LARGE TORQUE】 The stable pure purple copper ... HIGH EFFICIENCY & EFFICIENT HEAT DISSIPATION】 The speed of a 120W motor can reach 45rpm, ensuring high efficiency and saving you a lot of ...

Like other PCB motors it produces very little torque, roughly 2% of a typical NEMA17 stepper motor. Even so, the engineering behind this project remains impressive.

Robert Sansone is the winner of the 2022 Regeneron International Science and Engineering Fair for his research on high-torque, magnet-free electric motors. The innovative design could make EVs ...
