The SAIEE’s Rotating Machines Section proudly presents a Practical Introduction to Industrial Rotating Machines. Structured to share specific information that is not covered in traditional forums, to provide non-specialists in the Rotating Electrical Machines field valuable, modern, practical and useful material – presented by a wide range of five experts in their fields, over a three-day schedule.
The structure of the course has been tailored specifically to provide an introduction to these machines, a thorough treatment of their maintenance management, and a look into the recent and future developments in modern machine topologies and drive types. The course objective is to give the widest range of delegates practical take-home benefits, with local and international relevance from small to very large machines.
