Axial flux switched reluctance (AFSR) motors combine the characteristics of switched reluctance motors and axial flux motors. It has several advantages
including a simple structure
low manufacturing and maintenance costs
short axial length
adjustable air gap
and strong adaptability to harsh environments
such as high temperatures. These advantages make AFSR motors suitable for high-reliability and fault-tolerant applications in industries like aerospace
new energy vehicles
and intelligent manufacturing. In recent years
AFSR motors have attracted growing attention. This paper reviews the latest research in the field of AFSR motors
introducing their basic principles and four key topological structures: single-stator-single-rotor
single-stator-double-rotor
double-stator-single-rotor
and multi-stator-multi-rotor. This paper also discusses advancements in AFSR motor design
focusing on electromagnetic design calculation methods
algorithm acceleration
core materials
manufacturing processes
and optimization of electromagnetic properties. Based on the unique features of AFSR motor topological structures
this paper summarizes current research on loss analysis and suppression
temperature rise and heat dissipation
torque ripple analysis and suppression
and motor fault and structural strength analysis. Furthermore
this paper introduces control systems for AFSR motors and highlights innovations in control strategies developed by researchers worldwide. Finally
it presents applications of AFSR motors in electric vehicles
wind power generation
and industrial equipment
and provides an outlook on future research directions and development trends. The review work in this paper provides valuable references for both theoretical research and practical engineering applications of AFSR motors.
