Abstract :
This paper analyzed the parameters and anti-demagnetization of permanent magnet assisted synchronous reluctance motor(PMSynRM) with concentrated and distributed windings . The operating point formulation of each permanent magnet(PM) layer was deduced by establishing the demagnetization magnetic circuit model of multi-layer PM structure . A method was proposed to improve the anti-demagnetization consistency of each PM layer . Finally a prototype was made depend on this method, the improvement of anti-demagnetization consistency of distributed windings PMSynRM has been verified, the prototype was developed to be applied to the variable speed compressor.
