Design of electromagnetic and electromechanical devices has always relied on a good understanding of the behaviour of magnetic materials, including properties such as nonlinearity, losses and residual fields. In the race to reduce energy consumption and meet legislative requirements, accuracy in this area has become vital.

Opera has been at the forefront of the simulation of magnets, motors, transformers, actuators and sensors for over two decades and has demonstrated robust modelling methods for magnetic material performance at macroscopic level, where the characterization can be usefully employed for device simulation. To meet 21st century requirements, advanced modelling capabilities such as hysteresis and demagnetization have also been introduced. In this webinar, we summarize the requirements for device-level modelling of magnetic materials, document Opera's capabilities and illustrate the webinar with examples taken from a variety of industries.

Speaker: Chris Riley, engineering manager, Vector Fields Software
Chris Riley has worked in the field of electromagnetic design for 35 years and joined Vector Fields in 1986. He is currently leading the UK-government-funded technology-innovation project, RapidSR, to develop reluctance motor based electric drives for traction applications in collaboration with Jaguar, Land Rover and Ricardo. He is the author of more than 55 articles and papers, primarily concerned with applications of design software in electrical machines, magnetic and electric signatures from naval vessels and superconducting magnets. He is a Fellow of the Institution of Engineering and Technology.
