Formula Student Electric
Students develop electric racing car
Stöber Antriebstechnik has been supporting Rennschmiede Pforzheim, which regularly takes part in Formula Student, since 2014 - until now with a combustion engine vehicle. From 2020, the team will also compete in Formula Student Electric. The drive specialists are providing motors, gearboxes and inverters for the new race car.
The racing team at Pforzheim University has been around for ten years. Since then, the students have regularly celebrated successes on the world's major racetracks with their combustion-engined vehicles. Every year they put a new car on the wheels. The speedster for this season was named "Emerald". In 2020, they want to prove that the team not only has gasoline in its blood - but also plenty of electricity. The racing team will then take part in Formula Student Electric (FSE) for the first time. But before they can take on this new challenge in the coming season, they first need to develop a competitive vehicle.
Switch to electric drive
"Whether fuel or electricity - none of this would be possible without sponsors, supporters and technology partners," says Nadine Böckle, Team Manager Sponsoring at Rennschmiede. One of the financial supporters since 2014 has been the company Stöber, which is also based in the Goldstadt. "At the beginning of this year, one of our students wrote his bachelor's thesis at Pforzheim University on the subject of 'Designing the drivetrain for a Formula Student vehicle'," says Nadine Böckle. "That's how we got in touch with Stöber. When the team decided to take part in the FSE next season, we intensified our collaboration." Stöber supports the team as a platinum sponsor, as the drive specialist now also supplies tangible technology for the race car: two rear engines with gearboxes and the necessary drive controllers. In addition, the engineers have a great deal of know-how to further develop these important components to meet the requirements.

Sensorloser Servomotor
Der Leanmotor von Stöber Antriebstechnik ist ein Synchronmotor, der Eigenschaften der Reluktanzmotoren und permanentmagnet erregten Servomotoren zusammenführt. Damit erschließen sich Vorteile: Reduzierung der TCO, des Installationsaufwandes und Betriebskostenreduzierung durch hohe Wirkungsgrade bis 96 Prozent.
The racing forge has been in the development phase since September. The students are currently working on the concepts and implementing them in the CAD system. Once this phase is complete, the production partners receive the 3D drawings and can get started. "Once we have completed our exams at the university in February, we will then devote ourselves entirely to production," says Böckle. The racing team plans to present the new e-car to the public in late spring 2020, after which the team will test the vehicle extensively - including under competitive conditions at various events. "We're particularly looking forward to Hockenheim, of course," says Nadine Böckle. "We practically have a home game there." dsc
