Abstract

This paper presents a design of novel 2-phase 4/3 SRM (Switched Reluctance Motor) with short flux path for an air-blower application. The desired air-blower is unidirectional application, and requires a wide positive torque region without torque dead-zone. In order to get a wide positive torque region without torque dead-zone during phase commutation, asymmetric inductance characteristic with non-uniform air-gap is considered. The proposed motor can be operated at any rotor position. The proposed 2-phase 4/3 SRM is verified by FEM (finite element method) analysis.
