Energy efficiency standards from electric motors

Are you aware of the changes in the IE regulations for electric motors, coming into force July?

Ok, so this post is a little more mundane than our usual ones, but if this affects you, bear with us!

These changes are coming into force from 1st July 2021.

These updated regulations now increase the scope of affected sizes, and types of motor.

As you can imagine, the actual document relating to this legislation is rather lengthy, and somewhat…dare we say, tedious.  

That’s why we’ve pulled out the bits that will be relevant to our customers.

So, here goes…

The Eco-design for Energy-Related Products and Energy Information Regulations 2021.

Eco-design requirements for electric motors and variable speed drives.

Here we’re covering the energy efficiency requirements for motors.

From 1 July 2021, motors must meet the following requirements.

1. The energy efficiency of three-phase motors –

a.     with a rated output equal to or above 0.12kW and below 0.75 kW 

b.     with 2, 4, 6 or 8 poles; and… 

c.      …which are not Ex eb increased safety motors, must correspond to at least the IE2 efficiency level

d.     Braked or non-braked are treated the same

2. The energy efficiency of three-phase motors –

a.     with a rated output equal to or above 0.75kw and equal to or below 1,000kW 

b.     with 2, 4, 6 or 8 poles; and

c.      which are not Ex eb increased safety motors must correspond to at least the IE3 efficiency level.

d.     Braked or non-braked are treated the same.

Excluded are motors with temperature range < -30°C > +60°C
