New design of Variable Speed Starter

The new PowerXL DE1 Variable Speed Starter (VSS) from Eaton made a big impression at the Hannover Messe trade fair. The German Industriepreis 2015 panel of professors, scientists, industry experts and specialist journalists recognized that the PowerXL DE1 VSS fills a gap in the market, for a new device class for motor control that will be particularly useful for helping to increase energy efficiency in applications where fixed-speed starters were previously used. So the Eaton PowerXL DE1 VSS was awarded the Industriepreis 2015 in the Electrical Engineering category.

Government efficiency requirements such as those set out in the ErP Directive, combined with increasing levels of machine automation have seen a significant growth in the use of applications with variable speeds. However, conventional variable speed drives are often too complex for these applications, whilst starters don’t provide the option to control speed. The PowerXL DE1 VSS provides machine and system builders with a cost-efficient and highly reliable new device class for motor control that will be particularly useful for helping them to increase energy efficiency in applications where fixed-speed starters were previously used. The PowerXL DE1 VSS fills a gap in the market, and this is recognized by the Industriepreis award, which recognizes ideas and products which are innovative, production-ready and modern, as well as that help users be more profitable and efficient.

The VSSs have been designed for straightforward ‘out of the box’ operation without the need for adjustments or parameter setting. At the same time, users have at their disposal a universal configuration module that allows the most important parameters to be set using only a screwdriver – no keyboard, software or manual are needed. This means they require up to 80% less commissioning time and cost up to 70% less to install than conventional VSDs.
