Motor Controls are systems that manage how industrial motors start, stop, and run. Think of them as the 'brains' that control machines in factories, production lines, and industrial equipment. They help keep machines running safely and efficiently, kind of like a sophisticated light switch system but for industrial equipment. These systems can be either traditional electrical switches and buttons (called electrical controls) or modern computer-based systems (called electronic controls). When someone mentions motor controls in their resume, they're talking about their ability to work with these systems that make industrial motors work properly.
