Title:
STATORS FOR DOWNHOLE MOTORS, METHODS FOR FABRICATING THE SAME, AND DOWNHOLE MOTORS INCORPORATING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/058294
Kind Code:
A3
Abstract:
The present invention recites a method of fabricating a stator for a downhole motor, the method comprising the steps of providing a stator tube having an interior surface and applying a bonding agent to the interior surface of the stator tube. Additionally, a mandrel is positioned within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator. Furthermore, a reinforcing material is introduced into the stator tube to fill space between the mandrel and the interior surface of the stator tube and subsequently solidified to bond the reinforcing material to the interior surface of the stator tube, The mandrel is then removed from the bonded stator tube and reinforcing material such that a stator is fabricated.
