Energy Minimum Standards for Electric Motors Come into Force in Australia
On November 14, 2018, the replacement of the Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2018 was published.
As mentioned in the document, starting from May 14, 2019, suppliers must register motors in accordance with the new Determination.
The Determination 2018 establishes minimum energy efficiency requirements and associated requirements for conducting tests for three-phase cage induction motors with:
rated output power greater than or equal to 0.73 kW but less than 185 kW
rated voltage of up to 1100 V of alternating current
2, 4, 6 or 8 poles
This class of products forms a single product class for the purposes of the Act.
The principal change in the new Determination relates to the specified test method. The current requirement still allows suppliers to test motors to IEC 60034‑2‑1 Ed 2.0 test standard. However, the options for suppliers to test motors using other methods including either Method A or Method B specified in the Determination 2012 have been removed.
Other changes include:
1. Provision of a ‘family of models’ facility that enables up to 10 models to be included within a single family registration. To be qualified, each model in the family must:
a) be of the same brand
b) have the same frame size
c) have the same characteristics for each of the following: number of poles, duty type, and rated output power
d) rely on a single test report that was prepared prior to the application for registration
2. There are some relatively small changes to the minimum energy performance standards (MEPS) levels applicable in Australia as well as the high-efficiency levels. This will align Australia’s MEPS levels with IE2 levels and high-efficiency levels with IE3 levels. The Determination 2018 contains tables specifying MEPS and high-efficiency levels.
3. A new test procedure for totally enclosed air over motors has been included.
4. Efficiency tables for 60 Hz motors have been included. These motors are covered by the Determination 2012 but are currently being assessed against 50 Hz efficiency levels.
From May 14, 2019, all motors registered under the Determination 2012 will be revalidated against the requirements of the new Determination to ensure compliance with the new MEPS levels. If any of the registered models fail to meet the new MEPS levels, their registration status will become ‘superseded’. Consequently, no further imports of these models can occur but Australian stock can be supplied until it is exhausted.
