Scope
1.1
This Standard specifies the test methods to be used in measuring the energy efficiency of small single- and three-phase rotating motors. This Standard includes but is not limited to the following motor types:
(a) capacitor (permanent-split);
(b) capacitor (capacitor-start, capacitor-run);
(c) capacitor-start;
(d) split-phase;
(e) split-phase-start, capacitor-run;
(f) shaded-pole;
(g) repulsion;
(h) repulsion-induction;
(i) repulsion-start-induction-run;
(j) reluctance;
(k) universal*;
(l) dc¹;
(m) permanent magnet¹;
(n) brushless dc¹;
(o) inverter driven motors¹;
(p) polyphase induction motors.
The method of quoting and the permissible tolerance on the nominal efficiency values are also specified.
*The tests listed apply to operation on alternating current only.
¹These motors also include an integral converter that operates on alternating current.
1.2
This Standard applies to three-phase motors rated up to 0.746 kW at 1800 r/min (or equivalent*) and single-phase motors rated up to 7.5 kW.
*An equivalent motor is a motor with the same torque output but with different kilowatt output and speed. Torque varies as kilowatts per revolutions per minute.
