BS EN 61800-9-1:2017

What is BS EN 61800‑9‑1‒ Adjustable speed power drive systems about?  

BS EN 61800‑9‑1 is a part of an international product standard that covers adjustable speed electrical power drive systems. 

BS EN 61800‑9‑1 specifies the general methodology to energy efficiency standardization for any extended product by using the guidance of the extended product approach (EPA). It is based on specified calculation models for speed/load profiles, the duty profiles, and relative power losses of appropriate torque versus speed operating points. 

BS EN 61800‑9‑1 specifies the methodology of determination of losses of the extended product and its sub-parts, requirements for the semi-analytic model (SAM) of the extended product and the motor system, etc. for adjustable speed electrical power drive systems.  

Note 1: BS EN 61800‑9‑1 is applicable to motor systems operated by a motor starter or by a converter (power drive systems). 

Note 2: BS EN 61800‑9‑1 does not specify requirements for environmental impact declarations. 

Who is BS EN 61800‑9‑1‒ Adjustable speed power drive systems for? 

BS EN 61800‑9‑1 on adjustable speed power drive systems is useful for the entities dealing with 

the applications: 

• Production test equipment, test benches 
• Papermaking machines, textile production machines,  
• Rubber industry 
• Plastics process lines 
• Chemicals or metal production companies, rolling-mills 
• Cement crushing machines, cement kilns, mixers, centrifuges, extrusion machines 
• Developers of Power Drive System 

Why should you use BS EN 61800‑9‑1‒ Adjustable speed power drive systems?  

Power drive systems contain a group of a pump, an electric motor, adjustable speed controls, and sensors, which permits equipment to vary their speed up to meet demand making the pumps more efficient. 

BS EN 61800‑9‑1 establishes a clear and simple system for the comparison of the energy performance of motor systems that can help you to improve the quality of their products. It gives you the necessary transparency and information, to provide a robust reference base for regulators and minimum energy performance standards. 

BS EN 61800‑9‑1 also enables the product committees for driven equipment connected to the motor systems (extended products), to interface with the relative power losses of the connected motor system. This helps you to calculate the energy efficiency of the system for the whole application. 

What’s changed since the last update?  

BS EN 61800-9-1:2017 supersedes BS EN 50598-1:2014, which is withdrawn.
