An Axial-Flux Motor for an Electrified World: It Combines the Best of Two Motor Designs to Save Weight and Energy

Although the idea of replacing a hunk of iron with a light-weight, ultrathin, easy-to-make, long-lasting PCB was attractive from the outset, it didn't gain widespread adoption in its earliest applications inside lawn equipment and wind turbines a little more than a decade ago. Now, though, the PCB stator is getting a new lease on life. You can expect it to save weight and thus energy in just about everything that uses electricity to impart motive force.
