2 SRM2-phase Switched Reluctance Motor with step stator structure

摘要

The present invention relates to a two-phase switched reluctance motor (SRM) of a stepped stator structure and, more specifically, to a two-phase SRM of a stepped stator structure, configured to prevent eccentricity of a rotor by changing a structure of a stator while resolving a torque dead zone. According to one embodiment of the present invention, the two-phase SRM of a stepped stator structure comprises: a stator surrounded by a wire including a plurality of stator poles; and a rotor accommodated in the stator and including a plurality of rotor poles facing an external side. A first pore, and a second pore, which is larger than the first fore, are formed on a surface of each stator pole by each rotor pole, and the first and second pores are configured to be connected to each other in a different radius. In addition, each of the stator poles protrudes towards one side so that the second pore is formed. Moreover, the stator has the eight stator poles, the rotor has the four rotor poles, and the SRM has two phases.
