The Industrial Applications Society (IAS) in the IEEE Montreal Section cordially invites you to the IAS Prominent Lecture presented by Dr. Mircea Popescu, Head of Engineering, North America with Motor Design Ltd. Please register using the link provided below.

Seminar Abstract
The lecture covers from an industrial perspective some of the latest developments in the subject area and includes timely topics such as heating and ventilation, the torque ripple due to eccentricity, manufacturing technologies like segmented stators for brushless PM machines and die-cast copper rotors for induction motors, the role of computer aided engineering in the industrial environment. The state of the art topologies and the emerging trends are also presented. Particular emphasis is placed on the possible shortage of NdFeB magnets and on potential alternatives for rare-earth free or magnet free solutions.

Various cooling systems for electric machines are illustrated in detail, with a focus on forced convection – air or liquid – methods. A high torque density value is achievable only if an efficient cooling is employed. The merits and problems for the existing cooling system are discussed. Topics such as the risk for PM demagnetization, the effect of switching frequency, supplementary AC losses and magnet losses are discussed.

A comparison between the permanent magnet motor solutions – interior and surface rotor mounted motors – with magnetless solutions – induction motors and reluctance motors is presented. A discussion of the trends and anticipated industry developments is also included.
