| description | 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. on-linear torque in the form of an acceleration torque and/or a braking torque may be applied to either the rotor section or the stator section. Some embodiments include simulating downhole stall conditions via selectively engaging and disengaging a second motor and flywheel to vary rotational torque applied to the test coupon. Load performance of the test coupon may be evaluated over time in such simulated stall conditions. |
