Abstract
A stator/rotor assembly includes at least one extruded preform bonded to a stator housing and/or a rotor mandrel. A method of constructing a stator/rotor assembly includes extruding at least one preform, and bonding the preform to a stator housing and/or a rotor mandrel. A method of constructing a stator includes applying multiple polymer strips to a bladder; and bonding the polymer strips to a stator housing while compressing the polymer strips between the bladder and the stator housing, without injection molding. A method of constructing a rotor includes applying multiple polymer strips to a rotor mandrel, and bonding the polymer strips to the rotor mandrel while compressing the polymer strips between a bladder and the rotor mandrel, without injection molding.
