The profound influence of electronic control is made clear, not only in relation to its history but also for the present and the future. Equally the impact of modern permanent-magnet materials is shown in detail, and the question of scarcity is discussed. DC machines, universal motors, and the important classes of reluctance machines are shown to be full members of today’s family of electric machines with important roles. We hope the webinar will appeal to a wide audience. For anyone new to the industry, it can be used as an introduction. Students may find it helpful in sorting out the confusing array of different machine types. Specialists (including the expert users of sophisticated software tools) may like to take a break and enjoy a wider view. And experienced designers and users may compare their own reflections on the electric machine industry through this unifying review.

This month’s seminar
In this 31st seminar, we will explain the torque ripple in the IPM. This time, we will focus on the saliency, which is a very important feature of IPM motors, and pay attention to the role of harmonics in reluctance torque.
