Abstract

The electrical power demand in automobiles is increasing steadily every year due to addition of new electrical systems that enhances passenger comfort and safety. The present in vehicle 14 V DC power system is being pushed to the maximum limits to meet the high power loads. In the mean time, the 42 V power network("PowerNet") in future automobiles enables a number of new features that require high power loads including electric power steering, engine cooling Fan system, electric compressors etc. This paper presents a design and implementation of brushless DC (BLDC) motor and controller for engine cooling fan system for 42 V Automotive applications. Experimental results from a laboratory prototype are presented to validate the feasibility of the proposed BLDC motor and drive.
