ROTORS WITH SEGMENTED MAGNET CONFIGURATIONS AND RELATED DYNAMOELECTRIC MACHINES AND COMPRESSORS.

摘要

A rotor (100) for a dynamoelectric machine includes a rotor core (102) having an outer periphery (116) and at least a first set of magnets positioned within the outer periphery (116) of the rotor core (102). The first set of magnets includes at least two block magnets (104) and an arc magnet (106). The block magnets (104) have a substantially parallel magnetization pattern and the arc magnet (106) has a substantially radial magnetization pattern. The arc magnet (106) has a concave surface (107) facing the outer periphery (116). The first set of magnets defines a pole of the rotor (100). A dynamoelectric machine and a compressor incorporating such rotor are also disclosed.
