The field of electric motors has recently entered a new era. The electric motors that you see today in everything from washing machines, toys, and fans use the same basic principles as motors from 50 years ago. But with the realization of using superconducting wire to replace conventional copper coils, motors are becoming more compact, more energy efficient, and less expensive, which will have advantages particularly for large industrial applications.
