What is a notable advantage of AC motors when compared to DC motors?

AC motors are notable for several advantages, one of which is that they do not use brushes. This characteristic leads to several benefits. The absence of brushes eliminates brush wear, which means less maintenance is required over the motor's lifespan. Additionally, the lack of brushes reduces friction, which can enhance the motor's longevity and reliability. This design feature also results in less electrical arcing, contributing to increased operational safety and reduced electromagnetic interference.

While there are other advantages associated with different types of motors, the elimination of brushes is a fundamental attribute of AC motors that typically sets them apart from DC motors. This attribute not only simplifies maintenance but also enhances the operational efficiency and reliability of AC motors in various applications, including elevator systems. The other options, while they may have merit in specific contexts, do not capture this unique and significant advantage.
