ABSTRACT
In a switched reluctance motor, electromagnetic forces create the motion. Similar to other types of electric machines, the operational principles of an Switched Reluctance Machine can be explained with the laws of electricity and magnetism. The similar magnetic field configuration can be created with an electromagnet, where the magnetic field is produced by an electric current. The electromagnet was created by winding the current carrying conductor around an iron core. Iron is a ferromagnetic material. Due to their magnetic properties, when exposed to an external field, the magnetic field inside a ferromagnetic material is different when compared to the field outside of the material. When the rotor pole approaches the vicinity of the stator pole, the change in the magnetic field configuration is due to the change in the reluctance of the magnetic path. It should be noted that the increase in the external field does not create an indefinite increase in the magnetic flux density.
