07/03/2013 Workshop: Implementing 547/2012/EC 2

Energy related Products (ErP) Directive

• 2009/125/EC Framework Directivefor Ecodesign

• CE-marking relevant

• ‚ErP‘ is any good with impact on energy con-sumption in use, except means of transport


[…]

[…]

Energy related Products Directive

• ‚Placing on the market‘ and/or

‚Putting into service‘

• Regulations under ErP have to be transposed into identical (1:1) national law.

Water Pump Regulations under ErP

• Commission Regulation(EC) No. 640/2009 - Ecodesign requirements for electric motors

• Commission Regulation(EU) No. 547/2012 - Ecodesign requirements for water pumps

Regulation (EC) No. 640/2009 - Scope

Article 2

Definitions

[…]

1. ‘Motor’ means an electric single speed, three-phase 50 Hz or 50/60 Hz, squirrel cage induction motor that: — has 2 to 6 poles,

— has a rated voltage of UN up to 1 000 V,

— has a rated output PN between 0,75 kW and 375 kW,

— is rated on the basis of continuous duty operation (S1, S6-S8)


Regulation (EC) No. 640/2009 - Scope

2. This Regulation shall not apply to:

(a) motors designed to operate wholly immersed in a liquid;

(b) motors completely integrated into a product (for example gear, pump, fan or compressor) of which the energy performance cannot be tested independently from the product;

(c) motors specifically designed to operate: (i) at altitudes exceeding 1 000 metres above sea-level;

(ii) where ambient air temperatures exceed 40 °C;

(iii) in maximum operating temperature above 400 °C;

(iv) where ambient air temperatures are less than – 15 °C for any motor or less than 0 °C for a motor with air cooling;

(v) where the water coolant temperature at the inlet to a product is less than 5 °C or exceeding 25 °C;

(vi) in potentially explosive atmospheres as defined in Directive 94/9/EC of the European Parliament and of the Council ( 3 );

(d) brake motors;


Revised Regulation (EC) No. xxx/2012

2. This Regulation shall not apply to:

(a) motors designed to operate wholly immersed in a liquid;

(b) motors completely integrated into a product (gear, pump, fan or compressor) that cannot be tested separately from the machine even with provision of temporary end shield and drive end-bearing and for which the separation of the motor from the rest of the product would render the motor inoperative

(c) motors specifically designed to operate exculsively: (i) at altitudes exceeding 1 000 4000 metres above sea-level;

(ii) where ambient air temperatures exceed 60 40 °C;

(iii) in maximum operating temperature above 400 °C;

(iv) where ambient air temperatures are less than – 15 20 °C for any motor or less than 0 °C for a motor with air water cooling;
