<p>The purpose of the present invention is to provide a rotor for a switching reluctance motor capable of reducing torque ripple by smoothening with mechanical kinetic energy and accumulating toque though a flywheel. The present invention includes: a magnetic separation polarity structure capable of minimizing the magnetic-mechanical switching vibration sound noise of the switching reluctance motor and improve toque generation performance. For this, the switching reluctance motor includes a rotor body part of ring shape; a rotor polarity which is formed with a constant distance in the rotor body part; and opening holes which is formed with a constant distance on the rotor polarity. The rotor polarity includes a rotor convex polarity which protrudes with a constant distance from the inside of the rotor body part in a radial direction and has a step difference in a center part. a rotor concaved polarity which is formed in the outside of the rotor body part in the redial direction. Therefore, a positive toque generation area due to the switching alternation of an armature can generate high toque in a large band type outer rotor. Thereby, power density from low level to high level can be secured according to the rotor toque.</p> |
