DESIGN AV ELECTRISK MOTOR FOR FORMULA STUDENT
MetadataShow full item record
Revolve NTNU is a student organization that each year design and build a formula race car to participate in the engineering student competition Formula Student. Since its birth in 2010, Revolve NTNU has developed rapidly both organizationally and technologically. After achieving titles as best newcomer (FSUK 2012) and best Nordic team (FSUK 2013) with conventional combustion engines, the team took a big technological leap in 2014 and switched to an electric powertrain. The same year Revolve NTNU finished as the best rear-wheel driven electric vehicle (FSUK 2014). In 2015 the 2014 concept was refined and finished as 4th overall (FSA 2015). To keep up the progress in the future and bring the battle to the decade-long experienced top running teams, Revolve NTNU has decided to change the powertrain layout to a four-wheel driven system with hub-mounted electric motors. This opens new possibilities for regenerative braking, torque vectoring control and overall increased acceleration. Due to very limited availability of suitable motors on the commercial market, the organization has initiated a research & development project. The goal is to develop an electric motor prototype tailored for use in Formula Student within a limited budget.
