Claim 11:
12. A method of using a downhole motor comprising a stator and a rotor, the method comprising:
disposing a cartridge having at least one lobe of the rotor over a core to form the rotor;
disposing the rotor within a cavity defined by the stator, the stator having at least one lobe and having a first end disposed closer to a first end of the rotor than to a second end of the rotor longitudinally opposite the first end of the rotor and a second end of the stator longitudinally opposite the first end of the stator disposed closer to the second end of the rotor than to the first end of the rotor;
passing a fluid through the cavity defined by the stator to rotate the rotor;
removing the rotor from the cavity defined by the stator after passing the fluid through the cavity;
reversing a longitudinal direction of the rotor, wherein reversing the longitudinal direction of the rotor comprises:
removing the cartridge from the core;
reversing a longitudinal direction of the cartridge; and
disposing the reversed cartridge over the core; and

re-disposing the rotor into the cavity defined by the stator such that a first end of the cartridge is closer to the second end of the stator than to the first end of the stator and a second end of the cartridge is closer to the first end of the stator than to the second end of the stator.
