His new prototype had 39 percent greater torque over a traditional motor.
A young engineer called Robert Sansone won the first prize, and winnings of $75,000, at this year's Regeneron International Science and Engineering Fair , the world's largest international high school STEM competition., his new invention could one day transform the electric vehicle industry. It is a synchronous reluctance motor with improved performance over previous models.Typically these types of motors are used for pumps and fans, but they aren't powerful enough for EVs.
The high-schooler set out to improve on existing models of the synchronous reluctance motor, as it doesn't require rare-earth metals. Over the course of a year, he created a prototype for a new type of synchronous reluctance motor that has greater torque and efficiency than existing models. The prototype was made of 3D-printed plastic, copper wires, and a steel rotor.
