    Abstract: A rotor of a permanent magnet synchronous machine includes a rotor core structure. A first set of apertures are formed in a first radial layer of the rotor core structure having a first set of permanent magnets disposed therein forming respective poles. A second set of apertures formed in a second radial layer of the rotor core structure of each pole. A third set of apertures is formed in a third radial layer of the rotor core structure. A second set of permanent magnets is inserted within the third set of apertures. A plurality of bridges each extends across a respective side of each of the third set of apertures in the third radial layer. The plurality of bridges provides structural support of the rotor core structure when operating. The plurality of bridges are integrally formed as single-piece laminations.

    Abstract: A rotor for a permanent magnet synchronous machine that includes a rotor core structure. A first set of permanent magnets forms poles within the rotor core structure. Each pole includes a pair of permanent magnets from the first set of permanent magnets. A first set of apertures is formed in a first radial layer of the rotor core structure. Each pole includes a pair of apertures from the first set of apertures. The first set of permanent magnets is inserted within the first set of apertures. Each pair of permanent magnets within a pole cooperatively generates a magnetic field in a same direction within the pole. The magnetic field generated by a respective pair of magnets in a respective pole is opposite to a magnetic field generated by a pair of permanent magnets in an adjacent pole.

    Abstract: A rotor for a permanent magnet synchronous machine. A first layer of cavities formed circumferentially within the rotor core structure. Pairs of the cavities in the first layer form V-shaped configurations and are spaced circumferentially about the rotor core structure in the first layer. A second layer of cavities is formed circumferentially within the rotor core structure. Pairs of the cavities in the second layer form V-shaped configurations and are spaced circumferentially about the rotor core structure in the second layer. A first set of permanent magnets is inserted within each cavity in the first layer and a second set of permanent magnets inserted within each cavity in the second layer. Each respective V-shaped configuration of the second layer having permanent magnets disposed therein extend greater than half a radial distance from the outer cylindrical wall to the inner cylindrical wall.
