In automobile, the introduction of electronically commutated motors has been accompanied by a proliferation of electronic devices. With this proliferation of electronic devices, an emphasis has been placed on EMC issues. This paper is proposed to use SRM as a radiator cooling fan in automotive applications. To drive SRM, Energy efficient C-dump converter is applied. It is verified more efficient than other converters through simulation and experiments. And also SRM is valid automotive applications that have strict EMC standards. It is compared SRM with BLDC and DC motor by experiments.

The major trend in global automotive market is changing drastically in the way that a vehicle FECPS(Front End Cooling Pack System) is designed and manufactured as an assembly part. The system can encompass many functions, be assembled into a vehicle as a module, and reduce the production cost as well as time. The FECPS consists of an impact beam, an aluminum condenser and a radiator, a carrier and a cooling fan with a BLDC motor. In order to predict the performance of a FECPS accurately, it is essential to properly model the air flow field through various heat exchangers, such as a condenser or a radiator. In this study, the flow field of the system is measured by a PIV(Particle Image Velocimetry) system. The result is compared with that measured with multi-channel anemometer.
