What is a family of models for electric motors?

In November 2018, the Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2018 introduced a new family of models arrangement for three phase cage induction motors.

This family of models arrangement replaces the previous fee concession arrangement. The fee concession was an interim arrangement that allowed registrants to register up to 10 models for one fee, provided that the models shared the same frame code and brand.

The family of models arrangement continues under the Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2019 , which commenced on 10 July 2019.

To be eligible for a family of models registration, the following characteristics must be the same for each model in the family:

  • brand
  • frame size
  • number of poles
  • duty type
  • rated output power (in kilowatts); and
  • rely on a single test report that was completed prior to the application for registration being prepared.

For each model in the family, the product of the rated voltage and the rated current (i.e. voltage x current) must be the same.

There also can be no more than 10 models in one family.

The fee for a family registration is the same as a single registration, which is $670. Suppliers can minimise registration costs by using the family of models facility where applicable.

The GEMS Regulator recognises that the family of models arrangement is a significant change from the previous fee concession arrangement, and has received feedback from some registrants about the new arrangement.

The GEMS Regulator is working with these registrants to transfer existing single model registrations into family of models registrations where appropriate. The Regulator is also investigating how the process may be simplified.
