Abstract

This article presents a novel memory motor drive with integrated winding concept for traction applications. The key feature of the proposed idea is to integrate the excitation winding with armature winding, and hence eliminating additional magnetization winding to achieve online magnetization-state regulations. Hence, the spatial confliction of conventional memory motors can be solved. Upon implantation of the proposed design, the winding utilization, torque/power density and fault tolerant capability are significantly improved. Based on the field modulation theory, the air-gap flux densities under different magnetization states are derived quantitatively to provide design guideline in initial stage. The integrated memory motor drive is presented systematically to consolidate the field and armature windings. To illustrate the effectiveness of the proposed design, two other conventional memory motors are included for comparisons. It is revealed the presented memory motor with integrated winding concept exhibits 28% higher winding utilization, 43% higher torque/power density and 218% higher flux regulation capability than its counterpart with conventional separate windings. In addition, fault tolerant capability can be significantly improved by eliminating mutual coupling between two winding sets. Finally, a prototype is fabricated, and the experimental measurements are carried out to verify the presented concepts.
