Interface Torque Transducer Used in MIT Motorsports
SAE Electric Race Car
September 26, 2013
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.
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.
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 HRDT (High
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.
