Rotor for a permanent magnet machine starting line

摘要

Abstract of the disclosure is the line start permanent magnet rotor machine, the rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. The laminations also have equiangularly magnet slots spaced about the rotor. The magnet slots extend near to the impeller outer diameter and have permanent magnets disposed therein creating magnetic poles.The magnet slots may be formed longer than the permanent magnets disposed therein and defines one or more magnet slot apertures. The permanent magnets defines the number of poles and pole pitch. The rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch.Conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ translation summary invention patent: "rotor for a permanent magnet machine starting line.The present invention relates to a rotor which comprises laminations with a plurality of apertures of the bar of the rotor with a provision is asymmetric around the rotor. The laminations are also apertures of the magnet equiangulamente spaced around the rotor. The cracks of the magnet extends close to the outer diameter of the rotor are permanent magnets arranged therein and creating magnetic poles.The cracks of the magnet can be formed longer than the permanent magnets disposed therein and defining one or more openings of the slit of the magnet. The permanent magnets define many poles and a step polar. The slits of the rotor bar are spaced from the apertures of the adjacent magnet by a distance that is at least 4% of the step polar.The conductive material is disposed in the apertures of the bar of the rotor, and, in some ways, may be disposed in the openings of the gap of the magnet.
