Brushless Cooling Fan System

Last update: 29 Aug. 2023

What is a Brushless Cooling Fan System?

As part of the engine cooling system, fan systems include a fan system motor, a blade and a shroud.

Electrification and new ICE require greater fan system power and therefore higher energy consumption that generate higher noise levels.

Blade and shroud design have been improved to optimize acoustics and efficiency whilst light and compact brushless motors provide maximum airflow at minimized noise levels for powertrain/battery cooling, with best-in-class efficiency.
