This part of IEC 61800 specifies energy efficiency indicators of power electronics (complete drive modules (CDM), input or output sub drive modules (SDM)), power drive systems (PDS) and motor starters, all used for motor driven equipment.

This document is an Energy Efficiency Publication according to IEC Guide 118 and specifies the methodology for the determination of losses of the complete drive module (CDM), the sub drive module (SDM), the power drive system (PDS) and the motor system.

It defines IE and IES-classes, their limit values and provides test procedures for the classification of the overall losses of the motor system.

Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems. This depends on the architecture of the motor driven system, on the speed/torque profile and on the operating points over time of the driven load equipment. It provides a link for the energy efficiency evaluation and classification of the extended product.

The methodology of the extended product approach and the semi analytical models are defined in IEC 61800-9-1.

The structure of this document is as follows:

the losses of standardized PDS, standardized reference CDM (RCDM) and the mathematical model for their calculation are given and classified;

the reference motor (RM) and the reference CDM (RCDM) are defined. They are used for determining the efficiency class of a PDS if either the physical motor or physical CDM is unknown;

the requirements for the determination of the losses of a physical PDS and a physical CDM including correction factors for other types of CDM as defined as RCDM or SDM are given and compared to the PDS and RCDM;

the requirements for type testing and user documentation are given;

some exemplary losses of an overall system are illustrated in annexes;

information about system and drive topologies are given in annexes.

Specific data for the RCDM and RM, limits for the PDS and IE/IES-classes are given for low voltage (100 V up to and equal to 1 000 V), single axis a.c./a.c. power drive systems with three-phase motors. Geared motors are treated as standard motors when motor and gearbox can be separated. A methodology is given in addition how this reference data can also be applied to other topologies like a.c./d.c.or d.c./a.c.converters.

All provided reference data is derived from PDS with induction motors. It may be used for various types of PDS with other types of motors as well, for example but not limited to, Electronically Commutated Motors (ECM), Permanent Magnet Motors (PM) or Synchronous Reluctance Motors (SYN-RM), and Line-Start Permanent Magnet Motors (LSPM).

PDS requirements in this standard only apply to PDSs that are placed on the market as one single product, i.e. combination of motor and CDM that are not intended to be used separately.

CDM requirements only apply to a CDM where the included SDMs have not already been evaluated according to SDM requirements.

The following equipment is excluded from the scope:

High voltage CDM, SDM and PDS with a rated voltage above 1,0 kV a.c. or 1,5 kV d.c.;

Low voltage CDM, SDM and PDS with a rated voltage below 100 V a.c.;

High power PDS above a rated power of 1 000 kW;

High power CDM and SDM above a rated apparent output power of 1 209 kVA;

Low power PDS below a rated power of 0,12 kW;

Low power CDM and SDM below a rated apparent output power of 0,278 kVA;

PDS with geared motors where motor and gearbox cannot be separated, for example because of a common housing;

Servo PDS (consisting of frequency converter, motor and position feedback sensor);

CDM, BDM and SDM that are exclusively designed to drive servo motors;

PDS, CDM, BDM and SDM specifically designed for d.c. motor applications according to IEC 61800-1;

PDS where several motors are connected in parallel to a single CDM with one three-phase output.

SDM with DC input and DC output

NOTE IEC 61800-9 (all parts) does not cover energy efficiency classification of driven equipment but provides input for the assessment according to the extended product approach.

This part of IEC 61800 specifies the general methodology to energy efficiency standardization for any extended product by using the guidance of the extended product approach (EPA).

This document is a Group Energy Efficiency Publication as defined in IEC Guide 119 with the energy efficiency function to establish a clear and simple system methodology for the comparison of the energy performance of motor systems to help product and system improvement.

It enables product committees for driven equipment connected to motor systems (so called extended products) to interface with the relative power losses of the connected motor system (e.g. power drive system) in order to calculate the system energy efficiency for the whole application.

This is based on specified calculation models for speed/load profiles, the duty profiles and relative power losses of appropriate torque versus speed operating points.

This document is applicable to motor systems operated by a motor starter or by a converter (power drive system).

This document does not specify requirements for environmental impact declarations.

Power Drive Systems designed to drive DC motors are not included in the Scope of this Standard.

the different conditions for transportation, storage, and operation of the transformers;

additional requirements in accordance with other appropriate standards and national rules can be applicable to reactors intended for use in special environments.

Future technological development of reactors can necessitate a need to increase the upper limit of the frequencies. Until then this document can be used as a guidance document.

This group safety publication focusing on safety guidance is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by technical committees in the preparation of publications for products similar to those mentioned in the scope of this group safety publication, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
