ABSTRACT:
The rotor of a downhole motor includes a mandrel having at least one radial lobe, and an elastomeric tubular sleeve compressed about the mandrel so as to establish frictional engagement therebetween. The sleeve is compressed about the mandrel through one of various processes, including heat shrinking, vacuum shrinking, and stretching.
