Introduction to Rotating Electrical Machine Design using Opera Webinar
Cobham Technical Services has an on-demand webinar titled, Introduction to Rotating Electrical Machine Design using Opera. The webcast will help designers of electric motors and generators use finite element analysis (FEA) techniques to accelerate product development and improve design accuracy. The online seminar is ideal for electromagnetic and electromechanical analysts, as well as engineers who are currently using analytical design packages for rotating machines. The 47-minute audio/visual presentation is now available in English and French.
The Cobham webinar outlines the fundamental principles of FEA, such as defining model geometry, creating finite elements (meshing) and specifying or importing material properties such as B-H curves. The webcast also takes a detailed look at aspects especially relevant to rotating electrical machines. These include hysteresis loss, the demagnetization effects of short-circuits and other faults, and the critical importance of obtaining an accurate representation of the magnetic field in the rotor-armature air gap.
The presentation discusses how by setting suitable periodicity boundaries, users can reduce the size of the electrical machine model — and therefore the number of equations that need to be solved — significantly, leading to much faster computation times. This is important for designers of high pole count machines, because it enables the analysis model to be a fraction of the full device.
