Formula SAE is a student design competition organized by SAE International,
formerly known as the Society of Automotive Engineers. Conceived of
in 1978 at the University of Houston, the first organized competition
was held at the University of Texas at Austin in 1981 and included only
6 teams. Since then it’s grown into a major event including well over
100 teams from all over the world.
MIT Formula SAE team was started by two aspiring young freshmen in 2001
and has since grown into the current team of about 30 students. The
team has garnered recent national recognition with two back-to-back,
top-10 finishes at FSAE West in California.
2013 a new vehicle class was introduced called Formula SAE Electric.
The MIT Motorsports
team decided to change direction and design an electric vehicle to compete
in the first Formula SAE Electric competition in the US – held in Lincoln,
NE last year. The decision and hard work paid-off with a 16th place
finish out of over 120 teams at the FSAE competition in Michigan.
During development of the Electric Vehicle, the MIT team faced many
challenges including testing and optimizing their new electric motor
powered drive train. They needed to characterize their motors and turned
to the experts at Interface for help developing an electric motor test
stand. After consulting with an Interface application engineer, the
Resolution Digital Torque Transducer) with integrated couplings
was selected as the torque transducer of choice for their rigorous testing
program. Advantages of the HRDT were compact installation, high accuracy
and large overload capability.
