Abstract:
A method for evaluating load performance of a rotor/stator test coupon, advantageously within a sealable test chamber comprising test fluid. In some embodiments, the test coupon comprises at least a partial length of a PDM stage, and in others the test coupon comprises a splined rotor/stator. The method includes rotating either the rotor section or the stator section, wherein such rotation actuates corresponding rotation of the other of the rotor section and the stator section. A braking torque is applied to the actuated one of the rotor section and the stator section such that load performance of the test coupon may be evaluated. Embodiments include selectively applying non-linear torque to load the test coupon, and evaluating load performance of the test coupon with reference to relative angular positions of the rotor section and the stator section over time.

Claim (Index 10):
The method of  claim 9 , in which the non-linear torque in step (b) is delivered by at least one technique selected from the group consisting of:\n (1) engaging an impact hammer-pin clutch when rotating the rotated first one of the rotor section and the stator section; (2) deploying a variable frequency drive motor to vary rotation speed of the rotated first one of the rotor section and the stator section; and (3) variably applying a braking torque to the actuated second one of the rotor section and the stator section.
