Using 3-D printed plastic, copper wires, and a steel rotor, the teen designed a new sort of prototype synchronous reluctance motor. These motors typically power smaller items like fans, as they lack the torque and power to move larger objects such as EVs. While a traditional EV motor uses electromagnetic fields to spin the motor, a synchronous reluctance motor uses a steel rotor with air gaps within a rotating magnetic field. The reluctance—or magnetism—of the steel rotor generates torque.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
