Canadian efficiency regulations are changing on June 28, 2017


Stricter efficiency requirements for AC asynchronous motors are coming into force in Canada from June 28, 2017. Motors in Canada that are newly launched onto the market, operated using the mains and in continuous operation will have to meet the requirements of the NEMA Premium / IE3 energy efficiency class from this date onward.

To provide you with comprehensive information on the future requirements, we've summarized the key changes below.

If you have any questions, please do not hesitate to contact us.

Which power ranges are affected?

The NEMA Premium / IE3 minimum efficiency class applies in Canada to motors in continuous operation in the following power ranges, depending on the number of poles, with effect from June 28, 2017:

  • 2 and 4 poles: Power range from 0.75 to 375 kW
  • 6 poles: Power range from 0.75 to 260 kW
  • 8 poles: Power range from 0.75 to 185 kW

Which exemptions remain? Which are eliminated?

The old regulations only applied to motors rated for a nominal frequency of 50/60 Hz or 60 Hz. From June 28, the regulations will also include motors that are rated for a nominal frequency of 50 Hz but can also be operated at 60 Hz.

The previous exemption for NEMA Design C / IEC Design H motors, flange motors and gearmotors also no longer applies. Or looking at this the other way around – once the new regulations come into effect, all flange motors with NEMA design A, B or C / IEC design N or H will have to achieve the IE3 energy efficiency class for the respective power range.

Comparison between exemptions in the old and new efficiency regulations:

EER 2010 exemptions valid till June 27, 2017

  • Motors that are not rated for a nominal frequency of 50/60 Hz or 60 Hz
  • Exempted are all drives that are not rated for continuous operation (S1)
  • Motors in line with NEMA design C (or IEC design H), flange motors and gearmotors only need to comply with the "Energy efficiency (~IE2)" efficiency class

EER 2016 exemptions valid from June 28, 2017

Exemption changed:

Motors that are not rated for a nominal frequency of 50 Hz, 50/60 Hz or 60 Hz

Exemption remains:

Exempted are all drives that are not rated for continuous operation (S1)

Exemption eliminated

The new regulations apply without limitation to motors manufactured from the day of the changeover to the stricter regulations and onward – i.e. on June 28, 2017 and later.

Which regulations apply to motors already delivered?

The following regulations apply to motors that have already been delivered to direct customers outside Canada and are now to be delivered to end customers in Canada:

  • Motor manufacturing date before June 1, 2016:
  • The current EER 2010 regulations still apply. They also apply if the motor is imported into Canada after June 28, 2017.
  • Motor manufacturing date in the period from June 1, 2017 inclusive to the period before June 28, 2017:
  • Transitional arrangements apply in this case.
  • If the date for importing the motor is before June 28, 2017, the old EER 2010 efficiency regulations still apply.
  • If the motor is imported on or after June 28, 2017, the new EER 2016 regulations apply to these products, provided the motor remains in the same Canadian province and is used there.

If the motor is imported before June 28, 2017 but is not subsequently transported to another province in Canada till on or after June 28, 2017, the new EER 2016 regulations also apply.

Is it still permitted to repair motors in the field and then take them back into operation?

  • Motors that are taken into operation before the deadline of June 28, 2017 but no longer meet the new efficiency requirements may be repaired.
  • However, no replacement drive in the same configuration may be taken into operation if it no longer meets the applicable legal requirements.

In practice, this means that once a drive is defective, the service department or service partner locally may repair it using appropriate spare parts. However, placing a technically identical drive onto the market as a replacement is not permitted.

Don't want to spend long thinking about this? Prefer to order a motor that meets the new efficiency requirements right away?
