On September 28, 2018, Energy Conservation (Regulated Goods and Registered Suppliers) (Amendment) Regulations 2018 (hereinafter referred to as the Regulations) were promulgated in Singapore. It comes into operation on October 1, 2018. The Regulations amend certain provisions of Energy Conservation (Regulated Goods and Registered Suppliers) Regulations 2017, and newly bring a “single speed, three-phase squirrel cage induction motor” under the regulation of minimum energy efficiency standards. The newly regulated motor must be registered, satisfy the applicable minimum energy efficiency standards, and comply with the obligation to display product information. The detailed definition of a regulated motor is specified separately in the order described below.
The minimum energy efficiency standards for motors specified by the Regulations are as follows.
Minimum energy efficiency standards
|Motors with rated output of or exceeding 0.75 kW and below 200 kW||Nominal efficiency (ηN) at rated output ≥ minimum nominal efficiency|
|Motors with rated output of or exceeding 200 kW and not exceeding 375 kW||(a) for 2-pole motors: ηN at rated output ≥ 95.8
(b) for 4-pole motors: ηN at rated output ≥ 96
(c) for 6-pole motors: ηN at rated output ≥ 95.8
The following three pieces of product information are to be displayed. The information must be clearly displayed on the nameplate of the motor.
- Year of manufacture
- International Energy Efficiency class as specified in the test report
- Nominal efficiency at rated output

The definition of regulated motors:
Along with the Regulations, Energy Conservation (Prescribed Regulated Goods) (Amendment) Order 2018 (hereinafter referred to as the Order), which provides for the definition of regulated motors, was also promulgated on the same day (September 28, 2018). It comes into operation on October 1, 2018.
A motor to be regulated is a single speed, three-phase 50 Hz or 50/60 Hz, squirrel cage induction motor with all of the following characteristics. Note that motors that are designated to be exempted from application are excluded.
- A motor that has 2,4, or 6 poles
- A motor that has a rated voltage of up to 1,000 V
- A motor that has a rated output between 0.75 kW and 375 kW
- A motor that is rated for duty type S1, S3 (with cyclic duration factor of 80% or more), S6 or S9, in accordance with IEC 60034-1 (2017)
