Abstract
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 three-temperature 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.
