Radially embedded permanent magnet rotor and methods thereof

A permanent magnet rotor comprising:

• a shaft comprising an outer diameter;
• an inner hub coupled about said shaft outer diameter;
• an outer hub spaced radially about said inner hub and defining a first space between said outer and inner hubs;
• a plurality of discrete circumferentially-spaced pole pieces positioned radially about and coupled to said outer hub, said plurality of discrete circumferentially-spaced pole pieces defining a plurality of second spaces between adjacent said discrete circumferentially-spaced pole pieces;
• a plurality of permanent magnets positioned radially about said outer hub, each permanent magnet of said plurality of permanent magnets positioned in a respective second space of said plurality of second spaces and spaced from said adjacent discrete circumferentially-spaced pole pieces;
• and
• a non-magnetic material positioned in said first space and said plurality of second spaces, said non-magnetic material coupled to said outer and inner hubs to form a central hub, said central hub configured to magnetically isolate said plurality of discrete pole pieces and said plurality of permanent magnets, and said non-magnetic material coupled to and positioned between said plurality of permanent magnets and said plurality of discrete circumferentially-spaced pole pieces.
