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...
This paper presents a linearized demagnetization model taking into account temperature dependence of the hard magnetic material. At the same time, an efficient searching algorithm is proposed to properly identify the new worst working point and update the recoil line during the entire transient solution process if a working point is discovered below the knee point of the current recoil line. This...
