High-temperature fans often employ several drives, with prominent ones including:

Direct drive is popular. This means the fan’s motor directly links to the impeller for airflow generation via motor rotation.

This design optimizes efficiency and energy consumption in high-temperature conditions, outperforming belt drive which typically ties the motor to the impeller via a belt.

Belt drive offers flexibility and shock absorption, yet it underperforms on efficiency and fits better for some colder or larger fans. So, for high-temperature fans, connecting motor to impeller through an axis device is a more frequent choice.
