Firstly, this paper analyzed briefly the principle of the rare-earthless permanent-magnet-assisted synchronous reluctance motor (PMaSynRM), fixed on the characteristics of motor. Then it designed a sort of PMaSynRM used the hard ferrite magnets, and while it was contrasted with the earthless inner permanent magnet synchronous motor (IPMSM) in the same size, got the advantage of application of the PMaSynRM. At last, the rare-earthless PMaSynRM was applied successfully in the variable speed compressor in the fact, and the effect of the application is favorable.
Key words: Rare earthless; permanent-magnetic-assisted synchronous reluctance motor; variable speedcompressor
