Comparative analysis of SRMs for automotive cooling fan application

This paper presents a comparative analysis of 6/4, 12/8 and 8/6 switched reluctance motors(SRM) for automotive cooling fan. Three-types of 600[W] SRM are designed and compared. An approximate sizing of proposed motors are obtainable using a power output equation. And selection of machine variables are selected to meet the requirements of the application. Described parameters are achieved through an iterative process of steady-state performance calculation. The characteristic of the proposed motors are compared through torque, inductance, and efficiency. Finite Element Analysis (FEA) transient analysis are used to analyze the characteristic of the proposed motors.
