Product Development

The experienced and well-equipped design team keeps abreast of new materials and cutting edge technology. This knowledge is used to full advantage in the development of new cost effective motors with optimum performance.


SEM is committed to having quality and flexibility at the core of our business.  This is shown through continuous investment in the latest systems and technology within our state of the art manufacturing facility.  The manufacturing system is organised by product value streams which are made up of a number of lean manufacturing cells and processes.  This structure creates a strong customer focus and provides a platform to improve through the use of key performance indicators.  Our operational excellence programme involves an intensive focus on staff development, engagement and training to ensure we continue to improve.  This was recently recognised with an Investors in People award.
