For Suppliers

On this page, find out about the minimum energy performance standards (MEPS) that apply to some motor types, the regulatory requirements for electric motors and FAQs.

Overview

Electric motors are used in a wide range of applications, from large industrial equipment such as in mining operations, down to small household appliances like hair dryers.

The majority of electric motors draw less than 0.75 kW of power and are used in the residential and commercial sectors, for example inside refrigerators and computer hard drives. They account for only a small proportion of all electric motor power consumption.

The largest proportion of motor electricity consumption is attributable to mid-size motors with output power of 0.75 – 375 kW. These motors are predominantly used in industrial applications such as to power pumps, compressors and fans.

Regulatory requirements for electric motors

Three phase electric motors are subject to Minimum Energy Performance Standards (MEPS) requirements in Australia and New Zealand.

What electric motors are covered?

Minimum energy performance standards (MEPS) ensure that a minimum level of energy efficiency is achieved for three phase cage induction motors with output power from 0.73 kW up to, but not including, 185 kW, with rated voltages up to 1100 V, alternating current (AC).

The Minimum Energy Performance Standards requirements are set out as minimum efficiency levels.

Efficiency Levels are set out in the tables below.

FAQ for Suppliers

What Determination do I need to register my motor to?

You can register your motor to the current 2012 Determination or the new 2018 replacement Determination, which was published on 14 November 2018 and will come into force on 14 May 2019.

You can register your motor under either Determination until 14 May 2019. On this date, the replacement 2018 Determination will come into force and suppliers will only be allowed to register to the 2018 Determination.

To avoid any potential future inconvenience, suppliers may now wish to register motors in accordance with the provisions of the 2018 Determination and provide a test report to the IEC 60034-2-1 test standard.  This will ensure that any new registrations will not be affected when the 2018 Determination comes into force.

Further details concerning the differences between the two Determinations can be found here or in the FAQ section below. You can also watch our YouTube video for more details.

Which motors need to be registered for MEPS?

All three phase cage induction motors that fall under the scope of either the current 2012 Determination or the replacement 2018 Determination  must be registered before they can be legally sold in Australia.

Information about the regulatory requirements and registration is available here.

Further information is available in the Standard AS/NZS 1359.5-2004.

Does MEPS apply to single-phase motors?

In regards to mandatory minimum energy performance standards (MEPS), there are no regulations currently in place for single phase motors. However, there may be other state or federal laws (for example, electrical safety laws) that may apply to single phase motors.

You may wish to contact the electrical safety department in your state or territory for further information.

Does MEPS apply if the electric motor is part of new packaged equipment?

Generally, three phase cage induction motors that are incorporated into machines need to meet Australia’s and New Zealand’s regulatory requirements and must be registered before they can be offered for supply.

However, the 2012 Determination states that ‘…motors that are integral to, and not separable from, a driven unit’ are exempt from registration. For example, a motor constructed on the same shaft as a compressor for an air-conditioning unit may not be required to be registered.

The 2018 Determination  provides clarification concerning this provision and notes that for this exclusion to apply, motors in machines ‘…cannot operate as a motor if separated from the driven unit, even if a temporary end shield or a drive end bearing is fitted’.

2012 Determination - In the MEPS standard for motors (AS/NZS 1359.5:2004) which of the efficiency tables are mandatory and which are optional?

In AS/NZS 1359.5:2004, the mandatory MEPS requirements are set out as minimum efficiency levels. These mandatory levels came into effect in Australia from 1 April 2006 and are set out in the tables below as well as in AS/NZS 1359.5:2004. If Test Method A (AS/NZS 1359.102.3) is used, then Table A2 applies. If Test Method B (AS 1359.102.1) is used, then Table B2 applies. AS/NZS 1359.5:2004 also specifies voluntary high efficiency levels – Table A3 (for Test Method A) and Table B3 (for Test Method B).

