Engine Cooling

The engine cooling fan is a high duty-cycle motor, essential in city traffic where the fan could be continuously on. ST provides leading ICs for the most reliable and cost-effective DC and brushless motor operation. ST’s brushless electronic components (here designed in a simplified block diagram) use the motor’s back EMF to detect rotor position, avoiding the need for expensive, high-temperature hall effect transistors.
