14 Energy efficiency

Lenze BlueGreen solutions serve to execute energy efficiency calculations for dimensioned drives.

• A project comparison serves to compare and optimise the different mechanical concepts and

drive components with regard to their energy required.

• You can calculate the share of energy in the production costs and the energy emissions for CO

certificates of the European Union for the entire production line.

• Calculate the investment costs, cost schedules, cost rankings and the overall costs of the drive

system.

• The results of the energy efficiency calculation are approximate values.

• Contact the Lenze sales if you want to calculate the energy efficiency of the drive system un-

der real operating conditions.

• The energy efficiency calculation considers the most important losses in the drive system.

• Considered loss sources: Application, gearbox, additional drive element, motor, inverter, re-

generative power supply module, brake chopper and brake resistors, DC-bus operation.

• Losses of the following components are excepted: Engine fans, Motor fans, motor brakes, fil-

ters, mains chokes, cables, additional modules of the inverter, automation components.

• The losses of the application are based on the efficiency of the application entered in the DSD.
