Federal Register / Vol. 86, No. 1 / Monday, January 4, 2021 / Rules and Regulations method when brought to market. First, DOE reviewed the product catalogs of four major small electric motor manufacturers published over a sevenyear period.29 DOE compared the current product offerings to the historical catalogs to identify the total number of new models listed over that period of time.30 DOE then annualized that total number of new models.31
Next, DOE scaled up that annualized value based on the estimated market share of the manufacturers whose catalogs were reviewed. This scaled-up annualized value estimated the total number of new models listed for sale each year for the entire U.S. market.32
Then, DOE estimated that 10 percent of new models would be tested each year.33 DOE made this estimate based on 1 knowledge that many motor models are grouped under a single basic model classification and therefore each individual model would not need to be tested, 2 observations that only a fraction of electric motor basic models are tested the remainder have efficiency determined through an alternative efficiency determination method AEDM, and 3 recognition that many motor models may have been relabeled or rebranded but not redesigned and therefore no new testing is needed. Finally, DOE
assumed that 10 percent of small electric motor models sold in the U.S.
that are tested with either the CSA or IEEE methods referenced in the Federal test procedure are also tested with the IEC 6003421 method. Based on these calculations, DOE determined that approximately 1 new small electric motor basic model per year i.e., 10
percent of 13 that already would be tested with the IEC 6003421 method would no longer have to conduct an additional test to comply with DOEs amended test procedure when introduced into the U.S market and therefore would realize costs savings 29 The seven-year period for which DOE reviewed product catalogs was from 2009 to 2016. DOE
expects this approach will also be representative of the market from 2016 to the present. DOE did not receive comment on this approach following the publication of the April 2019 NOPR.
30 DOE identified 598 small electric motor models introduced into the U.S. market by these four manufacturers during the period 20092016.
31 Based on this count, DOE estimates that these four small electric motor manufacturers collectively introduced approximately 85 small electric motor models into the U.S. market each year.
32 This scaled-up calculation yielded a value of 128 small electric motor models introduced each year for the entire U.S. market, as DOE assumed these four small electric motor manufacturers represented approximately 67 percent of the entire U.S. market.
33 DOE estimates that approximately 13 new small electric motor models are tested each year.

due to the test procedure amendments.34
DOE estimated the cost of testing a single small electric motor unit to be $2,000 at a third-party facility and approximately $500 at an in-house facility.35 DOE requires at least five units to be tested per basic model. 10
CFR 431.445c2 To estimate in-house testing costs, DOE assumed testing a single motor unit requires approximately nine hours of a mechanical engineer technician time and three hours from a mechanical engineer. The mean hourly wage for a mechanical engineer technician is $28.00 and the total hourly compensation paid by the employer including all fringe benefits is $36.25.36 The mean hourly wage for a mechanical engineer is $44.62 and the total hourly compensation paid by the employer including all fringe benefits is $57.76.37 In addition, DOE assumed that 50 percent of tests are conducted at third-party facilities and 50 percent of tests are conducted at in-house facilities. Based on these estimates, DOE
anticipates annual cost savings of approximately $8,000 for the small electric motors industry.
2. Cost Impacts for Electric Motors Regarding electric motors, DOE is not amending the scope of applicability of the test procedure at Appendix B.
Consistent with the small electric motors analysis, the incorporation of IEC 6003421:2014 in this test procedure provides manufacturers additional flexibility by permitting an alternative and equivalent test procedure for measuring energy loss and would further harmonize DOEs test procedures with current industry practice and international standards.
34 This yields an estimate of 1.28, since DOE
estimates 10 percent of the 12.8 new small electric motor models introduced each year are already tested with the IEC 6003421 method.
35 Estimate based on standard rates charged by third party laboratories.

DOE expects that, for those manufacturers who are already using IEC 6003421:2014, this change will reduce the number of tests that manufacturers perform by avoiding the need to conduct a test according to the CSA or IEEE methods 38 currently referenced in DOEs test procedure.
To calculate the testing cost reduction associated with allowing the IEC 60034
21:2014 method for testing electric motors, DOE employed a similar methodology to the small electric motors analysis and estimated the number of electric motor models that would not have to test to both the amended DOE test procedure and the IEC test method when brought to market. First, DOE reviewed the product catalogs of four major electric motor manufacturers published over a six-year period.39 DOE compared the current product offerings to the historical catalogs to identify the total number of new models listed over that period of time.40 DOE then annualized that total number of new models.41
Next, DOE scaled up that annualized value based on the estimated market share of the manufacturers whose catalogs were reviewed. This scaled-up annualized value estimated the total number of new models listed for sale each year for the entire U.S. market.42
Then, DOE estimated that only 10
percent of new models would be tested each year.43 DOE made this estimate based on 1 knowledge that many motor models are grouped under a single basic model classification and therefore each individual model would not need to be tested, 2 observations that only a fraction of electric motor basic models are tested the remainder have efficiency determined through an AEDM, and 3 recognition that many motor models that may have been relabeled or rebranded but not redesigned and therefore no new 38 CSA 39010 or IEEE 1122017 per the amended reference under this final rule depending on the category of electric motor.
39 The six-year period for which DOE reviewed product catalogs was from 2010 to 2016. DOE
expects this approach will also be representative of the market from 2016 to the present. DOE did not receive comment on this approach following the publication of the April 2019 NOPR.
40 DOE identified 8,110 electric motor models introduced into the U.S. market by these four manufacturers during the period 20102016.
41 Based on this count, DOE estimates that these four electric motor manufacturers collectively introduced approximately 1,352 electric motor models into the U.S. market each year.
42 This scaled-up calculation yielded a value of 2,028 electric motor models introduced each year for the entire U.S. market, as DOE assumed these four electric motor manufacturers represented approximately 67 percent of the entire U.S. market.
43 DOE estimates that approximately 203 new electric motor models are tested each year.
