Nominal Efficiency Values for Premium Efficiency Motors (Extracted from JIS C 4034-30:2011)

2026/02/03

The motors are fully enclosed with external fans; the 0.2 and 0.4 kW models are standard-efficiency motors. Models rated at 0.75 kW or higher are premium-efficiency motors (Top Runner motors).
The specifications for premium efficiency motors describe Top Runner motors that comply with JIS C 4213:2014, which corresponds to the efficiency classes (IE codes) defined in JIS C 4034-30:2011.
These values are for reference only. Frame numbers and rated values may vary depending on the motor manufacturer.
