An electrodynamic machine shaft slow roll measurement testing and remediation method that can be performed on a partially machined shaft. Upon completion of slow roll tests on a partially machined shaft the manufacturer may complete machining of shafts that successfully meet the test specification. If a partially machined shaft fails the test specification, the manufacturer at its option may attempt to remediate the shaft, so that it successfully meets slow roll specification upon re-testing. Exemplary remediation steps may include further concentricity machining to reduce mechanical runout or shaft treatment, such as by heating and/or quenching to reduce electrical runout. Partially machined shafts that fail slow roll test specifications (with or without remediation efforts) may be scrapped or otherwise recycled without, completing final machining operations.
