A teenager who designed an electric motor without rare earth magnets

I don’t think anyone can deny that today’s young people are very smart. Some young people can use their time effectively. A teenage boy living in Florida spends his time working on engineering projects.

The boy named Robert Sansoni was only 17 years old. In his spare time, he has created at least 60 engineering projects, including high-speed running shoes. The latest project is an important electric motor design for electric cars.

About (2) years ago, Robert saw a video about the advantages and disadvantages of electric cars and became interested in electric cars. After watching the video, I realized that most electric car motors require magnets made of rare earth components, which can be expensive.

Robert heard about a synchronous reluctance motor, a type of electric motor that does not use rare earth components. But this type of motor uses pumps and fans and is not powerful enough to be used in electric cars, so he set out to find a solution to this problem.

After a year of research, Robert created a small version of the synchronous reluctance motor that had a larger rotation, or torque, and efficiency than the existing motor. Plastic, wire, It took 15 tries to get the motor made easier with the steel blades.

Its new electric motor design generates nearly 40 percent more power and is more efficient. Specifically, its engine is 39 percent more efficient (than current engines). According to Smithsonian Magazine, 300 revolutions per minute (RPM) is 31 percent more efficient, and 750 RPM is 37 percent more efficient.

Robert’s design won first prize at this year’s Regeneron International Science and Engineering Fair (ISEF) competition with a $75,000 prize. His design still needs to go through the next phase of testing before it reaches car companies. Robert hopes his motor will one day become the design of choice for electric cars.
