can be harnessed to solve environmental challenges such as climate change.
