Rotamec offers a selection of IE3 & IE4 motors that are built with either cast iron or aluminium construction. These motors are available in frame sizes ranging from 80 to 180 for aluminium and 80 to 355 for cast iron construction. the Rotamec group prioritises energy efficiency and strives to deliver products that ensure low ownership costs throughout the motor’s lifetime. Additionally, through a network of manufacturers we offer a comprehensive range of products that include IE1 standard efficiency (for non-EUP compliant countries), IE2 high efficiency, IE3, IE4 premium efficiency, and US NEMA premium, catering to various customer requirements.

Variable Speed Drives

Rotamec can supply an array of frequency inverters, also known as variable speed drives, that can help achieve further energy savings. These products can be customized to cater to various requirements. When paired with a high-efficiency electric motor, variable speed drives can maximize energy savings in numerous applications. A prime example of this is variable torque loads, such as centrifugal fans and pumps, where a 10% reduction in speed can lead to a 30% energy savings.
