IEC 61800-9-1:2017

Overview

IEC 61800-9-1:2017 is an international standard published by the International Electrotechnical Commission (IEC), focused on ecodesign requirements for adjustable speed electrical power drive systems, motor starters, power electronics, and their driven applications. The standard provides the general methodology for energy efficiency standardization using the extended product approach (EPA) and semi analytic model (SAM). It identifies how to determine losses within an extended product - meaning a system that includes driven equipment and its connected motor system - and aims to enable efficient comparison and evaluation of energy performance across various industrial electric drive systems.

This standard is crucial for manufacturers, regulators, and industrial users seeking to enhance the energy efficiency of power-driven equipment, particularly in applications where motor systems are operated by a starter or variable speed drive/converter.

Key Topics

• Extended Product Approach (EPA):

  • The EPA methodology evaluates the complete combined system - driven equipment plus motor system - instead of standalone components.
  • It allows for a realistic assessment of energy consumption by factoring in load, operating, and duty profiles.

• Semi Analytic Model (SAM):

  • SAM provides a framework for calculating power losses and efficiency across typical operating points.
  • It uses physical and mathematical parameters to represent components like motors, drives, and driven machines.

• Energy Efficiency Index (EEI):

  • The result of the EPA is the calculation of an Energy Efficiency Index, which quantifies overall energy performance.
  • EEI supports benchmarking and regulatory compliance for energy-efficient product design.

• Standardized Methodology:

  • The standard details how product committees and manufacturers should set up and use EPA and SAM for their applications.
  • It includes requirements for providing relevant torque-speed and duty profiles and for combining manufacturer-provided loss data.

• Applicability and Scope:

  • Applies to motor systems operated by either motor starters or power drive systems (PDS).
  • Specifies loss determination methodologies but does not prescribe environmental impact declaration requirements.

Applications

IEC 61800-9-1:2017 has broad practical applications in various sectors that use motor-driven systems, such as:

• Industrial Automation: Helps optimize motor-driven equipment like pumps, compressors, fans, and conveyors for maximum energy savings.
• Product Development: Enables manufacturers to design and benchmark new motor systems against recognized energy efficiency indicators.
• Regulatory Compliance: Assists authorities and technical committees in setting and validating minimum energy performance standards for industrial equipment.
• Energy Management: Provides facility managers and engineers with a systematic approach to select, configure, and assess power drive systems based on real-life operational profiles.

Related Standards

For comprehensive energy efficiency assessment and compliance, IEC 61800-9-1:2017 is best used in conjunction with other key standards, including:

• IEC 61800-9-2: Specifies energy efficiency indicators for power drive systems and motor starters, essential for loss calculation and EPA implementation.
• IEC 60034-2-1: Defines methods for determining losses and efficiency of rotating electrical machines.
• IEC TS 60034-2-3: Details specific test methods for converter-fed AC induction motors.
• IEC 60050-161: Provides reference electrotechnical vocabulary ensuring clear communication and harmonization.

Conclusion

By establishing a harmonized methodology for energy efficiency standardization in any extended product application, IEC 61800-9-1:2017 is a foundational reference for advancing sustainable and energy-efficient motor systems. Its extended product approach, leveraging detailed analytic modeling, empowers stakeholders to achieve better energy usage, enables transparent benchmarking, and supports compliance with global ecodesign requirements. Using IEC 61800-9-1 alongside related IEC standards ensures a robust, interoperable framework for energy efficiency in modern electrical power drive systems.
