SOLAR SPEED: Stanford Solar Car Races Coast-to-Coast Down Under
Stanford's Solar Car
As a group of eager Stanford students awaited the announcement that would detail this year's engineering challenge, chatter among the group predicted that 2013 would be most formidable to date. And, being some of the best and brightest, it should come as no surprise that they were correct.
The mission they were given was to design, build, and pilot a racecar that could compete against some of the top racing teams on Earth. Not only must this vehicle survive, but it would have to win a transcontinental endurance race straight through the heart of the Australian Outback. And, there was the kicker: their racecar would have to complete the entire 1850 mile voyage on less than one gallon of gas. Surprisingly, this absurd fuel restriction was the only part of the challenge that did not raise an eyebrow. It was actually expected. Because these students are the Stanford Solar Car Project (SSCP) and their mission is the 2013 World Solar Challenge. And everyone in this contest knows that being the fastest without a drop of gasoline is the only path to victory.
The SSCP set out to make the motor within Xenith the most powerful and efficient to date.

And, based on models and simulations, it appeared their new design showed promise to deliver. But, theory alone cannot satisfy a team that is hungry for a win- this critical component would need to prove itself empirically. Only through direct measurement could the team refine the acceleration, speed, and energy economy Xenith would ultimately command on race day.
The SSCP team wanted to add a clever twist to their dynamometer (dyno): implement one of Xenith’s regenerative brakes as its energy absorber. This setup would allow them to simultaneously study the efficiency of their regenerative braking system while testing their motor. But it was unclear if such an improvisation could be made to this standard. To gain perspective on if this approach could be realized, the SSCP Team called on the experts at FUTEK Advanced Sensor Technology.
Consulting with Solution Engineers at FUTEK made it clear that their dyno would need a TRS605 Rotary Torque Sensor as the center of its measurement system. The TRS Series sensor integrates a rotary encoder with a freely spinning torque transducer ...

Assembly Tool:
Miniature Torque Screwdriver
FUTEK's Miniature Torque Screwdriver is an auditing/assembly tool used to ensure that the torque applied is always proportional and never extravagant to a fixture. Our engineers developed this tool knowing that disproportionate torsion may result in the loosening of a screw during operation. Whereas, extravagant or excessive torque applied to a screw can result in permanent damage.
The combination of the TAT200 with FUTEK's IHH500 Display offers users an industrial assembly tool. This tool informs operators (per specified set-points) by alarm when over torqueing occurs. Many manufacturing processes utilize this tool for efficient production assembly.

IPM650 Benefits and Features
IPM650 Benefits & Features
FUTEK’s latest Panel Mount Display, the IPM650, takes high-accuracy measurement to the next level. Compared to the specifications of the former IPM500, the IPM650 has a sampling rate of 4,800 samples per second. Additionally, the IPM650 offers a 24 Bit internal resolution and up to 20 Bits of noise free resolution. Watch this video to learn more about the benefits and features of the IPM650.
This Month's Highlight
Cross Reference
Are you considering switching from another sensor manufacturer to a FUTEK? If you find yourself in this boat, our team developed a "Cross Reference" utility tool to help our customers find relatively equivalent replacement models. The tool looks at other manufacturers' model specifications and brings forward the closest FUTEK model in comparison. Should you have any questions about suggested models, our application team is available to answer any questions.
