Modelling of electromagnetic device with permanent magnets using finite element method
(full text in Romanian)

Alexandru RADULIAN


The electromagnetic device with NdFeB permanent magnet is designed to replace traditional mechanical drive system of the VCB vacuum circuit breakers and DC circuit breakers. It has the following advantages: simple structure, small gauge, a high force in the closed position, high mechanical life and is easy to maintain. This paper presents the modeling, simulation and optimization of electromagnetic device using 2D finite element method.

Keywords: rare earth magnets, finite element, optimization, vacuum circuit breakers
