Electromagnetics PRESENTER:Maged Ibrahim EXPERTISE:Electromagnetics Software:JMAG A novel interior permanent magnet synchronous motor design comprising alternate layers of Permanent Magnet (PM) and Soft Magnetic Composite (SMC) was developed. The fabrication of the proposed design by cold spray additive manufacturing allows to eliminate the bridges and center-posts that are usually present in laminated interior PM rotors fabricated […]

Electromagnetics PRESENTER:Prof. Miller EXPERTISE:Electromagnetics Software:JMAG This talk is about parasitic torques and noise in the induction motor. It’s a personal view. This technical presentation may seem rather low-key. That’s because I’m trying to encourage calm reflection of rather abstract topics, even though this is a very practical subject.
