Patent ID: 7687949

Claim:
A rotor of a synchronous reluctance motor, comprising: a laminated core, comprising: a plurality of stacked silicon steel sheets, wherein each of the plurality of silicon steel sheets is equally divided into a plurality of regions with respect to a center of each of the plurality of silicon steel sheets such that the laminated core is also divided into the plurality of regions; a plurality of barriers including first, second and third holes formed within each of the plurality of regions; and guide pin holes formed between adjacent regions of each of the plurality of silicon steel plates; end plates fixed to opposite ends of the laminated core; guide pins that extend through each of the guide pin holes and having each of two opposite ends thereof coupled to a respective end plate so as to align the plurality of stacked silicon steel sheets; and at least one rivet that couples the laminated core and the end plates, wherein the at least one rivet extends through a receiving portion of the second hole formed in a corresponding one of the plurality of regions in each of the plurality of silicon steel sheets, and wherein the at least one rivet is supported within the receiving portion of the second hole by a rivet support unit, wherein the rivet support unit comprises a first protrusion that extends from a first inner peripheral surface of the second hole toward a central portion of the second hole and a second protrusion that extends from a second inner peripheral surface of the second opposite the first inner peripheral surface toward the central portion of the second hole so as to support a body portion of the at least one rivet therebetween.
