[Webinar] IE4 Induction Motors – Benefits and Challenges

This presentation discusses the benefits and challenges associated with super premium IE4 induction motors, which are now required by the latest EU Ecodesign regulations for power ratings ranging from 75 kW to 200 kW for two, four, and six-pole motors. Initially, the market may view these high-efficiency motors unfavourably due to their higher price compared to IE3 motors.

However, it is crucial to recognise that IE4 motors provide significant advantages and should not be seen as merely an expense, but rather as a smart investment that pays off in a relatively short timeframe. This could very well be one of the simplest and most effective investments a company can make today.

Additionally, the presentation addresses concerns regarding material usage and the actual impact on carbon footprint reduction when considering the entire energy system, from generation to distribution.

Key takeaways

• IE4 Induction Motors are now required by EU Ecodesign Regulation 2019/1781 for 75–200 kW motors (2, 4, and 6 pole types)
• Replacing an IE1 75kW motor with an IE4 version can deliver a full return on investment in under 4 years, thanks to significant efficiency gains
• Lower winding and bearing temperatures extend grease life by up to 40 percent, enabling longer maintenance intervals and reducing downtime
• Existing motors can be upgraded to higher efficiency by replacing aluminium rotors with copper rotors during regular maintenance
• Though IE4 motors cost 20 to 30 percent more, energy savings can repay the extra cost in just 2 years, making them a smart investment
• IE4 motors maintain the same shaft, flange, and foot dimensions as IE3, easing the replacement process
• IE4 motors reduce system-level energy losses, indirectly reducing the material demand for power generation and distribution
• Motor users are encouraged to analyse their installations — replacing old motors can offer compelling operational and sustainability benefits
