Abstract

See full text

A rotor for a dynamoelectric machine includes a rotor core having an outer periphery and at least a first set of magnets positioned within the outer periphery of the rotor core. The first set of magnets includes at least two block magnets and an arc magnet. The block magnets have a substantially parallel magnetization pattern and the arc magnet has a substantially radial magnetization pattern. The arc magnet has a concave surface facing the outer periphery of the rotor core. The first set of magnets defines a pole of the rotor. Rotors with other magnet configurations, and dynamoelectric machines and compressors incorporating such rotors, are also disclosed.
