and motors are game-changers in power systems. They use special materials that conduct electricity without resistance, making them super efficient and powerful. This means we can make machines that are smaller, lighter, and pack a bigger punch than regular ones.
These cool machines have some awesome perks. They're more stable, can handle bigger power loads, and work great even when they're not running at full steam. But there are some challenges too, like keeping them super cold and dealing with the high costs of making them.
