Selecting soft starters for use with IE3 motors

Posted by AuCom on 14/07/16 12:48

IE3 motors are now mandatory in Europe for new installations between 7.5 k W and 375 kW. This is in line with elsewhere in the world. (And for a time in Europe, IE2 motors with a variable speed drive may be used for drive-suitable applications)

IE3 motors are more efficient than IE2 motors. The improved efficiency results in lower lifetime energy usage and energy costs, which has obvious value. However, other IE3 motor characteristics are affected by the changes made to achieve this efficiency. For example, the starting torque is lower, and the starting current is higher.

Making the most of premium efficiency motors

Posted by AuCom on 08/06/16 09:18

We are quite possibly witnessing the beginning of an electric motor market boom as stricter energy efficiency regulations are being rolled out around the world. The higher energy efficient standards were predicted to cause worldwide overhauls of newer motor technology, resulting in significant market growth over the coming years.

According to a market report published by Credence Research “Electric Motors Market – Growth, Share, Opportunities, Competitive Analysis, and Forecast 2015 – 2022,” the global electric motors market is expected surpass US$ 135 Bn by 2022.

IE3 motors are now mandatory in Europe for new installations between 7.5 kW and 375 kW, in line with many other jurisdictions in the world.

At the recent energy efficiency in motor-driven systems (Eemods) conference in Finland the new regulations were presented as necessary to help meet the EC’s 2030 target of cutting greenhouse gas emission levels by 40% compared to 1990 levels, as well as cutting energy consumption by 27% by that date. These proposed changes could affect up to 89 million motors and more than four million variable-speed drives sold in the EU every year.

The new EC regulations are expected to increase growth for the replacement market. The rise of industrialisation and the construction industry is predicted to contribute to an increase in the growth of premium efficiency motors.
