“…Various thermal management techniques exist for electric machines depending on their cooling needs [63]. Common cooling strategies include air-cooling (external and internal fans [64], [65]), liquid-cooling (direct cooling of windings or cooling jacket [66], [67]), oil-cooled systems [68], or some combination of these methods [69].…”

Accurate analysis of the thermal field in switched reluctance motor (SRM) is critical to the service life and safety performance of the SRM. According to the general structure of SRM, a twodimensional (2D) finite element analysis (FEA) model was established, and the loss of each component, especially the iron loss, was analyzed by Orthogonal Fourier decomposition method, revealing the characteristics of the loss. A magnetic-thermal one-way coupling method is further used to model the temperature of the SRM, and basic assumptions and reasonable boundary conditions are set. Transient thermal analysis was carried out under natural cooling conditions and high vacuum conditions, respectively, and the results were compared and analyzed to understand the temperature distribution of the main components under two operating conditions.

A bearingless switched reluctance motor (BSRM) has the same body structure as a switched reluctance motor (SRM), but the winding method is different. The accurate analysis of thermal characteristics is especially important for the service life and safety performance of the two motors. According to the initial design parameters, the initial size calculation equations of SRM and BSRM are given, and the ontology design parameters are obtained according to the same design goal. The two-dimensional finite element model is established, and the stator rotor iron loss is analyzed. The distribution characteristics of iron loss of SRM and BSRM are summarized. Secondly, the threetemperature field model of the motor is built, and the reasonable boundary conditions are set. The temperature distribution law of the two motors is analyzed. It is concluded that the BSRM components have lower loss and lower temperature rise under the same design target.
