17-Year-Old Designs Futuristic Electric Motor Without Rare-Earth Magnets That Could Transform Electric Vehicle Industry

Sansone worked hard over the course of the year and created a prototype of a unique synchronous reluctance motor

Sansone created Electric Motor without Earth Magnet

Sansone's interest in electric vehicles piqued a  couple of years ago when he came across a video about the advantages and disadvantages of electric cars

Motivation of Sansone

After watching the video, he realised that most electric car motors require magnets made from rare-earth elements, which can be costly.

Motivation of Sansone

“I have a natural interest in electric motors. With that sustainability issue, I wanted to tackle it, and try and design a different motor,

Sansone told Smithsonian Magazine.

He had heard of a type of electric motor the synchronous reluctance motor that doesn’t use these rare earth materials.

Electric Motor without Rare Earth Magnet

These motors are currently used for pumps and fans and aren't powerful to be used in electric vehicles. So, he started to work on finding a solution to the problem

Sansone started to find solution

Sansone worked hard over the course of the year and created a prototype of a unique synchronous reluctance motor

Sansone Success

Motor had greater rotational force or torque and efficiency than existing ones

Sanson Motor Efficiency

It took 15 tries to get the motor to its current state, something made easier with printed plastic, copper wires and a steel rotor

Total Tries to Make Motor 

His motor exhibited 39% greater torque to be exact and 31 percent greater efficiency at 300 revolutions per minute (RPM). At 750 RPM, it performed at 37 percent greater efficiency

Motor Performance

Robert Sansone won $75,000 for his innovative motor
