The Advantages
|
|
|
|
The Danfoss EC+ concept allows permanent magnet (PM) motors with non IEC or IEC conform dimensions to be used with Danfoss VLT® frequency converters.

Simple Commissioning
|
|
|
Many users are familiar with operating standard motors with VLT® HVAC drives. The configuration
settings are essentially the same.

Optimum Efficiency
|
|
|
Improving efficiency is an easy way to reduce energy consumption. The European Union has
therefore introduced minimum efficiency performance standards (MEPS) for three-phase induction motors.

|
|
Manufacturer Independence
|
|
|
|
By applying the Danfoss EC+ concept users benefit from maximum flexibility thanks to the option of choosing different manufacturers for the necessary standard components.

|
Easy Retrofit
|
|
|
|
The EC+ concept is based on standardised components that the user can replace individually. It allows PM motors with IEC dimensions to be used with Danfoss VLT® frequency converters.

Low Service Costs
|
|
|
|
The term “Total Cost of Ownership” (TCO) covers the consideration of all costs incurred during the lifetime of a product. For the EC+ concept, as with all electric drives, the energy costs constitute the largest share.

Legislation & Motor Efficiency Classes
|
|
|
|
To achieve CO2 savings legal measures are taken worldwide. Since a large savings potential is seen in electric drives, they are already subject to many legal regulations.

Motor Technology
|
|
|
|
Due to the built-in permanent magnets, permanently excited motors do not need a separate excitation winding. This results in reduced losses in the motor and in increased efficiency.
