1) ones of explosionproof type,
2) ones other than those satisfying all of the following conditions from a to g:
a. having a rated frequency or a base frequency of 50Hz±5%, 60Hz±5% or both 50Hz±5% and 60Hz±5% compatible,
b. operating in a single speed,
c. having a rated voltage of 1,000V or less,
d. having a rated output from 0.75kW or more up to 375 kW,
e. having either 2, 4, or 6 poles,
f. either whose duty type corresponds to S1 defined in JIS C 403430 (2011) or whose duty type corresponds to S3 with a duty hour rate of 80% or higher, and
g. driven by a commercial power supply.
3) ones integrated into a product (excluding models for export) which cannot be detached to measure energy consumption efficiency according to the method specified in Energy Conservation Law, Article 80, ltem 1, Section a,
4) ones whose thermal class corresponds to 180 (H), 200 (N), 220 (R) or 250 specified in JIS C 4003 (2010),
5) ones which have a deltastar starting system,
6) ones designed for vessels or ocean structures,
7) ones designed to operate wholly immersed in liquid,
8) ones of which difference between the synchronous speed and the rotational speed of the rotor meets the following:
a. 5% or more in a case where the output is 0.75 kW or more and 110 kW or less,
b. 3% or more in a case where the output is over 110 kW and 375 kW or less.
9) ones designed for gates of dam or weir,
10) ones whose stators and rotors are covered with metal materials,
11) ones designed for extremely low ambient air temperatures, specifically at temperature of less than 20 °C,
12) ones of external fan cooling types among inverterdriven models, or
13) ones manufactured for incorporation in products for exportation.
Energy Consumption Efficiency
A numeric value (%) obtained by dividing output (W) ^{*1} by input (W) using the numeric values measured by the method stipulated in JIS C 403421
*1: A value obtained by subtracting total loss from input. 
Categories & Target Standard Values
In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting energy consumption efficiency by shipment volume shall not be below the target standard value.
