Abstract
The present invention recites a downhole motor and method of fabricating the same, wherein the method for fabricating a stator for a downhole motor includes the providing of a mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator and the application of a flexible sleeve over the mandrel. Additionally, a stator tube having an interior surface is provided and a bonding agent is applied to the interior surface of the stator tube. The flexible sleeve and the mandrel are placed in the stator tube and a reinforcing material is introduced into the stator tube to fill space between the flexible sleeve and the stator tube. The reinforcing material is solidified and serves to bond the reinforcing material to the flexible sleeve and the stator tube.
