Determination of small electric motor efficiency.

CFR · 2024-01-01 · US · Title 10

(a) (b) (2) (i) Derived from a mathematical model that represents the mechanical and electrical characteristics of that basic model, and (ii) Based on engineering or statistical analysis, computer simulation or modeling, or other analytic evaluation of performance data. (3) (i) The AEDM must be applied to at least five basic models that have been tested in accordance with § 431.444; and (ii) The predicted total power loss for each such basic model, calculated by applying the AEDM, must be within plus or minus 10 percent of the mean total power loss determined from the testing of that basic model. (4) (ii) If requested by the Department, the manufacturer shall conduct simulations to predict the performance of particular basic models of small electric motors specified by the Department, analyses of previous simulations conducted by the manufacturer, sample testing of basic models selected by the Department, or a combination of the foregoing. (5) (ii) For each basic model for which a certification program is not used as described in paragraph (b)(5)(i) of this section, any testing of a motor to determine its energy efficiency must be carried out in accordance with paragraph (c) of this section. (c) (A) Two of the basic models must be among the five basic models that have the highest unit volumes of production by the manufacturer in the prior year, or during the prior 12 calendar month period beginning in 2015, whichever is later, and comply with the standards set forth in § 431.
