Sustainability and climate protection already play an increasingly important role in the private sphere. In industry, too, the importance is increasing: In order to reconcile climate targets with a growing and prosperity-oriented society, increasing energy efficiency in industry is a key lever for reducing energy requirements and limiting global warming. Drive systems are responsible for about 70% of the electricity demand in industry. This makes them the biggest lever for increasing energy efficiency and reducing energy demand. The mechanical engineering industry is facing increasing legal requirements, such as the Ecodesign Directive, and the growing desire of users. Lenze provides concrete and holistic support in optimizing the energy requirements of machines with energy-efficient drive solutions.
International requirements for energy efficiency
The IEC60034-30-1 standard describes energy efficiency classes for three-phase motors using IE codes. However, the standard does not specify any efficiency classes to be complied with. This is done in the regional legislation. As a result, there are requirements for the minimum efficiency of electric motors in almost all markets. We have prepared these country-specific requirements clearly for you and they are available for download here.

CEMEP guide on ecodesign requirements
Three approaches are pursued in order to increase the energy efficiency of drives
1. Using electrical energy intelligently: as little as possible
- Dimensioning according to needs
- Controlled operation (frequency inverter)
- Energy-efficient motion control
2. Converting energy with a high degree of efficiency
- Components with a high degree of efficiency:
motors, gearboxes, inverters
3. Using recovered braking energy
- Energy exchange between several drives
- Temporary storage of braking energy
- Regeneration of braking energy
Energy-efficient Drive Package
What energy-efficient drive solutions does Lenze offer?
Lenze m550 three-phase AC motors already meet all current and known planned energy efficiency regulations, such as efficiency classes IE2 and IE3. In combination with the efficient g500 gearboxes and i550 inverters, this represents a complete and energy-efficient drive package to realize initial savings potential:
Our three-phase motors meet all currently applicable energy efficiency requirements and are optimized for operation with Lenze gearboxes and frequency inverters:
Efficient drive sizing with Drive Solution Designer DSD
Intelligent drive sizing is a prerequisite for an exactly dimensioned and therefore small-as-possible drive solution with just the right components. Thanks to Drive Solution Designer DSD potential energy savings can be seen at a glance and are documented in the Energy Performance Certificate. A clear comparison of different solutions is also made easy.
After all, the Drive Solution Designer DSD provides a simple view of complex sizing knowledge, with well-founded expertise of drive applications such as drive physics, variants or energy efficiency. Drives are sized based on calculations with individual process data and speed profiles, taking the complete structure of the drive into consideration for the requirements of the machine.