2012 Determination - How do the IEC 60034-30 efficiency classes relate to Australian/New Zealand MEPS levels for motors?

Once the 2018 Determination comes into force, Australian/New Zealand MEPS levels will be aligned with IE2 levels. In the interim period, suppliers can register under either the 2012 Determination or the 2018 Determination. If registering under the 2012 Determination for IE2 efficiency class motors (from IEC 60034-30) depending on the size of the motor, there are some differences between the IE2 levels in IEC 60034-30 and the Australian/New Zealand MEPS levels specified in the Standard AS/NZS 1359.5-2004. In particular, IE2 levels are lower than the 2012 Determination levels for the smaller 2 and 4 pole motors. Also, IEC 60034-30 does not cover 8 pole motors. All motor suppliers must ensure that any motors registered and sold in Australia comply with the current Australian/New Zealand MEPS levels.

2012 Determination - Can I register my motors based on the IEC 60034-2-1:2007 test method standard?

The IEC 60034-2-1:2007 test method standard currently lists 10 different test methods, including equivalent (but not identical) test methods to our Method A and Method B. Companies can choose a test method for registration, including IEC 60034-2-1, but they will need to specify whether it is Method A or Method B equivalent in their registration. However, it is the responsibility of companies to ensure that their motors will meet our MEPS levels. All check testing undertaken by the E3 Program will be done to Method A or Method B (whichever has been specified in the registration).

2012 Determination - Why are there two different test methods for the motor efficiency levels and what is the difference between them?

The AS/NZS standard 1359.5:2004 describes two internationally recognised test methods for motor efficiency levels. Both are valid for MEPS and are referred to as Test Method A and Test Method B. The main difference between the two test methods is in the way stray load losses are accounted for.

The following is an extract from AS/NZS: 1359.5:2004: Method A:

This method is identical to Method 1 of IEC 61972. It is also technically equivalent to the method specified in IEEE 112-B (USA). This method requires direct measurement of additional load losses and differs from Method B described below. Method B: This method is drawn from AS 1358:102.1, which is based on IEC 60034-2, including Amendment 1:1995 and Amendment 2:1996. In this method, an allowance of 0.5% fixed stray (additional load) loss is assumed for all the motors.

NOTE: The standards referred to in the current 2012 GEMS Determination are a ‘snapshot in time’; the information provided in the paragraph above is reflective of these standards at a given point in time. However, feedback provided by industry has highlighted the significant confusion this causes for applicants. In order to reduce this confusion, the GEMS Regulator advises that applicants may now nominate Test Method A when registering electric motors tested under IEC 60034-2-1. This is an interim arrangement until the 2018 Determination comes into force.

2018 Determination - What changes does the replacement 2018 Determination introduce?

The replacement 2018 Determination introduces the following changes:

  • Clarification to the product class that requirements apply only to 2, 4, 6 or 8 pole motors;
  • A single test method – Method 2-1-1B – and a single test standard: IEC 60034-2-1;
  • Inclusion of energy performance requirements within the 2018 Determination itself;
  • Alignment of MEPS with IE2 levels;
  • Alignment of high efficiency levels with IE3 levels;
  • A family of models for electric motors.
2018 Determination - What is a family of models?

A family of models refers to several models from the same product class that all share particular characteristics as defined by the product’s Determination. This allows the models to be registered under a single registration in the registration system.

The 2018 Determination introduced a family of models arrangement for electric motors.

To qualify for this arrangement, each model must:

  • Have the same brand
  • Have the same frame size or frame code
  • Have the same number of poles
  • Have the same duty type
  • Have the same rated output power; and
  • Rely on a single test report.
2018 Determination - Can a fee concession be used with the replacement 2018 Determination?

No. The fee concession that is in place for the current 2012 Determination is replaced by the new family of models arrangement. The fee concession arrangement will remain in place for motors registered under the current 2012 Determination until the replacement 2018 Determination comes into force.

2018 Determination - What happens to motors already registered under the current 2012 Determination?

When the 2018 Determination comes into force, all motors registered under the 2012 Determination will be revalidated against the requirements of the 2018 Determination to ensure compliance with the new MEPS levels. If any 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.

Efficiency Level Tables

The following efficiency levels apply to the current 2012 Determination.
