Cooling fans are an important device needed in consumer electronic products. To enhance the performance of cooling fans, this paper presents a novel brushless dc motor with a three dimensional stator structure using soft magnetic composite to reduce the hub size and allow more airflow. Four models are designed and their output characteristics are compared using finite element simulation. From the results, one of them is selected for prototyping whose performance appears to meet the requirement. The prototype has a 10% smaller diameter than that of conventional types. Moreover, the operation test shows that the required performance is achieved.
