Nonlinear varying-network magnetic circuit analysis for permanent magnet synchronous generator with concentrated windings and outer rotor;

Design of the electromagnetic circuit of a new-type self-holding electromagnetic valve;

Elementary analysis on the formula for magnetic resistance of magnetic circuit;

In this paper,a calculation method of permanent magnet in magnetic path has been introduced,and a high ef-ficient model of magnetic path has been established.

Such nonbreaking Y-shapedcare structure is characterized with its magnetic path symmetry and constructioncompactness.

On comparing moving-iron with moving-coil types of electromechanical converters,a new-type hi-response moving-iron converter was presented,which utilized suspending springs,full-bridge magnetic circuits and single driving coil,therefore it was simple,reliable,and energy-saving.

2 finite element software of large type developed by American IMAG,CO is adopted to analyze the magnetic circuits built in in a new type of a permanent magnetic device under oscillation.

For applyingmagnetic refrigeration to air conditioners and householdrefrigerators ,it is important toforma highfield strengthpermanent magnetic circuit besides applying magnetic re-frigerant materials with giant GMCE.

In this paper, based on hollow cylindrical flux source, the high field strength permanent magnetic circuit for room-temperature magnetic refrigerator have been designed and fabricated.
